摘要：

Water absorption of natural fibre plastic composites is a serious concern especially for their potential outdoor applications. In this research, jute fibre reinforced with unsaturated polyester composites are subjected to water immersion tests in order to study the effects of water absorption in its mechanical properties. Water absorption tests were conducted by immersing composite specimens into three different environmental conditions included distilled water, sea water and acidic solutions at room temperature for a period up to 3 weeks. Water absorption curves obtained and characteristic parameter D (diffusion coefficient) and M. (maximum moisture content) were determined. The water absorption of jute fibre reinforced unsaturated polyester composites were found to follow a so-called pseudo-Fickian behaviour. The effects of the immersion treatment on the flexural and compression characteristics were investigated. The flexural and compression properties were found to decrease with the increase in percentage water uptake. These flexural and compression behaviours were explained by the plasticization of the matrix-fibre interface and swelling of the jute fibres. (C) 2009 Elsevier Ltd. All rights reserved.
