본 발명은 저속 충격 보호를 위한 스티칭 전자기파 흡수 복합재에 관한 것으로서, 특히 전자기파 흡수체인 복합재에 두께 방향 보강법인 스티칭 공법을 적용하여 전자기파 흡수 성능과 동시에 저속 충격 보호 성능이 나타나는 복합재에 관한 것이다. 본 발명은 전자기파 흡수 복합재에 있어서, 유리섬유, 에폭시 또는 유리 섬유 강화 플라스틱(GFRP ; Glass Fiber Reinforced Plastics) 중 적어도 어느 하나 이상으로 구성된 복합재를 포함하고, 상기 복합재는 전자기파를 흡수하고 스티칭을 통한 충격 보호 시스템이 적용된 것을 특징으로 하는 저속 충격 보호를 위한 스티칭 전자기파 흡수 복합재를 제공한다.

    The present invention relates to a stitched electromagnetic wave absorbing composite material for low-speed impact protection and, in particular, to a composite material that exhibits electromagnetic wave absorption performance and at the same time, low-speed impact protection performance by applying a stitching process, which is a thickness-direction reinforcement method, to a composite material that is an electromagnetic wave absorber. The present invention provides a stitched electromagnetic wave absorbing composite material for low-speed impact protection, the electromagnetic wave absorbing composite material comprising a composite material composed of at least one of glass fiber, epoxy, or glass fiber reinforced plastics (GFRP), wherein the composite material absorbs electromagnetic waves, and has been subjected to the application of an impact protection system through stitching.
