Compressive Properties of High-distance Warp-knitted Spacer Flexible Composite

摘要

This paper mainly introduces a high-distance warp-knitted spacer flexible composite material which is a special material consisting of high-distance warp-knitted spacer fabric and some coating materials. It introduces the designing process as well as the preparation of high-distance warp-knitted flexible composite material. In order to comprehend the influence of internal pressure on the material, the mechanical properties under 100 %, 80 % and 60 % gas pressure have been explored. A compression test under these three kinds of gas pressure was carried out and the related force displacement diagram, the stress-strain curve and the energy strain curve which directly reflects the variation of the mechanical properties of the composites material under the different gas pressure were obtained and presented. A deep investigation and analysis was conducted into knowing the compressive properties of the material and how they are affected by the gas pressure. The experimental results obtained shows that the compressive properties of the high-distance warp-knitted space flexible material is dependent on the amount of gas inserted. Again the compressive strength of the material keeps growing stronger with an increase in the intensity of the gas pressure.
