The proposed program is concerned about the influence of loading history on the change in mechanical properties for semi-crystalline polymers (SCP) and their glass-filled composites. Motivation for the program comes from the discovery of changes in mechanical properties owing to the loading conditions that are actually acceptable by plastic pipe industry for repair or regular maintenance. Three projects are proposed, of which the overall objective is to develop knowledge and technology to assess the possibility of crack initiation and growth in SCP and SCP composites that are intended for long-term, load-carrying applications.

本文研究了加载历史对半晶聚合物（SCP）及其玻璃填充复合材料力学性能变化的影响。该计划的动机来自于发现由于塑料管道行业实际上可以接受的修复或定期维护的加载条件而导致的机械性能变化。提出了三个项目，其总体目标是开发知识和技术，以评估用于长期承载应用的SCP和SCP复合材料裂纹萌生和扩展的可能性。
