Silane Concentration

Mode I interlaminar fracture behaviours were investigated on the laminated composites reinforced with plain glass woven fabrics which were treated with different silane concentrations. The low silane concentration specimen indicated higher fracture toughness, compared to the high silane concentration specimen. This is due to the occurrence of the micro crack in the fibre strands. In the low silane concentration specimen, larger damage zone due to the micro crack was formed ahead of the crack tip.

Fabric Composites

Mechanical properties of woven fabric composites are influenced by fabric geometry and harness. In the present research, woven fabric composites made of ML-506 epoxy resin and E-glass woven fabrics with three different fabric geometries (harnesses of 2, 5, and 8) were studied experimentally. The new concepts of warp and fill-fiber volume fractions were introduced. Based on these new concepts, a micromechanical model for predicting the stiffness and strength of composites made of woven fabrics was developed. An experimental program was conducted to evaluate the present model and the new concepts of warp and fill-fiber volume fractions. The results obtained by the new micromechanical model have been compared with the conducted experimental results as well as the experimental data available in the literature, and very good correlations were obtained.

Memory Cycle

Based on continuum mechanics and finite element method, a lamination model was developed for shape memory polymer composites (SMPCs) reinforced by woven fabrics. SMPCs were modeled as a laminated structure with woven fabric reinforcements embedded in shape memory polymers (SMPs). Thermo-responsive SMPs were defined by a 3D phenomenological model based on the phase transition approach, while woven fabric reinforcements were characterized by an anisotropic hyperelastic model. The proposed model was validated by comparing numerical results of a SMPC in the shape memory cycle of bending deformation with experimental data. Applications of the lamination model were demonstrated on numerical simulations of a tube made of SMPC in three shape memory cycles with different deformation modes. The proposed model is simple and applicable in the simulations of various shape memory cycles related to SMPCs. It also provides a theoretical foundation for the analysis and design optimization of woven fabric reinforced SMPC structures.

Stress Levels

This paper describes a self-developed MATLAB program for achieving complex deformation properties and accurate elastic parameters of woven fabrics. Using this program, the response surface analyses of deformation and elastic parameters were conducted to reveal the variation and evolution in stiffness, Poisson’s ratio, and orthotropy of the laminated woven fabric composite under different loading/unloading stages, cycles, stress levels and ratios, which is a further development of our prior work. Results show that elastic parameters and orthotropic characteristics of the material vary noticeably with the loading/unloading stages, cycles, stress levels, and ratios. As higher values are required to model the remarkable warp–weft interaction and large negative strains, Poisson’s ratios in boundary regions with a maximum of 1.0 (loading) or 1.5 (unloading) are outside the bounds normally expected for these parameters. In addition, the proposed method is feasible to evaluate elastic parameters for any stress state, and thereby provides new insights into underlying deformation mechanisms of woven fabric composites.

Finite element representative unit cell models are established for the study of progressive failure of woven fabrics: plain weave, twill weave, and satin weave. A multi-scale approach ranging from the meso-scale to micro-scale regime is used, providing the failure observation inside the constituents. The constituent stresses of the fiber and matrix in the warp and fill tows of the woven fabric unit cell are calculated using micromechanics. Correlations between meso-scale tow stresses and micro-scale constituent stresses are established by using stress amplification factors. After calculating micro-scale stresses, the micromechanics of failure damage model is employed to determine the progressive damage statuses in each constituent of woven fabric composites. For the matrix of tows, a volume-averaging homogenization method is utilized to eliminate damage localization by smearing local damages over the whole matrix region of the unit cell. Subsequently, the ultimate strength is predicted for woven composites with different tow architectures. The prediction results are compared with the experimental values, and good agreement is observed.

Fiber Misalignment

Unit cell modeling of woven fabric composites at meso-level has been advantageous in finding equivalent mechanical properties of different weave architectures without performing physical experiments on each new fabric. The obtained properties, in turn, can be used in the macro-level modeling and simulation of large composite structures. Models used for this purpose, however, often consider a perfect description of unit cells, while in practice fabrics are not always fabricated under ideal conditions and flaws like fiber misalignment, material and/or geometrical defects are present. A benchmark work covering effects of this kind on the mesoscopic behavior of woven fabrics is underway. The aim of this paper is to present a statistical way to approach the problem by studying the main effects of such uncertainty/noise factors along with their levels of significance. Namely, a one-factor-at-a-time screening method is selected to identify the effect of (1) fiber misalignment, (2) fiber modulus variation, (3) geometrical flaws in yarn section, (4) unpredictable friction between weft and warp yarns. Computer experiments are done using FE modeling of a plain weave unit cell under the uniaxial, equibiaxial, and trellising (shear) modes. A parameter sensitivity analysis is conducted to identify the most significant factors and the extent to which each can independently contribute to the variation of load-displacement curves (i.e., testing data non-repeatabilities).
