Fiber-reinforced polymer-matrix composites have been widely applied in various areas due to their excellent mechanical properties. In this study, carbon fiber-reinforced polymer-matrix composites and glass fiber-reinforced polymer-matrix composites failure tests under quasi static torsion have been demonstrated by using spiral notch torsion test methodology. The global fiber kinking theory for the estimation of the axial compressive strength of a UD CFRP was modified for the local fiber kinking theory. Then, the nonlinear shear stress–strain curves of the composite and matrix were measured by the V-notched beam test, in-plane shear test, and torsion test.
Carbon fiber testing is a set of various different tests that researchers use to characterize the properties of carbon fiber. The results for the testing are used to aid the manufacturer and developers' decisions selecting and designing material composites, manufacturing processes, and for ensured safety and integrity.

THE IOSIPESCU SHEAR TEST FOR HYBRID FIBER COMPOSITES Jianmei He, Martin Y.M. Chiang, Walter McDonough and Donald L. Hunston . walled tube test and the solid rod torsion test [2,3], the Iosipescu shear test uses a flat specimen . volume fraction of epoxy matrix in glass and carbon fiber tows is the same as with the experiments at 30%, while . The type of carbon fiber material chosen in this paper is T700-12 K, and its density is 1.76 g/cm3. The matrix is JL-235 and JH-238 epoxy resin adhesive provided by Changshu Jiafa Chemical Company, with densities of 1.14 g/cm3 and 0.92 g/cm3, respectively. The epoxy resin has low viscosity and high fluidity. Carbon fiber-reinforced composites exhibit excellent mechanical properties for a variety of applications. Using the spirally notched specimens, we demonstrate how unidirectional carbon fiber-reinforced polymeric composite specimens with different fiber orientations fail under quasistatic torsion. By collecting data at 200,000 points per second, type I specimens . As the mechanical properties of carbon fiber are much higher than those of glass fiber . this area is more prone to shear failure in the torsion test. The undulated fiber bundles along the winding direction are compressed, leading to the gradual collapse of the internal matrix and the failure of fiber monofilaments under pressure. .
Carbon fiber reinforced composites are being increasingly used in applications requiring low weight with high strength and stiffness. In many widely adopted out-of-autoclave (OOA) processes such as vacuum infusion processing (VIP or VARTM) and resin transfer molding (RTM), carbon fiber fabrics are most commonly used for rapid laminate thickness .Deformation and failure of carbon fiber composite specimens with embedded defects during tension-torsion test. . .3221/IGF-ESIS.46.27 Deformation and failure of carbon fiber composite specimens with embedded defects during tension-torsion test Valery E. Wildemann, Tatyana V. Tretyakova, Elena M. Strungar, Mikhail P. Tretyakov Center of . Figure 4. 2 nd Hybrit drive shaft static torsion test. . To avoid potential risks, filament winding with integrated flanges was proposed to prepare carbon fiber-reinforced composite (CFRP) drive . To date, the characterization of mode I, II and their mixed-mode interlaminar (delamination) failure is of a great concern in classical fiber composites reinforced with carbon fibers [[5], [6], [7]] and glass fibers [8].Hosseini et al.
