TOUGHENING OF IN SITU SYNTHESIZED MoSi2-SiC COMPOSITE AT ROOM TEMPERATURE J.Zhu1,L.Q.Zhang2,Z.Q.Sun3,X.W.Fu2,W.Y.Yang2 (1.School of Materials, Tsinghua University, Beijing 100083, China;2.School... that the interfacebetween MoSi2/SiC is of direct atomic bonding without any amorphous glassy phase,such the SiO2 structure. Based on the fractography and the observation of crack prop-agation path from indentation......
used to enhance the toughness of epoxy resins is to add a softer second phase to epoxy resin[15]. The dispersed rubber phase plays an important role in the toughness improvement of the material. Rubber... in Figs.5(c) and (d). From the above results it can be inferred that H2O-NMe2 the toughening agent has been incorporated into the tight epoxy resin network and led to the formation of a two-phase......

Study on T700/Cyanate/PS/Epoxy Composites with ex-situ Toughening Technique郑亚萍1,WANG Hao2,ZHANG Jiaoxia3,XU Yahong4,DAI Feng4,WANG Jihui21. Department of Applied Chemistry, School of Natural...-situ toughening technique. The dynamic parameters of cyanate/epoxy resin were studied by differential scanning calorimetric(DSC) analysis and dynamic mechanical analysis(DMA). Microstructual toughening......
them, but few dislocations appear around the reticular second phase in the Mg–1Ce alloy. Among the three alloys, two internal friction peaks(P1 and P2) are detected at about 78 and 167?C in both the Mg–0.5Ce and Mg–1Ce alloys.In addition, the alloy with special parallel second phase structure exhibits excellent damping capacity in both strain amplitude and temperature-dependent regions. These results......
