Method for inspecting faults appearing in a composite carbon fibre material by perforation of the pocket during the production process

The method involves removing pocket which surrounds a part after drying, and placing an infrared camera (102) and lamps (103) for heating a material through light pulse (109) in front of an infrared thermography test (101). The test is heated through the lamps, and the evolution of temperature of a surface of the specimen during its heating and cooling, is captured through the camera, where data is transferred to a computer (104). Presence of defects is determined by occurrence of contrast on thermogram in digital values, temperature values or in temperature contrast values.
