We present a computational framework to explore the effect of microstructure and constituent properties upon fracture toughness fibre-reinforced polymer composites. To capture microscopic matrix cracking fibre-matrix debonding, couples phase field method cohesive zone model in context finite element method. Virtual single-notched three point bending tests on fibre reinforced composites are cond...

The translaminar fracture toughness is a key property that governs the damage tolerance and notch sensitivity of fibre-reinforced composites. Compact tension tests were performed to investigate composites reinforced with three types high-performance polymer fibres: polyarylate (PAR), polybenzobisoxazole (PBO) aramid fibre. A carbon fibre composite was used as reference system. propagation tough...

An impact fatigue study has been made for the first time on 63⋅5% glass fibre reinforced vinylester resin notched composites. The study was conducted in a pendulum type repeated impact apparatus especially designed and fabricated for determining single and repeated impact strengths. A well-defined impact fatigue (S–N) behaviour, having a progressive endurance below the threshold single cycle im...

The limitation of non-destructive methods for the inspection of carbon fibre reinforced plastic (CFRP) composites is a major problem for many practical applications of the material, especially in the aircraft industry. This paper presents a study which is directed towards non-destructive characterization of CFRP using eddy current methods. The relationship between the signal from different type...
