It is difficult to obtain accurate compressive strength using existing methods. Direct compressive tests were performed to investigate the compressive strength of high performance polymer fiber. The compressive test pieces were manufactured by using photolithography technology. Finite element analysis was performed to decide optimal fiber length. Finite element analysis results show that fiber length less than 20 μm has much influence on stress distribution. It was found that the compressive strength of high performance polymer fiber was well represented by normal distribution. However, the scatter of compressive strength was large. This is attributed to compressive failure occurred in nonuniformly-distributed stress region.
