由於複合材料高比強度和高比勁度(specific strength & stiffness)的特性，使纖維強化的高分子基材複合材料成為近來廣泛應用的高性能(high-performance)結構材料。此外，複合材料結構通常以耐久性(durability)的觀點進行設計，所以"可修補性"(repairability)也是複合材料結構設計上的一個重要的考量。熱塑性基材複合材料比熱固性基材複合材料具有易修補的特性，因為樹酯基材在受到如脫層或是基材裂縫的損傷時能夠重新固化(resolidation)將基材裂縫移除並使脫層部分重新黏合，所以本文將採碳纖維強化熱塑性樹酯複合材料以重新加溫加壓的熱壓成形法(thermoforming)對受軸向拉伸負載與扭轉疲勞後的試片進行修補的工作。本文將針對擬均向(quasi-isotropic)[0/+45/90/-45]2S疊層之碳纖維/聚醚醚酮(graphite/PEEK)複合材料基層疊板試片，首先承受應力等級為80% σ0的軸向拉伸和最大扭轉角等於400的扭轉疲勞，在軸向疲勞負載週次/破壞週次分別等於0.2、0.6與扭轉疲勞經900週次時以熱壓法對試片進行修補，觀察熱壓法對複合材料受軸向拉伸及扭轉疲勞的修補效率(repair efficiency)，其中包括修補對疲勞性質與殘留強度的影響；希望能藉此提供一個能使複合材料提昇受破壞後靜態拉伸和拉伸疲勞性質的方法。
