High-temperature off-axis fatigue behaviour of unidirectional carbon-fibre-reinforced composites with different resin matrices

A multiscale approach for fatigue life prediction of polymer matrix composite laminates

“…The fatigue failure criterion of equations (19) and (20) can detect different modes of failures at the micro level which include fiber failure in tension or compression, matrix failure in tension, compression and shear. Upon the occurrence of one of these modes of failures, the material loses its ability to sustain load in the direction associated with the failure; however, it can still bear load in other directions.…”

Woven ply thermoplastic laminates under severe conditions: Notched laminates and bolted joints

“…So far, however, there is a lack of available experimental data on the behavior of fabric reinforced PPS composites at high temperature. Around their glass transition temperature, the nonlinear behavior of fiber-reinforced composites becomes significant, especially under off-axis loading conditions [12,13]. This non-linear response, associated with the shear deformation of the polymer matrix along reinforcing fibers, is enhanced at high temperature due to the viscoplastic nature of the TP matrix [14,15].…”

Influence of temperature on the delamination process under mode I fracture and dynamic loading of two carbon–epoxy composites

“…The composite material's resistance to delamination depends on the magnitude of this adherence. Proper adhesion is thus essential to optimize the transmission of loads from matrix to fibers [5][6][7][8][9].…”
