The optimized temperatures of preform, Tf, for bare or PCS SiC-coated C fibres and of molten metal, Tm, Al-10Si matrix seem to be matched by 733 K and 1033 K or 753 K and 1053 K respectively. The quality of interface in composites is different from the coating of C fibres. Such coating, either to retard the interfacial reaction or to better the bonding state, may improve the strength of composites, e.g., increase of strength of a composite up to 89% by PCS SiC-coating and also improvement of wettability by K2ZrF6 solution. The strength of composites increases with the increase of the interfacial shear stress. Furthermore,the optimized shear stress of M40/Al composites with high modulus C fibers is higher than that of the CF/Al composites with low modulus fibers, thus the higher tensile strength was obtained.Correspondent: WANG Yuqing,(associate Professor, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110015) Key words:  C_F/Al composite      interface      technological parameter      coating      strength      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I14/86 1CoorCR,YunDI,HuntJrWH．inFishmanSGed．,CastReinforcedMetalComposites,ASM,1988:1952ZhangGD,ZhangWD．ProceedofICCM//Ⅷ,USA,Hawsaii,1991:19H3张国定．航空学报,1991;12:B5704WangYuping,ZhouBenlian,WangZouming,ShiChangxu,JMaterSciTechnol,1993;97:75 王玉庆,郑久红,周本濂．金属学报,1994;30:B1946 王玉庆,王作明,刘 敏,周本濂,师昌绪．复合材料学报,1992;9:137 RocherJP,QuenissetJM,NaslainR．JMaterSciLetter,1985;4:1527 [1] WANG Lei, LIU Mengya, LIU Yang, SONG Xiu, MENG Fanqiang.
