Composite materials are made by combining two or more constituent materials, such as resins and fibers, to form an overall material with distinctly different properties from the individual components. The resins, commonly called matrices, bind the fibers together and protect them from damage. Composites offer significantly improved strength, stiffness and toughness compared to traditional materials.
New Advances in Equipment
A major area of innovation and development in the Sports Composites space has been fiber reinforcement. Carbon fiber has become the gold standard due to its high strength-to-weight ratio and fatigue resistance. However, ongoing research has led to new materials like aramid (Kevlar) and ultra-high molecular weight polyethylene (UHMWPE) fibers which offer impressive reinforcement properties at a lower cost than carbon. Hybrid reinforcement using blends of different fibers is also quite common to achieve the desired balance of properties.
Materials Development Enables New Designs
Sports Composites Equipment manufacturers have more design freedom than ever before thanks to materials advances. Lighter and stiffer composites allow equipment to be engineered for optimal performance characteristics. Bicycle frames, tennis rackets, golf clubs and protective gear can be precisely sculpted for high strength in critical areas with minimal excess weight. Internal geometries are also designed to wring out every last ounce of efficiency. Overall, composites have transformed equipment from rigid, bulky structures to lightweight, customizable high-performance tools.
The Growth of Thermoset Composites in Sports
Thermoset composites, often called fiber-reinforced plastics (FRP), were some of the earliest composites to see widespread use in sports. Epoxy is the most common matrix for applications requiring high mechanical properties, resistance to solvents and heat. It provides great adhesion to fibers and cures irreversibly into a very durable final part. While more difficult to produce than thermoplastics, epoxy components are often the only choice for equipment subjected to repeated high loads in harsh environments. Items like bicycle frames, kayaks, snowboards and protective gear shells rely heavily on thermoset composites.
Thermoplastics Enable New Manufacturing Techniques
The thermoplastic category of composites continues gaining traction in the sports market due to manufacturing advantages over thermosets. Thermoplastics matrices like polyamide and polypropylene can be repeatedly softened/hardened through heating/cooling cycles, allowing manufacturing techniques like injection molding, thermoforming, welding and reuse of scrap material. These techniques increase production rates and lower waste. Thermoplastic parts are also fully recyclable at end of life. Inline hockey sticks, snowboard core materials, helmets and protective padding are common sports applications for thermoplastic composites.
Composites Facilitate 3D Printed Equipment
Additive manufacturing (3D printing) of composite parts has started transforming Equipment design and production. Integrating fibers directly into 3D printed thermoplastic matrices allows customized internal geometries and complex external shapes to be created in a single step. This enables lightweight open truss bicycle frames, ergonomic running shoes with varying densities, and protective gear perfectly fitted to an individual. 3D printed composites also have applications in rapid prototyping and custom equipment for individuals. As designs and materials develop further, 3D printed composites are poised to grow substantially in the sports industry.
Moving the Industry Towards Sustainability
Sustainability has swiftly become a massive priority for Sports Composites makers as consumers increasingly prefer brands embracing green initiatives. Composites lend themselves well to more environmentally responsible production compared to traditional materials.
Manufacturing waste from prepreg thermoset production is being reduced through automation while innovation in recycled thermoplastics is helping drive a circular economy approach. Additionally, many major sports leagues are pushing equipment suppliers to use recycled fibers and plant-derived bio-resins to lessen dependency on non-renewables. Composites will play an essential role in bringing the multi-billion dollar sports industry to a lower carbon future.
