Purpose: The aim of the work was to find relationships between the selected parameter of an ultrasonic wave and the local fibre content in a glass/epoxy composite. Design/methodology/approach: The experiments have been performed in two distinct phases. During the first phase, typical glass/epoxy composite materials with different fibre content were examined by means of through-transmission and pulse-echo ultrasonics. In the second phase, the standard destructive method was applied to determine the actual glass content in investigated composite materials Findings: The experimental results showed relationships between ultrasonic wave velocity and the local fibre content in investigated composite materials. This study has also assessed the ability of pulse-echo technique to carry out such a testing. Research limitations/implications: Relationships found may be useful to local fibre content examination, but for each composite material different relationships are required to be determined, as was done in the present study. Practical implications: The described method can be applied to the post-production quality control of a finished composite product, but in the case of composites made of different components it is necessary to determine distinct relationships for each material. Originality/value: A new approach to the problem of fibre content examination has been demonstrated by means of pulse-echo technique. The method developed should be of interest to the industrial quality control procedures and has great importance for products with a high failure-free requirements.
