摘要: 采用试验方法对3组不同温度下层合板胶接头(T100/T500)的拉伸破坏力学性能进行了研究.试验结果表明,高温试样初始破坏载荷约为室温试样的1/2,但最终破坏载荷均值为室温试样的1.79倍,而低温试样的最终破坏载荷的均值为室温试样的72.64%.因此,胶接头(T100/T500)在高温条件下的力学性能要优于常温和低温条件下的力学性能.Abstract: The tensile crippling mechanical property of composite laminate cementing(T100/T500) under three different temperatures were studied by experiment.The results of the experiment proved that the first crippling load of the high temperatures was only half of the room temperature specimens,the ultimate failure load reached 1.79 fold of the room temperature specimens,and the average maximum load of the low temperatures specimens was 72.64% of the room temperature specimens.The mechanical property of the cementing (T100/T500) under the high temperature was superior to the others.
