Micromechanisms of Fracture and Hygrothermal Aging of Fibrous Composites.
Abstract
The micromechanisms of crack extension of carbon fibres, glass fibres, and hybrid composites containing glass fibres and carbon fibres in epoxy and polyester resins have been studied. A new collection of failure data has been summarized in cumulative probability diagrams and analysed using Weibull distribution parameters. This data, together with models of failure processes and information of work of fractures, is used to construct fracture-mechanism diagrams. These diagrams, together with the Weibull parameters may help in distinguishing between mechanisms of fracture; give guidance in selecting a material system; and in isolating aging and environmental effects.
