    CRP/GRP laminated plates of the canapé construction was investigated on the flexural properties and the fracture behaviors. CRP/GRP laminated plates had two types (CRP-1-ply/GRP-15-plies and CRP-2-plies/GRP-13-plies) in which the ratio of the thickness of CRP to that of GRP was varied at the constant total thickness of the two types. And the structural merit of the canapé construction was discussed according to the flexural properties of the components, constituting CRP/GRP laminated plates. CRP/GRP laminated plates of two types did not vary in the flexural properties. However, it was observed that the fracture behaviors differ in the two types, that the canapé construction of CRP-1-ply showed the toughness, and that the other showed the brittleness. Comparing with the flexural properties of only GRP, the modulus of elasticity in bending of CRP/GRP laminated plates was improved 44∼61 percent, and the yield point and the flexural strength were also improved 43 percent and 15∼24 percent, respectively. Especially, the modulus of elasticity in bending and the yield point were exceedingly improved, therefore, these results showed the excellent effectiveness of the canapé construction.

    Pb-Al2O3 composites containing 3.2, 5.1 and 7.4 vol % Al2O3 (1μ) were made by mechanical alloying process, followed by compacting and extruding, to improve the mechanical properties of lead. Creep property of Pb-Al2O3 composites was evaluated through the creep test in the range of temperature 160°C to 240°C. Effect of Al2O3 volume fraction on minimum creep rate was estimated and also steady state creep equation was derived.

    Pb-Al2O3 composites containing 1.8, 3.2 and 5.1 vol% Al2O3 (1μ) were made by mechanical alloying process, followed by compacting and extruding, to improve the mechanical properties of lead. The evaluation of tensile property of Pb-Al2O3 composites was performed through the tensile test in the range of strain rate from 0.7×10-2 to 2.1×10-2s-1. The contribution of Al2O3 volume fraction and strain rate to the flow stress was also discussed.
