Influence of the reinforcement on the destruction image of the composites panels after applying impact load

This article presents result of the researches regarding puncture resistance of the multi-layer composite with reinforcement made of aramid fibers and epoxy matrix. Resin has been mixed with curing agents with different viscosity and amine number (Aradur 3486 and Aradur 3487) and aliphatic polyanine (Aradur 3405). Authors compare results of that researches with result of researches concerning on puncture resistance of epoxy – carbon multi-layer material. Part of the tested samples were subjected to ageing process in thermal shocks conditions (-20/+130˚C - with 105 min holding in each temperature and 30 min on temperature change). Puncture resistance researches were performer with different values of penetrators kinetic energy. A steel cylinder ended with a cone (opening angle 60°) with the mass of 55g have been used as a penetrator. Experiment have been performed on hybrid electromagnetic launcher with pneumatic support. Comparison of the anti-penetration properties have been done based on cavity diameter at the sample created in result of penetrator impact.
