WebIn contrast, crack growth in fibre–polymer composites and ceramic aerospace materials (such as heat shields) occurs with less ductility and therefore is a more brittle fracture process. This chapter considers the mechanisms of ductile and brittle fracture of aerospace metals and the brittle fracture of fibre–polymer composites. WebBrittle Fracture. Brittle fracture is an unstable failure process that occurs in fibre–polymer composite materials, metals with high strength and low ductility, and in some metal types at low temperature (i.e. below the ductile/brittle transition temperature).
