Influence of collision speed on the residual durability of CFRP

Abstract

The results of research of the influence of the collision speed of the striker with the surface of CFRP on the damage square (interlayer delamination) and residual strength of CFRP are shown. The researches were carried out on the samples of CFRP based on unidirectional and equal-strength (twill weave) reinforcing fillers and epoxy matrix with addition of the thermoplastic dispersed filler, made by method of autoclave molding. The speed of collision was changed by changing the height of falling of the striker of the vertical coper. The area of damage was evaluated by method of ultrasonic control.

Keywords
impact, residual compressive strength after impact, CFRP, autoclave molding, mass of load, collision speed, damage area
