Measurement of multiple mechanical properties for polymer composites using digital image correlation at elevated temperatures

In situ investigation of failure in 3D braided SiCf/SiC composites under flexural loading

“…Nonetheless, the analysis allow the effect of mechanical damage on the specimen compliance to be monitored through its effect on curvature. This method has been applied successfully in flexural tests of polymer composites [52], C/C-SiC composites [46], and alumina-alumina composites [53]. Moreover, this approach, which provided data also on the position of the neutral axis, has potential use as a means to verify numerical simulations of damage development.…”

Integrated digital image correlation for mechanical characterization of carbon fiber-reinforced polymer plates

“…reviews [5,6]. DIC has been previously used for characterizing multiple CFRP linear-elastic material properties [7], and also their temperature dependence [8], using a finite-element-model-updating method and short-beam shear experiments. Herein, we propose to characterize multiple material properties using simpler tension/compression experiments, and also to capture tension/compression asymmetry, by employing an inherently more robust DIC technique.…”

Experimental investigation on thermomechanical behavior of glass fiber reinforced polymer composites

“…[3][4][5][6] The thermoset epoxy resin is widely used as a matrix in many fiber-reinforced composite materials. Epoxy composites play a vital role [7][8][9] in structural application because they provide balanced chemical and mechanical properties. GFRP plays a critical role as an alternative base for numerous strong, unconventional materials in many engineering applications.…”
