Abstract

Fiber breakage during consolidation processing is a significant problem which leads to a reduction in the composites strength in the axial and transverse direction. Past research and development projects have been restricted to measurement of fiber fracture after consolidation and to modeling the process during the consolidation cycle, however, no direct or indirect method has been developed to measure fiber breaks during the consolidation. This method successfully incorporates acoustic emission sensor technology capable of measuring fiber breaks inside of a hot isostatic press during the consolidation of metal matrix composites.
