| Abstract Scope |
The study of the natural degradation is of fundamental importance when the degradation is combined with heat, solar radiation, pollution and static or fatigue loads, and also conditions that lead to the aging of the materials with decreasing properties of resistance and rigidity. Therefore, in this work the response to the ballistic impact of a composite composed of sisal fabric and epoxy matrix exposed to radiation for 75, 160 and 225 hours was evaluated. The impact tests were performed at subsonic speed using a 150 bar compressed air draft system. Fourier transform infrared spectroscopy (FTIR) was also performed to observe changes after radiation exposure. The results indicated that the composite obtained good kinetic energy absorption performance, by capturing projectiles, or greatly reducing their velocities. |
