Abstract

Abstract Epoxies as a thermoset polymer have got a great attention in different applications. To elaborate their employing and surmount their brittleness, many polymers were blended with them. The results confirm that the good mechanical properties are obtained when 6wt% of Polysulfide Rubber (PSR) is blended with epoxy and reinforced with fiber glass. The effect of rubber and glass fiber on the viscoelastic properties of epoxy were investigated using creep-recovery data under different stress levels (5, 10, 15 and 20 MPa) and temperatures (30, 50, 70 and 90°C). Polysulfide addition caused larger creep and creep recovery. In addition, the creep resistance of glass fiber reinforced blend was significantly enhanced.

玻璃纤维增强橡胶改性环氧树脂的粘弹性行为

摘要环氧树脂作为一种热固性聚合物，在不同的应用中受到了极大的关注。为了详细说明它们的用途并克服它们的脆性，许多聚合物与它们混合。结果表明，6wt%的聚硫橡胶（PSR）与环氧树脂共混并用玻璃纤维增强，可获得良好的力学性能。利用不同应力水平（5、10、15和20MPa）和温度（30、50、70和90°C）下的蠕变恢复数据，研究了橡胶和玻璃纤维对环氧树脂粘弹性的影响。多硫化物的加入引起了较大的蠕变和蠕变恢复。此外，玻璃纤维增强共混物的抗蠕变性能显著提高。

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
