Description

차량용 파티션 패널{PARTITION PANEL FOR VEHICLE}Car Partition Panel {PARTITION PANEL FOR VEHICLE}

본 발명은 코어층에 불연속 섬유를 포함하여 제조 원가가 낮고, 표면층에 연속 섬유를 포함하여 비틀림시 최대변형량이 낮아 강성이 우수한 차량용 파티션 패널에 관한 것이다.The present invention relates to a vehicle partition panel having excellent rigidity, having a low manufacturing cost by including discontinuous fibers in a core layer and having a low maximum deformation during twisting by including continuous fibers in a surface layer.

최근 차량의 연비 향상 및 제동거리 단축을 위해 차량에 적용되는 부품의 경량화가 주목받고 있다. 한편, 차량용 파티션 패널은 차량의 트렁크룸과 실내를 구분하기 위해 적용되는 부품으로서, 종래 차량용 파티션 패널은 금속 재질로 형성되었다. 이에, 차량의 경량화를 위해 파티션 패널의 소재로 금속 재질을 대신하여 연속 섬유 및 수지를 포함하는 복합재가 제안되었다. 제안된 복합재로 구성된 파티션 패널은 금속 재질로 이루어진 파티션 패널과 비교하여 강도 및 강성이 우수하거나 동등하면서 무게가 가볍다는 장점이 있다.Recently, in order to improve the fuel efficiency of the vehicle and shorten the braking distance, weight reduction of components applied to the vehicle has been attracting attention. On the other hand, the vehicle partition panel is a component applied to distinguish between the trunk room and the interior of the vehicle, the conventional vehicle partition panel is formed of a metal material. Accordingly, in order to reduce the weight of a vehicle, a composite material including continuous fibers and resins instead of a metal material as a partition panel material has been proposed. The partition panel composed of the proposed composite material has the advantages of being superior in strength and stiffness to the partition panel made of metal or equivalent weight and light weight.

그러나, 상술한 바와 같이 연속 섬유를 포함하는 복합재는 비싼 재료비로 인해 상기 파티션 패널의 양산성을 저하하는 단점이 있었다.However, as described above, the composite material including the continuous fiber has a disadvantage of lowering the mass productivity of the partition panel due to the expensive material cost.
