The present invention relates to a stitched composite material absorbing an electromagnetic wave, for impact protection at a low velocity and, more specifically, to a composite material having both an electromagnetic wave absorbing performance and a low-velocity impact protection performance as a stitching method which is a thickness direction reinforcing method is applied to the composite material which is an electromagnetic wave absorber. The composite material absorbing the electromagnetic wave, for the impact protection at the low velocity, includes a composite material comprising glass fiber, epoxy, or glass fiber reinforced plastics (GFRP). The composite material absorbs the electromagnetic wave and is applied with an impact protection system using stitching.

    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.
