泡沫填充密度对纺织增强材料平压性能影响
Influence of Foam Filling Density on Flat Compressive Property of the Textile Reinforcing Material
摘要
Abstract
Influence of foam filling density on flat compressive property of the textile reinforcing material was discussed.Spacer woven fabric was woven with polyester filaments as the raw material.Polyurethane foam was used to fill the fabric gaps.Epoxy resin was used to coat and composite on the board surface.Sandwich type composite board was prepared.By changing the usage amount of polyurethane foam,seven kinds of boards with different filling density were designed and produced.Their flat compressive properties were tested.The test results showed that the flat compressive strength had an overall increasing trend as the increase of filling density.When the density was increased to a limitation,the flat compressive strength started to decrease.Parabolic relation was shown between foam filling density and board flat compressive strength.When the foam filling density was 0.134 5 g/cm3,the biggest flat compressive strength of board was obtained.It is considered that the optimal strength property of textile reinforcing material can be obtained by testing and analyses.关键词
