FIELD: fiber materials.
SUBSTANCE: group of inventions relates to fiber-reinforced material and an article including such material. The fiber-reinforced material includes a fiber assembly consisting of fiber having a length of 15 mm or more and matrix material covering the fiber assembly, the matrix material being a thermoplastic resin composition obtained by mixing polyolefin resin, polyamide resin and a modified elastomer having a reactive group which reacts with polyamide resin. The proportion of the polyolefin resin is in the range of 20 to 78% by weight, the proportion of polyamide resin is in the range of 15 to 72% by weight, and the proportion of the modified elastomer is in the range of 5 to 53% by weight based on 100% by weight of the total content of polyolefin resin, polyamide resin and modified elastomer. The thermoplastic resin composition has a continuous phase (A) containing polyolefin resin and a dispersed phase (B) dispersed in the continuous phase (A) and containing polyamide resin if the puncture test is performed at a striker speed of 1-4 m/s. If the deflection deformation (mm) at the maximum impact load (L) is defined as PM and the deflection deformation (mm) at fracture is defined as PB, then PB / PM≥4.
EFFECT: group of inventions provides fiber-reinforced material and an article that is more difficult to break due to the effect of increasing the energy expended on the transition from cracking to breaking.
