Accession number: 20122715215063 Title: Structural design and anti-explosion experiment of UHMWPE-PUF composite Authors: Cai, Junfeng1 ; Yi, Jianzheng1; Zhao, Ran1 Author affiliation: 1 Department of Ammunition Engineering, Ordnance Engineering College, Shijiazhuang 050003, China Corresponding author: Cai, J. (cabbagecjf@163.com) Source title: Gaofenzi Cailiao Kexue Yu Gongcheng/Polymeric Materials Science and Engineering Abbreviated source title: Gaofenzi Cailiao Kexue Yu Gongcheng Volume: 28 Issue: 5 Issue date: May 2012 Publication year: 2012 Pages: 69-72 Language: Chinese ISSN: 10007555 CODEN: GCKGEI Document type: Journal article (JA) Publisher: Chengdu University of Science and Technology, 24 South Section 1, Yihuan Rd., Chengdu, 610065, China Abstract: Ultra high molecular weight polyethylene (UHMWPE)- polyurethane foam (PUF) composite was synthesized by laminated composite technology and the anti-explosion experiment of composite was designed. The pressure in material under explosion load was measured directly by custom-built polyvinylidene fluoride (PVDF) piezoelectric sensor. Shock wave attenuation properties of UHMWPE-PUF composite were studied by experimental method. The results show that UHMWPE-PUF composite can give full play to the high-strength high-model feature of UHMWPE material and the energy absorbing property of polyurethane foam material, and the low strength imperfection of polyurethane foam plastics was offset by UHMWPE material. The experiment shows shock wave attenuation ability of UHMWPE-PUF composite can improve by 50% than of pure PUF material. The strength and shock wave attenuation properties of UHMWPE-PUF composites were maximally improved. The materials have a good applied outlook in the realm of anti-explosion.
