Para-aramid fibers (Kolon) are high performance polymeric fibers characterized by their high tenacity and impact resistance. They are used for the soft body armor structures in ballistics. In this study, the testing specimens were made from multilayered Kolon fabrics impregnated with epoxy resin where silicon carbide (SiC) microparticles or SiC nanofibers were added as reinforcement. The laminated composite samples were fabricated by hot compression and curing of epoxy resin.

The tensile and impact strengths of the untreated specimens were compared with the ones that underwent water absorption in duration of 72 h (immersion or humidity) followed by desorption. The immersion of the specimens in water and exposure to high humidity (70%) were performed according to the ISO 62 standard while the tensile test was carried out in accordance with the ASTM D 3039 standard. In the end, the tensile test simulation of the laminated composite by using software Abaqus® was accomplished.

对位芳族聚酰胺纤维（Kolon）是高性能聚合物纤维，具有高韧性和耐冲击性。它们用于弹道学中的软装甲结构。在这项研究中，测试样品是由多层环氧树脂浸渍的Kolon织物制成的，其中添加了碳化硅（SiC）微粒或SiC纳米纤维作为增强材料。通过环氧树脂的热压和固化来制造层压的复合样品。

将未处理样品的拉伸强度和冲击强度与72小时内（吸水或潮湿）吸水并随后解吸的样品的拉伸强度和冲击强度进行了比较。根据ISO 62标准将样品浸入水中并暴露在高湿度（70％）下，同时根据ASTM D 3039标准进行拉伸试验。最后，使用软件Abaqus®对层压复合材料进行了拉伸试验模拟。
