Study of the Influence Factors for Ballistic Performance of Glass Fiber Reinforced Composites

Abstract

Abstract The study prepares glass fiber reinforced composites through Vacuum Assisted Resin Infusion (VARI) process, selects glass fibers of different specifications, and studies the effects of lay-up mode, thickness, simulated normal incident angle, and temperature of fiber composites s on their ballistic performance. Results show that with slimmer fiber monofilament, reinforced materials perform better in ballistics; the lay-up mode has limited influence on ballistic performance; the relationship between thickness and ballistic performance is positively linear; and the relationship between normal incident angle and ballistic performance is parabolic. Compared with room temperature conditions, the ballistic performance of composites does not decrease and even increases slightly under low temperatures. Yet, the performance decreases sharply at high temperatures.
