Mechanical and Thermal Properties of Needle Punched Nonwoven Carbon/Phenol Composite

니들펀칭 부직포 탄소/페놀 복합재료의 역학적 성질 및 열적 성질에 관한 연구

The effect of punching density on the mechanical and thermal properties of nonwoven needle-punched carbon/phenol composite was studied. The carbonized preforms were farmed into composites with phenol resin. The interlaminar shear, tensile and flexural strengths were increased with increasing punching density. However, excessive punching density decreased interlaminar shear and tensile strengths. Erosion rate of carbon/phenol composite was decreased with increasing punching density
