ジャーナル フリーThe aim of this contribution is to give the procedure of the digestion method for the determination of fiber content of metal matrix composites. In order to discuss the method, silicon carbide whisker reinforced aluminum alloys were digested by some solutions. The suitable acidic or basic solution to digest the matrix and the procedure to clean the collected fiber depend upon the chemical characteristics of the fiber and the matrix. Some alloying elemets in the matrix are insoluble in the digestion solutions. And some fragment of the fiber may pass through the filter to collect the fiber. Accordingly, it is not enough to correct for the weight loss of the fiber by the digestion procedure, as ASTM D 3553. But these are also necessary to correct for the insoluble-filtered fraction in the matrix and to correct for collecting efficiency of the fiber by the filter. The opening size of the filter to collect the fiber should be determined from the size of the fiber diameter or fragment in the composite being tested. The used silicon carbide whisker is oxidized in dry air below 400°C accompanied by a weight increase. For the precise determination of the fiber content of metal matrix composites by digestion method, corrections should be done for the insoluble-filtered fraction in the matrix and the weight change of the fiber during the procedures of digestion, filtering and drying.抄録全体を表示PDF形式でダウンロード (1967K) -

ジャーナル フリーInterlaminar toughness which is generally treated as a material constant is used as a quantity to express strength or toughness of the interlaminar region of composite laminates. As discussed by many researchers, the fracture toughness of the material depends on the fracture modes or process, that is, on the mechanism of the failure. So, the interlaminar toughness of composite laminates may depend on the inclination of the delamination propagating direction to the fiber even in the same mode fracture, because the micromechanical failure process at the delamination front may differ due to the differences of the micro-mechanical structures and the stress distributions at the neighborhood of the delamination front. In the present paper, mode I fracture toughnesses GIC of a carbon fiber woven composite are measured about various inclinations of delamination propagations to the fiber direction and its dependence on the inclination angle are investigated.抄録全体を表示PDF形式でダウンロード (6544K)
