GLASS FIBER MAT FOR STAMPABLE SHEET, PROCESS FOR THE PRODUCTION OF THE MAT, STAMPABLE SHEET MADE FROM SAID MAT, PROCESS FOR THE PRODUCTION OF THE SHEET, AND EQUIPMENT FOR THE PRODUCTION THEREOF

摘要

A glass fiber mat for a stampable sheet, in which long fiber and short fiber may not separate even by forming and both are distributed uniformly to make features of respective fibers effective. A production system includes a double belt press type laminator which stacks the glass fiber mat, a thermoplastic resin melt and a film which is taken up and applies heat and pressure for impregnation, and cools with maintaining a condition applied the pressure, supply means for supplying the glass fiber mat into said laminator, and a pair of pressure shearing rollers arranged between the supply means and an endless belt of said laminator for partially cutting the glass fiber into short fiber. The roller is made of steel to apply line pressure on to the glass fiber mat to shear the continuous fiber to uniformly distribute short fiber in long fiber. IMAGE
