| 摘 要： | 利用湿法手工铺叠工艺和紫外光固化技术,制备以双酚A环氧树脂E-44与有机硅环氧树脂ES-06共混改性光敏树脂体系为基体的玻璃布增强复合材料,测试并分析比较了复合材料的力学和热老化性能.结果表明,在光敏树脂基体中加入链转移剂以及对光固化后的复合材料进行加压后固化处理,均能显著提高复合材料的性能.采用E-44与ES-06质量比为2:1的共混改性树脂体系制备的复合材料的力学性能和耐热老化性能最佳,其拉伸强度达到146.6 MPa,拉伸模量为19.4GPa,弯曲强度为152.5MPa,层间剪切强度达到16.2 MPa.

| Abstract: | The glass cloth reinforced composites were fabricated by the wet lay-up technique and UV irradiation using blends with both bisphenol-A type epoxide oligomer E-44 and silicone-epoxy resin ES-06 in the presence of diaryliodonium salt cationic photoinitiator.The mechanical and thermal ageing properties of the composites were evaluated.The measurements shows that the properties of the UV-cured composite are improved significantly by postcure/pressure treatment in the presence of the chain transfer agent.Both mechanical and thermal ageing properties of the blended resin matrix composites which the mass ratio of E-44 and ES06 is 2 to 1 are better than others.Its tensile strength,tensile modulus,flexural strength and shear strength is 146.6 MPa,19.4 GPa,152.5 MPa and 16.2 MPa respectively. |
