high strength and high elastic modulus for its weight.) Mixing. This makes different fibre types more suitable for some applications than others. This failure is not catastrophic - because not all fibers fail at the same time, and - even after fibers failure the matrix is still intact until it is strained to its fracture point. For continuous-fiber reinforced composites … 4 . Structural composites . Discontinuous strands of carbon fiber or fiberglass are most frequently used to reinforce plastics in 3-D printing processes across every market sector, including … The mixing of nanoparticles with polymers to form composite materials has been practiced for decades.
