【摘要】 为满足大型空间展开机构的复合材料需要,采用拉挤工艺制备复合材料柔性杆。通过微观形貌分析、力学性能测试和高低温循环实验考查玻璃纤维/环氧树脂体系的复合材料柔性杆的工艺性、力学性能和耐温性能。实验表明,复合材料柔性杆的纤维在树脂体系中分布均匀,无孔隙分层等缺陷;表观水平剪切强度达96.18MPa、弯曲强度达1622.55MPa、模量达56.86CPa及极限应变达2.78%,经±100℃高低温循环后,仍具有良好的结构稳定性。更多还原

【Abstract】 In order to meet the needs of large space deployable mechanism of composite materials pultrusion process,the preparation of composite flexible rod.Through the microstructure analysis,mechanical property testing and high temperature cycle test of glass fiber/epoxy resin system technology,composite flexible rod mechanical properties and heat resistance.Experiments show that the composite flexible rod fiber evenly distributed in the resin system,non porous delamination defects;apparent horizontal shear strength of 96.18 MPa and flexural strength of1622.55 MPa,56.86 GPa and ultimate strain modulus at 2.78%±100℃,the high temperature cycle,still has good stability.更多还原
