粉末冶金法炭纤维/Mg复合材料的界面对其力学性能的影响
Effect of interface properties on the mechanical performance of carbon fiber/Mg composites fabricated by powder metallurgy
摘要
Abstract
Carbon fiber/magnesium composites were fabricated by powder metallurgy techniques using short carbon fibers electrolessly coated and uncoated by nickel as reinforcement and pure magnesium powder as matrix. SEM- EDS, TEM, XRD and tensile tests were used to characterize their interfacial morphology, elemental composition , phase composition and mechanical properties. Results showed that the carbon fibers were uniformly distributed in the composites and were preferentially oriented parallel to the extrusion direction. The interfacial bonding between carbon fibers and magnesium was improved by the nickel coating. The improvement was achieved by a reaction between the nickel coating on the fibers and magnesium to form Mg2Ni. The reinforcing effect of the nickel-coated carbon fibers was achieved by interfacial load transfer as evaluated by comparing the measured yield strengths with the theoretical values.关键词
