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
