ResumoCrack-growth tests under zero-tension fatigue loading were carried out on a chopped strand mat and a glass-fabric-reinforced polyester resin. A compliance calibration technique was used to measure crack growth so as to overcome difficulties with visual measurement. The Paris (1957) power relationship based on stress intensity factor range was applicable to the results, but the value of the exponent was much greater than reported values for metals and polymers.
