Thermal cold fatigue of glass mat reinforced polypropylene has been studied by measuring the flexural property and dynamic mechanical property of the composites and the interfacial shear strength of the single filament specimen after thermal cold cycling treatment in different ranges of temperature. The results show that thermal cold cycle leads to the interfacial failure and reduction in mechanical properties. The interfacial failure due to thermal stress will increase with increasing the range of temperature and the number of cycles. Under the same conditions, the interfacial failure of composites differs for different relaxation of the thermal stress of interfaces.

通过测定玻璃纤维毡增强聚丙烯复合材料在不同温度区间内经冷热循环后的弯曲性能和动态力学性能以及玻璃纤维增强聚丙烯复合体系经冷热循环后界面剪切强度的变化 ,研究了该材料的冷热循环疲劳特性。结果表明 ,在一定温度区间内的冷热循环会对玻璃纤维毡增强聚丙烯的界面造成损伤 ,使材料的力学性能下降 ;随着冷热循环温度区间温差的增大、冷端温度的降低、循环次数的增多 ,形成的热应力对材料的界面损伤越严重 ;不同的复合体系由于其界面松弛热应力的能力不同 ,在同样条件下的冷热循环过程中 ,界面所受到的损伤程度有差异。

s In this paper the environmental damage to interface of glass fiber reinforced PP(GF/PP)was studied by measuring interfacial shear strenght with a single silament fragmentation technique.The results showed the interfacial debonding would take place either in a hydrothermal environment or undergoing thermal cold cycle.When the glass fiber was treated by coupling agent to form strong interfacial bond,the hydrothermal stability of the interface would be increased.The introduction of flexible interlayer could reduce the thermal cold fatigue of interface.Compared with the composite of weak interfacial adhesion,the composite with good interfacial adhesion showed more retention in interfacial bond strength after thermal cold cycling.

采用单丝临界长度法测定了玻璃纤维增强聚丙烯复合体系的界面剪切强度,研究了湿热及交替变化的温度等环境因素对复合体系界面的损伤。结果表明,湿热及高、低温的冷热循环均能引起玻璃纤维与聚丙烯复合体系的界面脱粘;采用偶联剂处理玻璃纤维、在体系中形成较强的界面粘结( 如化学键结合) ,可提高复合体系界面抗湿热损伤的能力;在复合体系中引入容易变形的界面柔性层可提高体系界面的冷热循环疲劳性能,界面结合较强的复合体系经冷热循环后,仍能保持较高的界面结合强度。
