How Crowdsourcing is Accelerating the Future of Materials Manufacturing
Look around you—from the sleek smartphone in your hand to the fuel-efficient aircraft soaring overhead, our modern world is quietly being reshaped by composite materials. These engineered combinations of fibers and resins create substances with exceptional strength-to-weight ratios, corrosion resistance, and design flexibility that traditional metals cannot match1 .
Yet despite their transformative potential, developing and certifying these advanced materials has traditionally been slow, expensive, and fragmented across isolated laboratories and companies.
Enter a revolutionary new approach that is turning this process on its head: crowdsourced manufacturing. By leveraging the collective intelligence and capabilities of distributed researchers, manufacturers, and innovators through digital platforms, the composites industry is undergoing a radical acceleration. At the heart of this transformation lies an innovative platform known as the Composites Design and Manufacturing HUB (cdmHUB), which is convening a global community to advance how we design, simulate, and certify composite materials1 8 .
This article explores how the synergy between composite manufacturing and crowdsourcing is not just changing materials science—it's redefining innovation itself, creating a future where breakthrough technologies emerge from collective intelligence rather than isolated genius.
Imagine a bustling scientific community where researchers from Purdue University share simulation tools with automotive engineers in Germany, where aerospace experts collaborate with marine engineers on certification standards, and where students can access state-of-the-art modeling software that would otherwise cost millions. This is the vision behind cdmHUB—a collaborative web interface platform designed to build synergies among the composites community by enabling 24/7 interaction8 .
The platform's mission centers on advancing "certification by analysis"—a paradigm shift from the current practice of exhaustive physical testing toward trusted simulation methods that can significantly reduce development time and cost8 .
Major aircraft manufacturers spend millions of dollars and thousands of man-hours annually testing and retesting designs for certification8 . cdmHUB aims to transform this process through simulation and collaboration.
cdmHUB hosts a growing suite of simulation tools that researchers and engineers can access directly through their web browsers8 .
The platform employs an innovative classification system that evaluates simulation tools across seven levels of maturity8 .
Beyond research tools, cdmHUB serves as an educational repository with online presentations, courses, and learning modules8 .
The power of cdmHUB lies not just in its technological capabilities but in its community-driven approach—creating what amounts to a continuously evolving, self-improving ecosystem for composites innovation.
While the concept of crowdsourcing gained fame through platforms like Wikipedia and Kickstarter, its application in manufacturing represents one of the most promising—and perhaps surprising—developments in Industry 4.0. Crowdsourced manufacturing organizes a dynamic resource-sharing mechanism across manufacturers to create production networks from a large population of manufacturers3 .
Unlike traditional outsourcing with its predetermined suppliers, crowdsourcing employs open calls to a diverse crowd to maximize the exploitation of external resources and capabilities3 . This approach creates what researchers call a "socio-economic cyber platform" where products and services are created and delivered collaboratively in a distributed manner3 .
The process typically involves four key players3 :
A company or researcher seeking manufacturing solutions
Distributed manufacturers, designers, and engineers
Digital infrastructure connecting the ecosystem
Beneficiary of collaboratively developed products
When NASA needed to design a compact, efficient restroom for lunar missions, they turned to crowdsourcing platform HeroX, offering $35,000 in prizes for the top three designs.
The vehicle manufacturer maintains an open-innovation platform that allows external contributors to submit ideas, leading to award-winning products like the three-wheeled Slingshot motorcycle.
Following the 2010 oil spill, BP initiated a crowdsourcing effort that invited external experts and the public to submit innovative solutions for containing and cleaning up the massive environmental disaster6 .
The technological foundation for this manufacturing revolution relies on what Industry 4.0 researchers call "ubiquitous connectivity"—the ability to collect significant volumes of dispersed information and support distributed decision-making through advances in IoT, cloud computing, and blockchain technologies3 .
While the digital transformation of composites research is impressive, the physical creation of these materials still follows fundamental principles that remain constant across different manufacturing methods. Understanding these steps helps appreciate why collaboration and simulation are so valuable in this field.
| Step | Purpose | Key Methods | Output |
|---|---|---|---|
| Impregnation | Thoroughly coat fibers with resin | Resin baths, prepreg materials, automated application | "Lamina" (single layer of coated fibers) |
| Layup | Position materials in desired orientation and location | Manual placement, automated fiber placement, filament winding | "Preform" (stacked layers ready for curing) |
| Consolidation | Create monolithic structure, remove voids, achieve dimensional accuracy | Vacuum bagging, hydraulic presses, compaction rollers | Consolidated structure with proper fiber volume |
| Solidification | Harden resin into final form | Heat curing (thermosets), cooling (thermoplastics) | Finished composite part |
These steps form what composites engineers call the "process chain," where each stage influences the final material properties9 . For example, imperfections in impregnation can lead to weak spots, while errors in layup orientation can dramatically reduce strength in critical directions.
Dry fibers positioned in a mold first, then resin infused under vacuum pressure2 .
What makes cdmHUB particularly valuable is its ability to simulate each of these manufacturing steps, helping researchers optimize parameters like resin flow, curing kinetics, and fiber orientation before committing to physical prototypes.
To illustrate how materials innovation works in practice, consider a groundbreaking 2025 study that explored using sisal fibers—derived from a drought-resistant succulent plant—as sustainable reinforcements for automotive composites7 . This experiment exemplifies the type of research that collaborative platforms can accelerate by sharing both methodologies and results.
Researchers employed the hand lay-up technique, one of the most accessible composite manufacturing methods, but enhanced it with precise scientific controls7 . The process followed these steps:
Sisal fibers were cut to a uniform 20mm length and randomly distributed at different weight fractions (5%, 10%, 15%, and 20%).
A release agent was applied to prevent the composite from adhering to the mold surface.
Fibers were meticulously positioned in the mold, then polyester resin was poured and distributed evenly.
Layers were built up while removing air bubbles, then underwent controlled curing.
The findings demonstrated that plant-based fibers could compete with traditional synthetic reinforcements in specific applications while offering environmental benefits.
| Fiber Content | Tensile Strength (MPa) | Flexural Strength (MPa) | Impact Strength (J) | Compressive Strength (MPa) |
|---|---|---|---|---|
| 5% | 4.39 | 47.17 | 1.33 | 14.46 |
| 10% | 16.72 | 48.90 | 4.00 | 25.85 |
| 15% | 17.44 | 52.65 | 6.66 | 36.80 |
| 20% | 14.51 | 49.38 | 16.00 | 52.40 |
The data reveals several important trends. Mechanical properties generally improved with increasing fiber content up to a point, with 15% fiber content emerging as the optimal balance for most applications. Surprisingly, at 20% fiber content, impact strength and compressive strength continued to improve dramatically, while tensile and flexural strength showed slight declines—highlighting the complex relationships between fiber concentration and different mechanical properties.
| Property | Value | Significance |
|---|---|---|
| Tensile Strength | 17.44 MPa | Suitable for structural components |
| Flexural Strength | 52.65 MPa | Excellent resistance to bending |
| Shear Strength | 77.97 MPa | Strong internal layer adhesion |
| Impact Strength | 6.66 J | Good energy absorption |
| Compressive Strength | 36.80 MPa | Adequate for load-bearing applications |
| Thermal Stability | Up to 300°C | Suitable for automotive applications |
Thermal analysis confirmed the composites maintained stability up to 300°C, with rapid degradation occurring above 400°C—more than adequate for automotive interior applications like dashboards7 .
Free vibration tests recorded a natural frequency of 67.38 Hz with a damping ratio of 0.059, while dynamic mechanical analysis reported a storage modulus up to 7.5 GPa.
This sisal fiber study exemplifies precisely the type of research that benefits from crowdsourced platforms like cdmHUB. By sharing detailed methodologies, data, and simulation models, other researchers can:
The implications extend beyond automotive applications to aerospace interiors, construction materials, consumer products, and other fields where sustainability matters alongside performance.
Creating advanced composites requires specialized materials, each serving specific functions in the final material system. Here are key components from our featured experiment and their roles in composite manufacturing:
This toolkit represents just a fraction of the materials available to composites researchers, but demonstrates how each component contributes to the final material's performance, processability, and cost.
As platforms like cdmHUB continue to evolve and crowdsourcing becomes increasingly sophisticated, several emerging trends suggest where composite manufacturing is headed:
Machine learning algorithms will increasingly help match problems with relevant experts within the crowd, predict material performance, and optimize manufacturing parameters.
Virtual replicas of physical manufacturing processes will enable researchers to run simulations that accurately predict real-world outcomes, dramatically reducing development cycles.
Distributed ledger technologies will provide secure ways to track contributions and manage intellectual property in collaborative environments3 .
As evidenced by the sisal fiber study, there is growing emphasis on developing eco-friendly composites that maintain performance while reducing environmental impact7 .
The convergence of these technologies suggests a future where materials development occurs not in years or decades, but in weeks or months—where sustainable alternatives to energy-intensive materials become commonplace, and where innovation becomes truly democratized across global communities of researchers, manufacturers, and innovators.
The transformation of composite manufacturing from a specialized, proprietary process to a collaborative, crowdsourced endeavor represents more than just a technical shift—it signals a fundamental change in how humanity solves complex material challenges. By leveraging platforms like cdmHUB, the composites community is creating what might be called a "collective intelligence advantage" where the whole truly becomes greater than the sum of its parts.
This approach is particularly valuable for composites because of their inherent complexity—where manufacturing parameters, material combinations, and structural designs interact in countless ways that no single organization can fully explore alone. The crowd sourcing model allows for parallel exploration of multiple solutions, rapid validation through shared simulation tools, and accelerated adoption of successful innovations across industry boundaries.
As this collaborative ecosystem continues to mature, we stand at the threshold of a new era in materials science—one where breakthrough composites emerge not from isolated laboratories but from interconnected communities working together to build a stronger, lighter, and more sustainable future.
