Purpose: The primary purpose of the present study was to find relationship between ultrasonic wave velocity and the fiber content in glass/polyester composites. In addition, further tests were conducted to determine how other factors can affect the ultrasonic velocity. Design/methodology/approach: Experimental data have been obtained using ultrasonic wave velocity measurements and standard destructive analysis. For ultrasonic non-destructive testing, through-transmission technique was used. Findings: Experimental results have shown that the longitudinal wave velocity increases almost linearly with an increase of the fiber content in investigated specimens. Research limitations/implications: The propagation velocity of the ultrasonic waves can be affected, apart from fiber content, by interfacial stresses and changes of elastic modulus in polymer matrix during long-lasting conditioning. These factors overlap and which of the two can affect the ultrasonic wave to a higher degree is yet to established. Further work is needed in this area. Practical implications: Ultrasonic wave velocity measurement seems to be an effective method of fiber content evaluation, but for any different composites, distinct relationships should be determined. Originality/value: The results obtained would be of considerable importance in industrial applications to achieve a first estimate of fiber content variations in composite materials.
