Effect of Alkalization on Mechanical Propertiesof Water Hyacinth Fibers-Unsaturated Polyester composites.

Characteristic of local water hyacinth (WH) fibers and composites that consist of mixing WH fibers and unsaturated polyester (UPR) were studied. Composites mixed with the WH fibers treated in different alkali concentration for 1 h soaking time were tested by tensile and flexure machine and their fra...

Composites mixed with the WH fibers treated in different alkali concentration for 1 h soaking time were tested by tensile and flexure machine and their fracture surface was observed by using scanning electron microscope (SEM).

From SEM observation, some untreated WH fibers pulled out from their matrix were observed clearly in fracture surface of composites.
