The effect of heat treatment on mechanical properties of car interior fabric used for injection molding
(0) The purpose of this paper is to study the effect of high temperature in injection molding process on mechanical properties of the warp-knitted and nonwoven composite fabrics (WNC)used in car interior.Tensile,tearing and peeling properties of WNC fabrics were tested after heat treatment under120,140,160,180° C respectively.It was found that,after 140° C heat treatment,the breaking and tearing value of these WNC fabrics are lower than others.The results of this study show that this phenomenon is due to the material properties of fabrics.These high temperatures have no much effect on peeling properties of these WNC fabrics.It is concluded that in order to preserve the mechanical properties of these WNC fabrics,the temperature near 140° C should be avoided possibly during injection molding process.
