Abstract
PMC (Polymer Matrix Composites), in addition to static loads, can also be exposed to dynamic loads as a result of impacts. Aircraft or cars are particularly vulnerable to this type of loading, where small objects, e.g. pebbles, sand grains, and metal debris may hit. Such loads can cause cracking or lead to complete damage. Therefore, the paper presents research results for the most commonly used polymer composite reinforced with glass fibers (GFRP). For GFRP samples, hand lay-up lamination was used. The tests were carried out using SHPB (Split Hopkinson Pressure Bar) the device equipped with steel bars with a diameter of 20.5 mm. Three load levels were used: 1 bar (≈1000 1/s), 1.5bars (≈1500 1/s) and 2bars (≈2000 1/s). The dimensions of the samples were 12 × 12mm, and the thickness was depending on the tested material. The analysis of the results was carried out in the WASP (Waves Analysis and Study Program) program, obtaining the true stress – true strain diagrams.
