Specifically, the shape of the ball layer is pre-processed using a press die, and then a fiber reinforced plastics (FRP) / rubber, plastic, or metal material, which is an outer material, is fixed on a fixed shaft die of the press die. The present invention relates to a composite material for automobiles, which is manufactured by placing a fibre-reinforced plastic (FRP), which is a ball layer / envelope, and pressing them.
20세기 초에 개발된 자동차는 그 수요가 폭발적으로 증가하여 현재에는 없어서는 안될 주요한 교통수단이 되었다. 그러나, 폭발적인 자동차의 증가에 비해 자동차의 에너지원인 석유의 매장량은 한정적이어서 향후 심각한 사회문제로 대두될 우려가 있으며, 그로 인하여 자동차의 대체 에너지 개발과 자동차의 경량화에 대한 연구가 활발히 진행되고 있다.Developed in the early 20th century, automobiles have exploded in demand, making them a major means of transportation nowadays. However, in comparison with the explosive increase of automobiles, the reserves of oil, which is an energy source of automobiles, are limited, which may pose a serious social problem in the future. Therefore, research on the development of alternative energy of automobiles and lightweighting of automobiles is being actively conducted.
이제까지 자동차의 섀시 등에 사용되었던 스틸재를 알루미늄 합금 또는 복합재(composite materials; CM) 등의 재료로 대체하여 자동차를 경량화하려는 연구가 계속되고 있다.Research into lightening automobiles is being continued by replacing steel materials, which have been used in automobile chassis and the like, with materials such as aluminum alloy or composite materials (CM).
기존에 자동차용 구조재로 사용되었던 복합재인 허니코움 보드(honey-comb board)는 강화 플라스틱 등으로 제조된 판과 판 사이에 두꺼운 종이 또는 얇은 금속판으로 제조된 육각형의 벌집 구조물인 허니코움 구조물(honey-comb structure)을 넣고 접착 또는 압착시켜 제조하였다. 이러한 허니코움 보드는 경량이며, 압축 및 굽힘강도가 크지만, 강화 플라스틱 판재에 허니코움 구조물을 접착시키기 때문에 대량생산이 불가능하고, 굽힘강도가 커서 가공이 원활하지 못하다는 단점이 있다.Honeycomb board, a composite material that has been used as a structural material for automobiles, is a honeycomb structure that is a hexagonal honeycomb structure made of thick paper or thin metal plate between a plate made of reinforced plastic and the like. comb structure) was prepared by bonding or pressing. Such honeycomb boards are lightweight, have high compression and bending strength, but cannot be mass-produced because they adhere the honeycomb structure to the reinforced plastic sheet, and have a large bending strength, so that processing is not smooth.
