Micromechanisms influencing crack propagation in a unidirectional sic-fiber (scs-8) continuously reinforced al-mg-si 6061 alloy metal-matrix composite (sic(sub f)/al-6061) during monotonic and cyclic loading are examined at room temperature, both for the longitudinal (0 deg or l-t) and transverse (90 deg or t-l) orientations. it is found that the composite is insensitive to the presence of notches in the l-t orientation under pure tension loading due to the weak fiber/matrix interface; ...
The obvious benefits of the design of aerospace structures using lighter materials with high specific strengths and stiffnesses had led to the development of numerous reinforced composite metallic and intermetallic materials, which have become serious commercial competitors to traditional monolithic metallic alloys. While significant advances in processing technology have made the fabrication of such hybrid materials more of an economic reality, their widespread use in airframes or other structures has ...
The obvious benefits of the design of aerospace structures using lighter materials with high specific strengths and stiffness has led in recent years to the development of numerous reinforced composite materials, which have become serious commercial competitors to traditional monolithic metallic alloys. While significant advances in processing technology have made the fabrication of such hybrid materials more of an economic reality, their widespread use in airframes or other critical structures ...
