芳纶针织增强体头盔制作及基本性能研究

为了进一步拓宽芳纶纤维的应用发展,采用手糊成型的方法制作芳纶纤维针织增强体头盔,对头盔的外观、质量、规格尺寸、涂层涂膜附着力、阻燃性能、耐热性能及防水性能进行了测试与分析,结果表明:芳纶纤维针织增强头盔接近中号、光滑、质轻;涂膜附着力达到三级以上;头盔外部灼烧10s树脂无变化,头盔内部灼烧8s火焰熄灭;可耐40℃温度;在水中变化很细微,阻燃性能、耐热性能及防水性能优异。

Production and Basic Properties Study of Aramid Knitted Reinforced Helmet

In order to further enlarge the application development of aramid fiber, aramid fiber knitted reinforced helmets were produced by adopting hand lay-up molding.Helmets' appearance, quality, specification, coating film adhesion, flame retardancy, heat resistance and water resistance were tested and analyzed.The results showed that such helmets were close to medium size, smooth, soft and light;coating adhesion reached more than level three;resin remained unchanged within 10s burning outside the helmet and flame extinguished within 8s inside the helmet;it could withstand a temperature of 40℃ and keep very subtle changes in water with excellent flame retardant property, heat resistance and water resistance.
