Les stratifiés composites hautes performances semi-cristallins sont des candidats pour l’industrie aéronautique. The use of substances like magnesium hydroxide presents a new approach in polymer tribology and could potentially establish smart materials that are able to dynamically react to changing circumstances via a load-dependant manipulation of the tribological contact. By impeding damage on the integrated fibres and by a reaction turnover dependant scarring effect, the released reaction particles have the highest impact. Compared to an unfilled reference and two control materials, a significant and stable performance increase was achieved over a wide load spectrum. It introduced a weak spot in low load segments due to a temporary unfavourable interaction between tribochemical and abrasive effects. The chemical transformation, initiated by friction induced heat, was confirmed. The thesis examines the influence of this filler on the mechanical and thermal properties of a polyamide 66 and, through extensive tribological and surface analytical methods, illuminates the fundamental modes of action. The systematic use of chemical transformation processes by incorporating reactive fillers like magnesium hydroxide promises a solution. The contact temperatures have a negative impact on the system’s performance, particularly during variable loading profiles or when using engineering thermoplastics. The trend is marked by research and development regarding the effectiveness of different material compositions in reducing friction and wear, in which friction induced heat is one of the main challenges. Driven by necessary energy and cost savings, plastics are increasingly applied as primary components in tribological systems.
