The aim of the research is to analyze and to describe model-based the environmental stress cracking resistance of short fiber reinforced amorphous thermoplastics as a function of the orientation state of the fibers and matrix-related properties. The environmental stress cracking is one of the most common failure reasons of plastic parts during their use. It refers to a premature failure of a polymeric material under mechanical stress with simultaneous action of an environmental medium. One approach to minimize the risk of environmental stress cracking, is the use of short-fiber reinforcements. Research shows that the susceptibility to stress cracking can be significantly reduced. However, own preliminary investigations show clearly that the failure is significantly affected by the local orientation state of the reinforcing fibers. So far, no basic studies can be found in the literature for this purpose. The proposed project is intended to fill this research gap.

研究的目的是分析和描述基于模型的环境应力开裂的短纤维增强非晶热塑性塑料的纤维和矩阵相关的性能的取向状态的函数。环境应力开裂是塑料件在使用过程中最常见的失效原因之一。它是指聚合物材料在机械应力和环境介质同时作用下的过早失效。最大限度地减少环境应力开裂风险的一种方法是使用短纤维增强材料。研究表明，应力开裂的敏感性可以显着降低。然而，自己的初步调查清楚地表明，故障是显着影响的增强纤维的局部取向状态。到目前为止，在文献中还没有找到这方面的基础研究。该项目旨在填补这一研究空白。
