摘　　要：采用微波固化技术,对玻璃纤维缠绕复合材料进行了固化试验研究。综合运用DSC、FT-IR、SEM和力学性能测试等方法手段,分析了材料的固化行为、微观形态及力学性能,并与热固化试样进行了对比。研究结果表明,微波固化能显著提高固化反应速率,相比热固化缩短了81%的固化周期;微波固化过程中并未引入新的化学反应,且两种固化方式下,复合材料具有相似的玻璃化转变温度(Tg);微波固化试样的拉伸强度要高于热固化试样约5%,而层间剪切强度及纤维-基体界面粘接情况与热固化试样相当;相比于热固化复合材料,微波固化复合材料的力学性能离散程度较低。Experimental study was carried out on the glass fiber filament-wound composites with microwave（MW） curing technique.The curing behavior, microstructure and mechanical properties of the cured composites were investigated by differential scanning calorimeter （ DSC ）, fourier transform infrared spectrum （ FT-IR ）, scanning electron microscope （ SEM ） and mechanical testing. The obtained results were compared with those of conventional thermally cured composites.The study shows that MW curing could dramatically enhance the curing rate and a 81% cure cycle time reduction is achieved. MWs do not initiate any new chemical reaction during the curing process and composites using both curing methods show similar glass transition temperature（Tg）. Moreover, the MW cured composites exhibit 5% higher tensile strength, comparable interlaminar shear strength （ILSS）and interfacial bonding properties compared with thermally cured counterparts.Furthermore,lower dispersion of mechanical properties is also found for MW cured composites.
