Abstract

This paper presents a study regarding the obtaining, characterizing and mechanically testing a new laminar composite material, consisting of epoxy resin reinforced with basalt plain fabric. The composites were obtained by manual lay-up, cross-link stage being developed by pressure molding in a hydraulic press. Rectangular plates were obtained and cut into samples with specific shapes, for the mechanical tests (tensile, three-point bending and compression). After testing, the fracture zone was analyzed using optical microscopy to observe the behavior of the composite following the mechanical stresses applied (fracture mechanism, voids presence and fiber delamination identification). Due to the low costs and non-hazardous nature, basalt fibers can be a serious competitor in the production of laminar composites that could successfully replace ordinary glass fiber composites. The mechanical properties in tensile, three-point bending, and compression of epoxy-resin-impregnated basalt fiber composites are comparable and even exceed those of widely used epoxy-resin-impregnated fiberglass composites.

玄武岩纤维/环氧树脂复合材料的机械性能

本文介绍了一种新型层状复合材料的获取、表征和机械测试研究，该材料由环氧树脂和玄武岩平纹织物增强而成。得到的矩形板切割成特定形状的样品，用于机械测试（拉伸、三点弯曲和压缩）。测试结束后，使用光学显微镜对断裂区进行分析，以观察复合材料在受到机械应力后的行为（断裂机制、空隙存在和纤维分层识别）。环氧树脂浸渍玄武岩纤维复合材料在拉伸、三点弯曲和压缩方面的机械性能与广泛使用的环氧树脂浸渍玻璃纤维复合材料相当，甚至超过后者。
