Cissus Populnea Fiber - Unsaturated Polyester Composites: Mechanical Properties and Interfacial Adhesion

ABSTRACT

Mechanical (flexural, hardness, and impact) properties and interfacial adhesion of acetic anhydride (AC) and ethylene diamine tetraacetic acid (EDTA) treated Cissus populnea fiber-unsaturated polyester (UPR) composites was investigated because of poor durability of the natural fiber-UPR composite applications. UPR composites were prepared with untreated and optimally treated fiber using hand-lay-up technique. Optimization of mechanical properties and interfacial adhesion between the fiber and UPR were determined using response surface methodology and fiber pull-out method, respectively. AC and EDTA treated fibers improved the flexural and hardness properties and interfacial adhesion at reduced impact strength. This is corroborated with morphology of the composites.

摘要

由于天然纤维-不饱和聚酯复合材料应用耐久性差，研究了经乙酸酐（AC）和乙二胺四乙酸（EDTA）处理的Cissuspopulnea.纤维不饱和聚酯（UPR）复合材料的力学性能（弯曲、硬度和冲击）和界面粘附性.采用响应面法和纤维拔出法分别对纤维与不饱和聚酯的力学性能和界面粘接性能进行了优化.乙酸酐和乙二胺四乙酸处理过的纤维在降低冲击强度时改善了弯曲和硬度性能以及界面粘附性.这与复合材料的形貌相符.
