APPLICATION OF LASER-ULTRASONIC METHOD FOR TESTING OF INHOMOGENEITIES OF POLYMER MATRIX DISTRIBUTION IN CARBON FIBER REINFORCED PLASTIC CONSTRUCTIONS
(pp. 48-53)

Abstract. Carbon fiber reinforced plastics (CFRP) are currently widely used in industry. Such materials can have some inhomogeneity of polymer matrix distribution and inaccuracy of carbon fiber laying. The aim of this work is detection of manufacturing defects in CFRP structure using laser-ultrasonic method and quantitative evaluation of volume concentration of matrix and filler. This method allows generate of short and power probe acoustical pulses in wide spectral range from tenths of MHz to tens of MHz. The distributions of volume concentrations in the selected areas of the composite structure are obtained. It is shown that in this construction there are areas with both excess and deficiency of epoxy matrix. The images of manufacturing defects, which is gaps between the strips of carbon tissue, are obtained. This analysis allows searching potential vulnerable parts of composite structure, because areas with such gaps have lower strength in comparison with defectfree areas. Proposed method may be used for quality monitoring of composite structure before exploitation.

Keywords: carbon fiber reinforced plastics, stringer panel, laser-ultrasonic method, longitudinal ultrasonic wave.
