Tensile and compression tests for samples immersed in 12.5 g/dm3 sodium hydroxide solution and without sodium hydroxide solution were performed using a universal testing machine （Monsanto tensometer）. The results from the tensile test indicate that stress is fairly proportional to strain. However, the tensile strength increases （reduction in strain）, as the soaking time increases for the treated composites. The untreated samples demonstrate reduced tensile strength compared to the treated composites under hygrothermal conditions. The conditioned samples in each case show better tensile and compressive strength compared to the untreated samples. The plant coconut fibres investigated demonstrate acceptable mechanical properties similar to the synthetic counterparts.展开更多
