Coir is a well-known natural fiber extracted from the husk of a coconut tree.In polymer composite here materials, the ultimate performance of coir has been shown using surface modification methods.Among them, sodium hydroxide (NaOH) is a comparative and efficient solution used for surface treatment of lignocellulosic fiber.

In contrast to coir, coconut timber, a hardwood that dominates the weight of the coconut tree, has not been appropriately considered for use in polymer composites.Therefore, in this article, coconut trunk particle/unsaturated polyester resin composites were experimentally investigated.As a pioneering study, a large camo iphone se case range of NaOH concentrations from 2 wt% to 10 wt% (with an interval of 2 wt%) was utilized to treat the surface of the filler.

Finally, 4 wt% alkali solution was found as the best content for surface modification based on the mechanical properties of the composite, including those determined by tensile, flexural, and impact test results.
