光固化ES/CEP共混物及其复合材料力学性能研究
STUDY ON THE MECHANICS PERFORMANCE OF ES/CEP BLENDING AND ITS COMPOSITE MATERIALS WITH UV CURING
摘要
Abstract
The blend mixed by silicon epoxies and cycloaliphatic epoxide resin which has different mass ratio is designed.Also, ES/CEP polymer sample (EP), GF reinforced composite (GF/ES-CEP) and repair aluminum alloy specimens with GF/ES-CEP composite as patch are prepared through UV curing technology.We mainly study the impact of the mass fraction of silicon epoxies (ES) on the tensile mechanical properties of samples.The results show that:with ES added into CEP, the tensile strength of EP had gradually decline, while the elongation increased after the first drop, mechanical properties of EP with 15% of ES reached best;GF/ES-CEP composites tensile strength and elongation were falling after the first increase with the increase of the proportion of ES.Moreover, repair aluminum alloy specimens with GF/ES-CEP composite as patch mainly appeared debonding failure between collagen and injury structural interface.It showed that the mechanical property of composites was superior to interface mechanical characteristic.After the water bathing treatment, the mechanical properties of GF/ES-CEP composite repair aluminum alloy samples would decrease significantly, and adding suitable amount of organic silicon resin can improve the wet and heat resistant of repair specimen.关键词
