초록

By alternating $Al_{18}B_4O_{33}$/AC4CH composites with Al1050 sheets and then hot pressing, MMC/Al laminate composites have been successfully fabricated as parameters of the laminate structure and the number of Al sheet. Impact properties for laminate composites have been evaluated both in the laminate structure and in the impact load direction. Lamination of Al sheet and MMC layer showed a remarkable improvement in the absorbed impact energy compared to that of monolithic MMC. Laminate composites mounted with Al sheet at the outside of the configuration had a higher impact energy in the edge wise compared to that with Al sheet at the inside. Furthermore, there was an anisotrpy in the impact value of laminate composites, that is, impact values for the flat wise in a constant volume fraction of Al sheet dramatically increased along with Al sheet number, even if impact values fur the edge wise were nearly constant.
