摘要

环境和节能的压力导致对经济上可行的轻质材料的需求急剧增加，这种材料可以更好地取代增强复合材料中的不可生物降解材料。为此，本研究考察了用处理过和未处理过的阿尔法纤维增强不饱和聚酯树脂制备的复合材料。采用5%浓度的NaOH溶液在不同时间(1、3、5、24 h)对纤维进行处理，按照ASTM D790试验方法对复合材料的强度和抗弯模量进行评价。分析结果表明，纤维的碱前处理时间对复合材料的力学性能有积极影响。

"EFFECT OF ALKALINE TREATMENT TIME ON FLEXURAL PROPERTIES OF ALFA FIBER/UNSATURATED POLYESTER COMPOSITE "

Environmental and energy conservation pressure has led to a dramatic increase in the need for economically feasible lightweight materials that can be better substituted for non-biodegradable materials in reinforced composites. To this end, this study examines composite materials prepared from unsaturated polyester resins reinforced with treated and untreated Alfa fibers. Fiber treatment was carried out by NaOH solution of 5% concentration at different times (1, 3, 5 and 24 h). The strength and flexural modulus of the composites were evaluated according to the ASTM D790 test method. The analytical results indicate that the fibers’ alkaline pretreatment time had a positive influence on the mechanical properties of the composites.
