摘要/Abstract

摘要： 为了安全生产，设计了一种用于防护金属雷管爆炸破片的织物，该织物由超高分子聚乙烯（UHMWPE）和苎麻两种纱线构成双层袋状结构，每个袋内嵌入10×60mm规格的碳纤维树脂复合片材(CFR)。在自制雷管爆炸实验装置上与未嵌入CFR片的双层袋状织物和CFR裸片对比，试验表明：织物防爆能力主要由CFR和UHMWPE承担；未嵌入CFR片时织物中UHMWPE易因熔融被破坏；裸CFR片对破片阻挡能力较差；嵌入CFR片后的袋状织物对815雷管破片的阻挡率提高了55.6%，UHMWPE被熔融而破坏的现象明显降低，但袋与袋间隙处仍易被破片穿透。

Abstract: In order to contribute to the security of production of detonators, a kind of fabric is designed to defense metal detonator explosion splinters. The fabric is formed by double-layer pouch structure constructed by two kinds of yarn, i.e. UHMWPE and ramie. In each pouch a CFR of 10*60mm size is embedded. In comparison to the double-layer pouch fabric not embedded with CFR and bare CFR chips, the experiments show that, 1. the explosion prevention is mainly assumed by CFR and UHMWPE; 2. UHMWPE is apt to melt and damage when not embedded with CFR; 3. bare CFR chips performs poor in shielding against splinters; 4. the fabric embedded with CFR gained a 55.6% improvement in its shielding rate against 815 detonator splinters, and the situation that UHMWPE melts and damages decreased eminently in frequency, but the space between pouches is apt to be penetrated by splinters. Keywords: UHMWPE fiber; carbon fiber reinforced polymer; Explosion-proof performance; shielding rate of detonator splinter

Key words: UHMWPE, ramie multi-compound fabric, carbon fiber reinforced polymer, explosion-proof performance
