The aim of the study is to determine the effect of metallic nano- and microparticles entered into laminates with the epoxy resin matrix reinforced with fiberglass.The reference analysis showed that research in the field of composites focus on improving strength properties, including fatigue, resistance to impact, thermal and electrical conductivity and combustibility.Most of the tests are carried out in standard laboratory conditions, whereas in reality these materials often work in the most adverse external conditions. The paper presents the results of epoxy resin laminates fatigue studies. The laminates were reinforced by fiberglass, modified with metallic powders of different granulation including nanopowders.Particular attention was paid to the study of fatigue strength at low temperature and to compare it with the results of standard tests. The tests were performed on a specially designed bench with a mechanical forcing variable load on samples in the form of sidely fixed bar. The bench was equipped with a thermal chamber that allows for the implementation of research at temperatures from - 40 ° C to + 60 ° C.Based on these results, the guideline was developed for the planning of more advanced experiments, the results of which will be the basis for the design of laminates operating at extremely low or elevated temperatures.Keywords: Composites, metallic and ceramic powders, fatigue, low temperatures
