ASSESSMENT OF THE EFFECTS OF VOIDS ON SOME PHYSICAL, MECHANICAL AND DAMAGE MECHANICS PROPERTIES OF CARBON/POLYMERIC COMPOSITES

Résumé

The work synthesized in this paper focuses on the effects of voids upon some “conventional” mechanical characteristics of composites laminates (i.e. moduli, strengths) as well as on physical properties (i.e. C.T.E., moisture absorption). The reader will also be provided with a first analysis of the effects of voids upon mode I delamination (i.e. critical strain energy release rate). Lastly, owing to ultrasonic (US) absorption measurements, a criterion of void acceptability is tentatively settled. The underlying idea is to demonstrate that interrelating US absorption with void content and laminates mechanical behaviour should enable quality control costs  associated to testing of test pieces cured with structurally important parts  to be reduced by avoiding performing some of the mechanical and chemical tests.
