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.

拟议的程序涉及加载历史对半晶聚合物（SCP）机械性能变化的影响及其充满玻璃填充的复合材料。该程序的动机来自发现机械性能的变化，这是由于塑料管道行业实际上可以接受的维修或定期维护所接受的机械性能的变化。提出了三个项目，其中总体目标是开发知识和技术，以评估SCP和SCP复合材料的裂纹启动和增长的可能性，这些材料旨在长期携带负载应用。
