COMPOSITE BOARD HAVING EXCELLENT IMPACT RESISTANCE AND COMPOSITE FORM THEREOF

摘要

PURPOSE: A composite form using a composite board having excellent impact resistance is provided to improve workability by lightening. CONSTITUTION: The composite form(30) using a composite board having excellent impact resistance comprises: a composite board(20) containing a composite material layer composed of stiffener and resins, an impact resistant layer piled on the composite material layer and composed of high impact resistant materials, a lightweight layer piled on the impact resistant layer and composed of lightweight foams, an impact resistant layer and a composite material layer piled on the lightweight layer in order, and a coating layer coated on the surface of the composite material layer; a longitudinal steel frame(31) covering and supporting around the composite board(20); and a steel stiffening rib(32) stiffening after connecting upper/lower members or right/left members to the steel frame(31).
