| 摘 要： | 碳纤维增强铝合金层合板（CARALL）是由碳纤维复合材料和铝合金薄板制成的，由于碳纤维复合材料和铝合金的热膨胀系数相差很大，加热固化后会产生较大的残余热应力。本文对碳纤维增强铝合金层合板中残余热应力进行了分析，并在碳纤维增强铝合金层合板的加热固化阶段，使用二次加热法来降低碳纤维复合材料和铝合金薄板的粘结温度，从而降低残余热应力。

| Abstract: | This research is about the analysis and reduction of thermal residual stress in CFRP/Al laminates(CARALL),which is fabricated by carbon fiber reinforced plastic(CFRP)combined with aluminum alloy(AL).Large thermal residual stress in the aluminum alloy is generated during the curing process of CARALL due to the large mismatch of the coefficient of thermal expansion(CTE)between CFRP and aluminum alloy.Several methods are investigated to determine the thermal residual stress in CFRP/Al laminates and different t... |
