繊維強化材料及び構造体

Japanese Patent JP6946653

B2

Disclosed herein are a fiber-reinforced material and an article which are hard to break. The fiber-reinforced material includes a fiber assembly 15 and a matrix material 12 coating the fiber assembly 15, wherein the matrix material 12 is a thermoplastic resin composition obtained by blending a polyolefin resin, a polyamide resin, and a modified elastomer having a reactive group that reacts with the polyamide resin. When a puncture test is performed at a striker speed of 1 m/sec or more but 4 m/sec or less and when a deflection when a maximum impact force is applied is defined as P_Mand a deflection at break is defined as P_B, P_B/P_M≥4. Further, when the amount of energy absorbed before a maximum impact force is applied is defined as E₁, the amount of energy absorbed after a maximum impact force is applied and before break is defined as E₂, and a total amount of absorbed energy of E₁and E₂is defined as E_T, the ratio of E₂to E_Tis 70% or more. The article is made of the fiber-reinforced material.
