METHOD FOR PREPARING COMPOSITE SHEET HAVING EXCELLENT ECOMOMICAL EFFICIENCY AND PHYSICAL PROPERTY, APPARATUS THEREOF AND COMPOSITE SHEET PREPARED THEREFROM

摘要

PURPOSE: A method for preparing composite sheet having excellent economical efficiency and physical property, an apparatus thereof and a composite sheet prepared thereof are provided to improve the intensity and rigidity by the polymer powder. CONSTITUTION: A method for preparing composite sheet is as followings: a step of spreading the first polymer powder at the upper part of the release film(10); a step of laminating the reinforcing material on the spread first polymer powder; a step of spreading the second polymer powder on the laminated reinforcing material; a step that the first and the spread second polymer powder are heated and fused; a step of compressing the polymer powder and the fused reinforcing material.
