Numerical simulation for strain rate and temperature dependence of transverse tensile failure of unidirectional carbon fiber-reinforced plastics

Abstract

In the present study, strain-rate and temperature dependence of the transverse tensile failure mode of unidirectional heat-resistant carbon fiber-reinforced plastics is numerically simulated by finite element analyses. In the analyses, interface failure and matrix failure are represented by cohesive zone modeling and continuum damage mechanics, respectively. For the continuum damage mechanics, Christensen's failure criteria of multi-axial stress states for each strain rate are applied to the matrix properties. Interfacial properties which are obtained by microbond test are introduced into cohesive zone modeling. A time-temperature superposition principle approach is applied in order to translate the difference in temperature as the difference in strain rate. The damage initiation depends on strain rate and temperature, while the cohesive zone modeling is assumed to be temperature- and time-independent. The initial damage starting points and the failure mode are predicted in numerical analysis. The transverse tensile strengths in analysis results are compared with the three-point bending testing results.

The Effect of Temperature and Strain Rate on the Interfacial Behavior of Glass Fiber Reinforced Polypropylene Composites: A Molecular Dynamics Study

“…The snapshots of the deformation of the glass fiber/PP material system at the final strain of 100% under various strain rates are shown in Figure 15. It was reported that the transverse tensile failure mode of unidirectional CFRTCs changes from matrix failure-dominant mode to interface failure-dominant mode with an increase of applied strain rate [37,38]. Our simulation results obtained the same conclusion.…”

Numerical Study on the Effect of Matrix Self-Heating on the Thermo-Visco-Plastic Response of Continuous Fiber-Reinforced Polymers under Transverse Tensile Loading

“…Maligno et al [ 15 ], Totry et al [ 16 , 17 ], Segurado and Llorca [ 18 ], and Vaughan and McCartney [ 19 , 20 ] also included the effect of thermal residual stress generated during the production process. The influence of strain rate is investigated by Sao et al [ 21 ] and Shafiei et al [ 22 ]. Arteiro et al [ 23 ] investigated the effect of neighboring plies on the damage development inside a central ply.…”

“…Arteiro et al [ 23 ] investigated the effect of neighboring plies on the damage development inside a central ply. Jordan et al [ 24 ], Sato et al [ 21 ], and Bai et al [ 25 ] included the effect of temperature on the macroscale behavior. This is done by including a temperature dependency in the constitutive equations of the matrix material.…”

Effect of high temperature on mechanical properties and porosity of carbon fiber/epoxy composites

“…A resume of literature reveals that the effect of temperature on the mechanical properties of carbon fiber/epoxy composite materials has been studied by various previous investigations. 1,[5][6][7]10,13,14,21,[25][26][27][28] The fundamental mechanical properties including tensile, compression, and shear tests have been experimentally investigated. Prior research indicates that the temperature sensitivity of carbon fiber/epoxy composite materials highly depends on the resin properties, reinforcement type, fiber distribution directions and performance of fiber-matrix interfaces.…”
