摘要/Abstract

摘要： 本文对改性热固性丁苯树脂(GPSB)复合材料进行了人造海水加速老化试验。研究了GPSB复合材料在人造海水中的吸湿特性和吸湿机理。采用红外光谱分析了材料树脂基体中的化学结构变化。采用电子万能试验机和动态机械分析仪考察了试验前后GPSB复合材料的静态和动态力学性能变化。结果表明,经人造海水老化50天,材料的弯曲强度和层间剪切强度的保留率分别为66.6%和55.3%,储能模量降低。电学性能研究表明,老化试验后,材料的介电性能得到保持。采用扫描电子显微镜观察了人造海水腐蚀前后复合材料界面形貌,发现GPSB复合材料的人造海水腐蚀老化主要发生在树脂和玻璃纤维的界面。

Abstract: Modified thermoset butadiene-styrene (GPSB) composite was accelerating aging tested in artificial seawater. The hygroscopic properties and mechanism of GPSB composite was studied. The changes of chemical structures of GPSB composite before and after test were characterized by FTIR. The changes of static and dynamic mechanical properties were analyzed by electronic universal testing machine and DMA. The results showed that the bending strength's and interlaminar shear strength's retention rates were 66.6% and 55.3% after aging 50 days in artificial seawater, and the storage modulus was significantly reduced. The dielectric property test showed that the change of dielectric properties was tiny after aging. The interface bonding performance was investigated by SEM before and after aging. The results showed that GPSB composite corrosion aging occured mainly in the interface of resin and glass fiber.

Key words: thermoset butadiene-styrene, synthetic seawater, aging, composite
