Coir is a well-known natural fiber extracted from the husk of a coconut tree. In polymer composite 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 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.

碱处理椰子树干颗粒/聚酯复合材料的力学性能

椰壳纤维是从椰子树皮中提取的众所周知的天然纤维。在聚合物复合材料中,已使用表面改性方法显示了椰壳纤维的最终性能。其中,氢氧化钠(NaOH)是用于木质纤维素纤维表面处理的比较有效的溶液。与椰壳纤维相反,椰子木是一种占椰子树重量较重的硬木,尚未适当考虑用于聚合物复合材料中。因此,在本文中,对椰子树干颗粒/不饱和聚酯树脂复合材料进行了实验研究。作为一项开创性研究,使用了从2 wt%到10 wt%(间隔为2 wt%)的较大范围的NaOH浓度来处理填料的表面。最后,
