Nowadays there are numerous ways of making parts of polymer composite materials. The main controlled properties of a part depending on a used technology are porosity and binder percentage, which influence on quality and strength of a part, and also manufacturing cycle time and costs of the used equipment. The main aim of the research was to increase the efficiency of the PCM moulding comparing to the resin infusion method. For reaching the aim there was developed the moulding technology with using elastic diaphragm inflation, as well as there were conducted series of tests by using the dynamo-mechanic analyzer. The way of making the mould and pattern of reinforcing plies layout were offered. For technology approbation there were made a serie of carbon fiber reinforced plastic sport helmets, and got results of time properties of manufacturing. It was discovered that the number of parts made for the time unit by using the inflation method twice exceeds the number of ones made by vacuum infusion method. Specific properties of constructions made by the offered technology also exceed properties of parts made by traditional methods. Inflation technology was successfully put in production and proved its efficiency, reliability and profitability.

The purpose of this work is to compare the impregnation degree of samples made from an aramid-polyurethane composite material produced by three methods of winding. The para-aramid impregnation degree assessment was made on the basis of a microscopic examination of a sample’s section, as well as the results of determining the delamination fracture toughness of ring samples. Based on the studies, it was concluded that the best impregnation degree for para-aramid fibers is achieved in case of using binder sputtering assisted dry winding technology. This technology can be used for high-pressure flexible pipes manufacturing to increase their strength, which can lead to the product’s working pressure increasing.
