Meso Scale

The yarn/yarn and yarn/matrix interface debonding has been recognized as a vital failure mode of 3 D braided composites. We present in this paper a meso-scale finite element (FE) model, which considers yarn/yarn and yarn/matrix interface debonding, for modeling progressive damage evolution of 3 D braided composites under typical tensile and shear loadings. In this setting, the damage state of braiding yarns and matrix is described through a continuum damage model (CDM) coupled with Murakami damage tensor; a bilinear traction-separation description is employed to govern the yarn/yarn and yarn/matrix interface behavior modeled by surface-based cohesive contact. We thus develop a user-material subroutine VUMAT (ABAQUS/Explicit) for our progressive damage simulation, including stress analysis, failure analysis and material properties degradation scheme. The mechanical properties of 3 D braided composites, and more importantly the damage evolution of interface debonding are thoroughly analyzed. The proposed FE modeling strategy provides a new perspective for the interface response study of other textile composites.

Mechanics Performance

Defects might be formed within braided composites because of the special production process and would have negative effects on the mechanics performance of 3D braided composites. It is important to test and analyses defects to take preventive measures for preventing their formation. In this paper, defects of 3D braided composites were analyzed and methods of nondestructive testing were introduced. Ultrasonic nondestructive testing is one of the earliest methods of nondestructive testing used to evaluate composites. Ultrasonic nondestructive tests of 3D 5-directional braided composites were carried in this paper and the characteristics values were extracted by wavelet analysis method and defect qualitative analysis was implemented.

The Matrix

The matrix representation of space point group is used in transferring the elastic matrix of the braided yarn based on the symmetries of braided composites representative volume element (RVE) meso-geometrical structure. The off-axis elastic matrixes of the whole braided yarns of the RVE are deduced. With a use of meso-mechanical model based on the mixture rule, the yarn segments off-axis elastic matrixes in the RVE and matrixs one are summed with weight; Equivalent elastic matrix of 3D braided composites was deduced. Equivalent engineering elastic constants are achieved in the end. The model can be applied in 2D braided composites mechanical analysis if its geometry is satisfied to the symmetries corresponding to plain point group.

Carbon Nanotube Yarns

Carbon nanotube yarns are embedded in three-dimensional (3D) braided composites with five-axis yarns, which are used as strain sensors to monitor the damage of 3D braided composites. In the cyclic mechanical loading experiment, the strain-sensing characteristics of 3D braided composites were studied by in situ measuring the resistance change of the embedded carbon nanotube yarn. The 3D five-directional braided composite prefabricated part based on carbon nanotube yarns was developed, and the progressive damage accumulation experiments were carried out on carbon nanotube yarns and specimens embedded in carbon nanotube yarns. The research results show that there is a good correlation between the change of relative resistance of the carbon nanotube yarn and the strain of the composite specimen during cyclic loading and unloading. When the tensile degree of the specimen increases beyond a certain range, the carbon nanotube yarn sensor embedded in the specimen shows resistance hysteresis and produces residual resistance. Therefore, the fiber can better monitor the progressive damage accumulation of 3D five-direction braided composites.
