Reinforced epoxy

WebThe fracture toughness of carbon fiber reinforced plastics is governed by the following mechanisms: 1) debonding between the carbon fiber and polymer matrix, 2) fiber pull-out, and 3) delamination between the CFRP sheets. [5] Typical epoxy-based CFRPs exhibit virtually no plasticity, with less than 0.5% strain to failure. WebMoreover, the dynamic bond enables the epoxy to have admirable degradability, which is demonstrated to be used as an attractive green degradable insulation coating. When used as the matrix for fiber-reinforced composites, the reclaimed glass fibers after …
