Nowadays polymer composites are one of the most popular materials in the field of science and applying engineering. They combine various advantages, which are easy to manufacture, cost effectiveness and excellent performance. The great importance is choosing of an appropriate matrix for special composites elements working in different conditions. Very interesting technical material seems to be the thermoplastic resin poly (phenylene sulphide) (PPS) which can be used in automobiles, aircrafts and electro-/electronics technologies. Conventional thermoset composites have in recent years successfully found engineering applications but in contrast to PPS they have been limited for applying at higher temperature and difficulties in recycling. Regarding the lack of knowledge in terms of precise understanding on the failure basis, there has been not many publications on the degradation mechanisms of PPS with short glass fibres. In this article, the PPS/fibre fillers (containing 30% and 40% short glass fibers) has been introduced. It has been showed and discussed the phenomena and structure characterization after three point bending tests. It was carried out the macro- and microstructural observation. The plots of stress vs displacement indicate to brittle materials behaviour. All samples of the PPS 30% and PPS 40% composites subjected to 3-points bending test were destroyed in in the centre of the sample. It was confirmed that in short fibre composites, generally, the failure process is dictated by fibre/matrix separation which usually starts near the fibre ends. The scheme of cracking is similar regardless of fibre content. The bending stresses were higher in the composite with higher volume fraction of fibres.

Istnieje niewiele doniesień w literaturze na temat zjawisk zachodzących w kompozytach termoplastycznych podczas badań wytrzymałościowych, a w szczególności dotyczy to kompozytów wzmacnianych krótkimi włóknami. Dlatego celem artykułu jest analiza zniszczenia i zmian w strukturze kompozytu o osnowie poli(siarczku fenylenu) (PPS) wzmacnianego krótkimi włóknami szklanymi w badaniach wytrzymałości 3-punktowego zginania.
