Acoustic Emission Technique

The fracture mechanics response of oil palm and pineapple fiber reinforced phenol formaldehyde composites was investigated. The fracture behaviour was influenced by the fiber content, the length of the fibers and the condition of the fiber-matrix interface. Single edge notched tensile specimens were cut from composite plates and examined. The fracture toughness was determined from force-elongation curves. Tensile tests and acoustic emission investigations were carried out simultaneously. It was found out that the failure mode for untreated and treated materials was quite different. Scanning electron microscopy micrographs were taken from the fracture surfaces.
