Thermoplastic fibers are deposited like cobwebs on top of rigid fibers to chemically form a supportive network with a surrounding matrix, or binder substance. The composites already have many good things going for them. They are also corrosion- and fatigue-resistant and can be tailored to meet specific industrial performance requirements. By using this simple, scalable and low-cost approach, we are able to increase the strength of the composites by almost 60% and its toughness by 100%.
