- Abstract
MC nylon is a vital engineering plastic that has been widely used. To address the shortcomings of MC nylon, such as poor strength under heavy load, poor dimensional stability and thermal stability, short-cut carbon fibers (SCF) is used as a modifier to explore the preparation process of SCF/MC nylon composites, investigating the effects of different SCF contents on the density, conversion rate, mechanical properties, friction properties and crystallinity of the composites. The results show that in the range of 0-20% SCF content, the density and tensile strength of the composites increase first and then decrease. The conversion rate and impact strength of 20%SCF are the most prominent. The coefficient of friction and wear extent showed decrease and then increase after the addition of SCF, the material showed good friction properties at 10% SCF content. The crystallization temperature of the composite increased to 182.95 °C and the degree of crystallization was 35.57% with 10% SCF reinforcement. The results confirm that the performance of MC nylon can be effectively improved by adding an appropriate proportion of SCF modifier, which is a beneficial attempt to further develop new composite materials to meet certain special spiral drives.
