The present engineering sector focused on the sandwich composites and almost covered all engineering fields because of decent mechanical properties with a lightweight structure. It mainly consists of high strength fiber skin and porous structure core like corrugated, honeycomb, balsa wood, and foams which is playing a pivotal role in weight reduction. Recently researchers attention grabbed by Natural fiber sandwich composites due to biodegradability, renewable, low-cost, and environmentally friendly. However special focus is highly needed towards the flammability behavior of natural fibers used as reinforcement for composites. Herein, for the first time, the flame retardant natural fiber sandwich composite was fabricated by using flame retardant treated bamboo fabric and vinyl ester via the VARTM process. The impact of flame retardant treated bamboo fabric on mechanical and flame retardant properties were studied. The results concluded that the fabricated bamboo sandwich composites show structurally lightweight with significant mechanical strength and feasibility with respect to the flame.

샌드위치 구조는 우수한 강도와 경량성을 동시에 만족하는 구조물로써 다양한 분야에서 널리 사용되고 있다. 스킨은 주로 고강도의 섬유가, 코어는 경량화에 유리한 허니콤 구조 및 발사(balsa) 나무가 주로 사용되고 있으나, 내부의 공기층 및 난연처리의 어려움으로 인하여 화재에 취약하는 것이 단점이다. 본 연구에서는 대나무 섬유의 난연처리 연구를 통하여 친환경적인 소재를 이용한 난연처리 조건을 제시하였다. 또한 대나무 섬유를 이용하여 천연섬유 샌드위치 복합재료를 제조하고 기계적 특성평가를 수행하였다. 난연성이 향상된 천연섬유를 이용하여 샌드위치 구조의 복합재료를 제조한다면 새로운 유형의 복합재료가 될 수 있을 것으로 기대된다.
