Fracture behaviour of hybrid glass matrix composites: thermal ageing effects

Mechanical properties of hybrid composites prepared by ice-templating of alumina

“…This observation is closely linked to the determination method, fracture toughness using chevron notch technique measure usually some point at the beginning of R-curve. This method was successfully used previously and it was found more reliable for composite systems than other methods [22][23][24]. Moreover, the values obtained here are in good correlation with the literature data [9,25].…”

A status report on delamination resistance testing of polymer–matrix composites

“…The evaluation of effects of environmental exposure on fracture mechanics data has to be evaluated also, in particular if fracture mechanics data are used in the design of composite parts or structures [3]. Ageing effects from thermal cycles (e.g., [96]) or water exposure (e.g., [97][98][99]) on quasi-static behavior can quite likely be assessed by testing suitably exposed specimens in a standard laboratory climate. Fatigue delamination growth at elevated temperatures has been investigated for example by Sjögren and Asp [100].…”

The Effect of Thermooxidative Aging on the Durability of Glass Fiber-Reinforced Epoxy

“…A considerable amount of literature concluded that chemical shrinkage [23,25,26,[62][63][64][65] or notable variations in the matrix and fiber thermal expansion factors [36,66] may provide dilatational stresses (internal stresses) or synergistic effects of both. In addition, in morphological investigations, fiber-matrix interfacial adhesion also degraded and weakened as a result of moderate heat exposure [3,[67][68][69], resulting in fiber pullout failures as part of the fracture mode [70][71][72][73].…”
