The failure modes (such as fibre breakage, matrix damage and delamination)of Boron reinforced aluminum composite materials were studied at NAL through power spectrum analysis of AE waves. Tensie tests were conducted for four types of specimens of composite materials (unidirectional, 0度/90度 ply, boron fiber and shear lag test pieces), and for two types of specimens of 6061 aluminum alloy (tensile and shear test pieces). The results are summarized as follows : (1)Fiber breakage mainly relates to the AE wave characteristics in the low frequency range from 100 to 200 kHz. (2)Matrix damage and delamination mainly relates to the AE wave characteristics in the high frequency range from 400 kHz to 1 MHz. (3)The tensile and shear fracture of 6061 aluminum alloys relates to the AE wave characteristics in higher frequency ranges.
