摘要

A systematic study was performed to describe the effect of epoxidized soybean oil (ESO) on storage modulus, glass transition temperature (T-g) and mechanical properties in epoxy resin composites reinforced by jute fabric. In addition to aromatic diglycidylether of bisphenol-A (DGEBA) resin, a glycerol (GER)-and a pentaerythritol (PER)-based aliphatic resin was applied as base resin, which can be also synthesized from renewable feedstock. Based on strip tensile test results, the usual alkali treatment of jute fabric was avoided. By increasing the ESO-content in aliphatic composites the Tg increases, whereas in case of DGEBA, it decreases. The results indicate that although ESO has a significant softening effect, the jute fiber-reinforced DGEBA composite can be replaced without significant compromise in mechanical properties by a potentially fully bio-based composite consisting of 25 mass% ESO-containing aliphatic PER-reinforced by jute fibers.
