Superior mechanical and tribological properties of short-cut carbon fiber reinforced monomer casting nylon composites after heat treatment

摘要

? 2023The effect of oil and water treatment with respect to the mechanical and tribological properties of short-cut carbon fiber (SCF)/monomer casting (MC) nylon composites was investigated. It was found that both the oil and water treatment can improve the crystallinity of SCF/MC nylon composites. The tensile strength and impact strength of oil treatment composites increase and the friction coefficient and the volumetric wear decrease. In addition, the water treatment is not as effective as oil treatment in improving material properties. This work would provide significant guidance for the preparation and post-treatment of SCF/MC nylon composites with excellent properties. It is also a useful attempt to develop new composite materials further to meet the needs of certain special spiral drives.
