초록
본 연구에서는 황마 단섬유 강화 폴리유산을 코어 폼으로 하고 연속 유리 섬유 강화 폴리유산을 외곽 스킨으로 하는 샌드위치 패널 구조의 황마 단섬유 강화 폴리유산 복합재료를 제작하였고, 황마 섬유 무게 비에 따른 복합재의 굽힘 특성을 관찰하였다. 코어 폼의 밀도는 0.31-0.67 g/cm3 기공함량비는 0.51-0.71이었다. 최대 굽힘 강도는 황마 섬유 무게비 12.5 wt.%에서 92.7 MPa, 최대 굽힘 탄성계수는 황마 섬유 무게비 30.0 wt.%에서 7.58 GPa으로 측정되었다. 경제성 분석을 실시했으며 적용 부재의 굽힘 강도를 향상시키기 위한 비용은 황마 섬유 무게 비가 12.5 wt.%일 때 0.010 USD/m3/MPa로 계산되었다.
Abstract
In this study, we fabricated jute fiber reinforced polylactic acid (PLA) composite in the form of sandwich panel structure which includes core foam of chopped jute fiber reinforced PLA and outer skin layer of continuous glass fiber reinforced PLA. Flexural properties of the composite were assessed for different jute fiber weight fractions. Density of the core foam ranged from 0.31 to 0.67 g/cm3 and void content fraction 0.51 to 0.71. The maximum flexural strength was 92.7 MPa at 12.5 wt.% of jute fiber content, and the maximum flexural modulus was 7.58 GPa at 30.0 wt.%. Cost analysis was also conducted. The cost to enhance the flexural strength of the applied structure was estimated to be 0.010 USD/m3/MPa for 12.5 wt.% fiber content.
