高强高模PVA纤维的研究现状及在防弹复合材料中的应用

The Present Research Situation of High-Tenacity and High-Modules PVA Fibre and Its Application in Ballistics Composite Material

高强高模ＰＶＡ纤维具有断裂比功大、易于粘接、价格低廉、易于国产化等优点，与芳纶混用制备防弹复合材料可在降低成本的基础上获得良好的防弹效果。本文在论述高强高模ＰＶＡ纤维发展状况的基础上，分析测试了典型高强高模ＰＶＡ纤维的抗冲击性能，进行了ＰＶＡ／芳纶混杂复合防弹靶板的试制实验。

High-tenacity and high-modulus PVA fibre has the advantage of large specific rupture,easy adhension, low price and simple domestic producing. The ballistics composite material made of PVA fibre blending with aramid fibre can achieve a good ballistics effect on a basis of reducing cost. The paper first gives a background of the hightenacity and hgih-modulus PVA fibre,and then tests and analyses the impact resistance property of typical hightenacity and hgih-modulus PVA fibre. A trial test of PVA/aramid composite ballistics target plate is also discussed.
