铺层混杂对复合材料层压板侵彻性能的影响

本文利用MTS和冲击侵彻测试装置，研究了由芳香族聚酰胺纤维、高强聚乙烯醇纤维制成的织物通过不同铺层方式与酚醛/PVB树脂复合的层压板的准静态和冲击侵彻性能。结果表明，芳香族聚酰胺织物层的加入能显著提高高强维纶织物树脂复合材料层压板的准静态侵彻刚度。随着芳纶混杂体积分数的提高，铺层混杂复合材料层压板的准静态侵彻阻力、穿孔能量（或单位面密度穿孔能量）将随之增加。从防护装具性能/重量比和性能/价格比的角度考虑，在芳香族聚酰胺与高强聚乙烯醇织物铺层混杂复合材料层压板中，高强聚乙烯醇纤维混杂体积分数可以确定为20%左右。

Influence of Ply Stacking Hybrid on Penetration Properties of Composite Laminates

The quasi-static and dynamic impact penetration properties of ply stacking hybrid composite laminates made from phenolic/PVB resin and two kinds of fabric woven respectively by aramid fibers and high strengh polyvinl alcohol fibers are investigated by means of MTS (Material Test System) and ballistic impact test apparatus. The results show the quasi-static penetration stiffness of ply stacking hybrod composite laminates can be increased obviously when aramid woven fabric plies are inserted brtween high strengh polyvinl aclcohol woven fabric plies. The resistance of quasi-static penetratin and perforation energy increase with rising of the aramid fibers volume fraction in the total fibers. From the point of view of the ratio of properties to weight and the ratio of properties to price for protective armor, the optimum volume fraction of high strengh polyvinl alcohol fiber can be ascertained about 20% in the ply stacking hybrid composite laminates of aramid woven fabric and polyvinl alcohol woven fabric.
