초록

In recent years, the range of the composite materials' use for the making lightweight in the fighter, high-speed train, and car body have increased. Among them, fabric CFRP composites are being used as primary structural components in many applications because of their superior properties. However, the complexity of the fabric structure makes understanding of their failure behavior very difficult. Crack propagation of plain woven carbon fiber fabric laminate composites are examined by acoustic emission(AE) method. Thus, the relationship between AE signal and crack extension length are shown for several initial crack length. Also the interlaminar fracture toughness in terms of AE characteristics is discussed in viewpoint of crack propagation behavior.
