EFFECTS OF REPAIR ANGLES ON THE TEMPERATURE AND THERMAL STRESS OF COMPOSITE PATCHES DURING CURING PROCESS
摘要
Abstract
The physical and mathematical models of composite patches during curing process are established using finite element analysis.The temperature field and the thermal stress field of resin matrix composite patches in different repair angles are simulated during curing process.The effects of repair angles on temperature,curing degree and thermal stress of patches are studied.The results show that,the smaller the repair angles are,the larger of the temperature peak and the thermal stress at the center of patch,and the faster of the curing rate will be.At decentered point of patch,the curing rate is faster,the thermal stress is smaller for small repair angles than that for larger one,and the repair angles have important effect on the value of the thermal stress.Based on the comprehensive analysis,it can be concluded that,within the scope of the repair angles,the repair angles is smaller,the repair quality of composite patches is better.The research results provide the good numerical basis for the actual repair.关键词
