dc.description.abstractThe experiment conducted describes the effect of the use of technological waste on the mechanical behavior of a composite reinforced with short-length glass fibers. This requirement was postulated in course of cooperation with a manufacturing company active in producing components for the automotive industry. In its production of components, the company generates a large volume of technological waste, which is not re-processed at the moment. The material selected for the experiment was Ultradur B 4406 G6 Q717, which is the most frequently one used by the company. It is a composite with a polymeric matrix of PBT and a filler with short glass fibers, accounting for 30% of its volume. Mechanical properties were tested from both, the short-term view, and in terms of the life of the parts. The value of the tensile strength limit decreased by 13.3% in total, correlating with the amount of the recycled material added. Upon exposure to elevated temperature, the tensile strength limit increased by 13%. The modulus of tensile elasticity in short-term tests dropped by 5.4% and increased by 2% upon exposure to elevated temperature. Electron microscopy was used to evaluate interaction at the interstage. A similar trend was noted in evaluation of the flexural strength. The flexural strength dropped by 16.4% in total, correlating with the increase in the amount of recycled material added. Upon exposure to elevated temperature, the flexural strength increased within the range of 0.4-10.4%.cs
