Abstract

본 발명은 105mm이상의 대구경 화포에서 사용하고 있는 금속(황동)탄피를 대체할 수 있는 복합재료로 구성된 연소성 탄피 및 그의 제조방법에 관한 것이다.The present invention relates to a combustible casing composed of a composite material which can replace a metal (brass) casing used in a large diameter canvas of 105 mm or more, and a manufacturing method thereof.

본 발명의 연소성 탄피는 종래의 금속탄피가 그 기능은 충분하게 발휘할지라도 취급, 회수, 재생하는 과정에서 인력과 자원의 낭비는 비경제적이고 화포 본래의 목적인 전투력 향상에도 많은 장애요인이 뒤따르는 문제점을 해결하였다.The combustible casing of the present invention solves the problem that the waste of manpower and resources is uneconomical in handling, recovering and regenerating the conventional metal casing even if its function is sufficient. It was.
