The synthetic lumber which administers metal material reinforcement

摘要

(57) Abstract Objective While utilizing the merit of the former synthetic lumber, the faultWhen it supplies, decreases especially the coefficient of linear expansion simultaneously, it is the waTo raise the mechanical strength for seeing and breaking etc, the structural material in additionThe synthetic lumber which it tries to be able to utilize as the materials for construction stoppingIt offers. Constitution Extrusion inside foaming plastic 1 where it formed, that pushingInterior to do plate shaped metal stiffener 2 according to coming out direction, the said foaming combinationConnecting forming resin 1 to firm on the inside and outside surface of metal stiffener 2, formingru. The above-mentioned metal stiffener foaming plastic 1 of 2 and the inside and outside surface sideWith connecting line facilities to do the many hole 3 in the said metal stiffener 2, the soThrough each hole 3 of the re and others the foaming synthetic tree of both sides of metal stiffener 2It does by connecting unifies fat 1. With thatMetal stiffener connecting strength of 2 and foaming plastic 1 increases.
