Analysis of Stabbing Performance of UHMWPE Fabric at Different Angles

Abstract:

Flexible stab-resistant fabrics have been widely used in military and civilian fields; however, there are few researches about effects of incidence angle on stabbing performance of fabrics. Thereof, the stab-resistant mechanism of fabric is investigated from raw material selection, fabric preparation and quasi-static stab-resistant performance test. We analyzed and obtained the modes of interaction between knife and fabric and the mutual influence between the fabrics through different angles and the compound way at different angles. Results show that with the increasing of the angle of incidence, the cutting forces of fabric decrease and the strength reducing rate of fabric increases. The strength trend of compound fabric at different angles is the same as single layer fabric; however, the strength reducing rate firstly increases then decreases. It may be explained that there exists interaction between the fabrics in the cutting process.
