摘    要:以某飞行器透波结构件对材料的要求为背景,研制了可用于RTM成形工艺的耐高温树脂SH。SH树脂100℃下8h后粘度仅200mPa.s,适于RTM工艺成形;该树脂耐热性良好,玻璃化转变温度Tg为269℃,430℃热失重仅为10%;石英纤维/SH树脂腹合材料300℃时的弯曲强度σb=139MPa,弯曲模量Eb=9.5GPa,可在300℃以上短时使用。

关 键 词:RTM成形工艺  耐高温树脂  粘度  玻璃化转变温度  热失重  弯曲强度  透波结构件  透波材料

Abstract:Heat-resistant resin for RTM process is prepared,which could be used for missile radomes.Viscosity of the resin is only obout 200 mPa· s after 8 h at 100℃,which is very suitable for RTM process.The cured resin has good heat resistance with Ts of 269℃ and weight loss of 10% at 430℃.Flexual strength of 139 MPa and modulus of 9.5 GPa at 300℃ is obtained for quartz fiber/resin composite,which could be used for a short term at this temperature.
Keywords:RTM  Heat  resistant resin  Viscosity    T    g  Weight loss  Flexual strength  Flexual modulus
