摘要: Abstract In this study, long-period-stacking-ordered (LPSO) phases were introduced to carbon fiber reinforced magnesium-gadolinium-zinc (Cf/Mg-Gd-Zn) composite by adding Gd and Zn with the atomic rate of 2:1 into matrix, a new practical method design optimize interfacial structure was found. The Cf/Mg-Gd-Zn fabricated pressure infiltration method, influence LPSO on microstructure mechanical properties investigated. precipitated both at interface in matrix. long rod-like, whose preferential growth direction almost perpendicular axis fibers. But formed matrix tended be short arranged certain angle adjacent fiber. Because phases, composites significantly optimized. Therefore, improved considerably. Specifically, compared Cf/Mg composite, interlaminar shear strength bending 26.4% 25.7%, respectively.
