Analysis of Damage Area of Fiberglass/Polyester Bi-Panel with Rice Husk Ash as a Filler Caused by the Impact of High-Speed Particles

Analysis of the damaged area of the composite bi-panel fiberglass/polyester with the addition of rice husk ash as a filler have been presented in this paper. The area of damage is caused by the impact of high-speed particles. Bi-panel composites were made by hand lay-up of S-glass and unsaturated polyester resin BTQN 157 ex with variations of 3, 5, 7, 9 %v rice husk ash as a filler. The impact test were carried out using a 9 mm caliber FN gun in accordance with NIJ level IIIA standards. The results show the area of damage caused by a projectile decrease with the increasing amount of Rice husk %v. There is a significant effect with the addition of rice husk ash filler on the composite of bi-panel fiberglass/polyester to the impact of high-speed particles. The rice husk ash could be used as an alternative for filler in Polyester/Fiberglass composite for body armor application.
