The Fatigue Behaviour of a Carbon Fibre Composite with Laminate Constructions of 0 deg, 0 + or - 45 deg and 90 + or - 45 deg.

Abstract

Fatigue tests have been made on plain specimens of O degree, O + or - 45 degree and 90 + or - 45 degree orientations of carbon fibre composite. The effect of holes and preconditioning by thermal ageing and humidity were studied with 0 + or - 45 degree and 90 + or - 45 degree laminates. S-N curves were obtained from all these tests and some fractured specimens were photographed. The results provide further confirmation that 0 + or - 45 degree CFC is notch sensitive to monotonic loadings but not to fatigue conditions. Prolonged ageing at 40 C and humidity exposure at 40 C and 95% RH had no significant effect on fatigue endurance. (Author)
