In this paper, the different mechanisms that can be used to reinforce laminated ceramic coposites were reviewed in two parts at macroscopic scale. Furthermre, optimum design of such composites was briefly pointed out, and as an exaple, the fracture toughness was optimized by discussing the effects of changes in specimen variables, including lamina strength interface bonding strength as well as interface and lamina thickness in de- Key words laminate composite, ceramic fracture, toughening, strengthening, optimum design )01994-2009ChinaAcademicJournalElectronicPublishingHouse.aLlrightsreservedhttp:/www.cnki.net13 Hui Wang , Xiaozhi Hu1 J1Am1Ceram1Soc1 , 1996 , 79 ( 2) : 553 14 Oechsner M , C Hillman , Lange F F1 J1Am1Ceram1Soc1 , 1996 , 79 ( 7) : 1834 15 Lakshminarayanan R , Shetty D K1 J1Am1Ceram1Soc1 , 1996 , 79 ( 1) : 79 16 Prakash O , Sarkar P , Nicholson P S1 J1Am1Ceram1Soc1 , 1995 , 78 ( 44) : 1125 17 Yaroshenko V , Orlovskaya N , et al1 Key Engineering Materials , 1997 , 1322136 ( Pt 3) : 201722020 18 郭景坤 , 诸培南 1 硅酸盐学报 , 1996 , 24 ( 1) : 7 19 Phillipps A J , Clegg WJ , Clyne T W1 Acta metall1mater , 1993 , 41 ( 3) : 805 20 杨 辉 , 葛曼珍等 1 ν 材料加工和研究进展 µ , 第二卷 1 化工出版社 , 1996 , 5 : 236 21 Ashok D B Salagame R R1 Microcomputers in Civil Engineering , 1995 , 10 : 301 22 Kalamkarov Alexander L1 ASTM Special Technical Publication v 1309 Mar 19971ASTM , Conshohocken , PA , USA12372 249 Reinforcement Mechanisms and Optimum Design of Laminated Ceramic Composites QIAN Xiao2Qian ­ GE Man2Zhen WU Yi2Bing YANG Hui ( Department of Civil Engineering ­ Department of Materials Science & Engineering , Zhejiang University Hangzhou 310027 China) Abstract Laminated ceramic composites which have a unique structure , have been used in tailoring the microstrucure and mechanical properties of structural ceramics, and it is shown that both strength and toughness can be im2 proved 1In this paper , the different mechanisms that can be used to reinforce laminated ceramic composites were reviewed in two parts at macroscopic scale 1Furthermore , optimum design of such composites was briefly pointed out , and as an example , the fracture toughness was optimized by discussing the effects of changes in specimen variables, including lamina strength , interface bonding strength , as well as interface and lamina thickness in de2 tails 1 Key words laminate composite , ceramic fracture , toughening , strengthening , optimum design 526 无 机 材 料 学 报 14 卷
