초록
최근 플라스틱 폐기물로 인한 환경오염, 미세플라스틱의 생태계 교란 및 인체축적이 큰 문제로 떠오르고있다. 이를 대체하기 위하여 친환경 수지 및 천연섬유 기반의 복합재료가 개발되어 왔으나 합성섬유 기반의 복합재료에 비하여 기계적 물성이 크게 떨어진다는 단점이 있다. 본 연구에서는 천연섬유인 황마섬유(jute fiber)의 기계적 물성을 향상시키기 위하여 해초로부터 친환경 나노섬유를 추출 후 첨가제로 사용하였다. 핸드 레이업 공정을 이용하여 복합재료를 제조하였으며, 인장, 굽힘, 낙추충격시험을 통하여 나노섬유가 천연섬유 복합재료의 기계적 물성 향상에 효과적임을 확인할 수 있었다.
Abstract
Recently, environmental pollution caused by plastic waste, ecosystem disturbance of micro-plastics and human body accumulation are becoming big problems. In order to replace the traditional plastic, eco-friendly resin and natural fiber-based composite materials have been developed, but they have a disadvantage that their mechanical properties are significantly lower than those of synthetic fiber-based composites. In this study, eco - friendly nanofiber was extracted from seaweed and used as an additive in order to improve the mechanical properties of jute fiberreinforced composites. Through the hand lay-up process, the composites were fabricated, and it was confirmed that the nanofiber was effective in improving the mechanical properties of natural fiber composites through tensile, bending and drop weight impact tests.
