“…Figure 3 shows the longitudinal (α 3 ) and transverse (α 1 = α 2 ) CTE versus fiber volume fraction for a unidirectional glass/epoxy composite. Included in the figures are also predictions obtained by other approximate closed-form solutions [Van Fo Fy 1965;Rogers et al 1977;Chamis 1984], FEM [Haktan Karadeniz and Kumlutas 2007] method and experimental measurements [Sideridis 1994]. It can be seen in the figures that predictions of the MLPG method are in the close agreement with the FEM and experiment for both longitudinal and transverse CTE.…”

“…However, there are some discrepancies between the results of various approximate closed-form solutions in the transverse CTE of the glass/epoxy composite, mainly due to their various simplifying assumptions. Table 2 shows the CTE of SiC/Ti composite system predicted by MLPG, FE and approximate closedform solutions [Van Fo Fy 1965;Rogers et al 1977;Chamis 1984]. Again, very good agreement is seen between the results of MLPG and FE model while some differences exist in the predictions of approximate methods (loc.…”

“…The influence of residual stresses on the yielding behavior of composite materials was studied in [Dvorak et al 1973;Zahl and McMeeking 1991;Aghdam et al 2000;Aghdam and Khojeh 2003], while [Gentz et al 2004] and [Zhao et al 2007] studied the effects of the residual stresses on the behavior of polymer-matrix composite. In addition, the overall coefficient of thermal expansion of composite materials was studied using micromechanical finite element [Shen 1998;Haktan Karadeniz and Kumlutas 2007], approximate closed-form models [Van Fo Fy 1965;Rogers et al 1977;Chamis 1984], and experimental methods [Sideridis 1994]. …”

A generalized plane strain micromechanical model is developed to predict the behavior of a unidirectional fiber-reinforced composite subjected to combined thermal and mechanical loads. An appropriate meshless local Petrov-Galerkin formulation is presented for the solution of the governing partial differential equations of the problem. To reduce computation time, a unit step function is employed as test function. A direct method is presented for enforcement of the continuity of displacement and traction at the fiber-matrix interface to model the fully bonded interface. Results of this study revealed that the model provides highly accurate predictions with relatively small number of nodes. Numerical results for glass/epoxy and SiC/Ti composites subjected to thermomechanical loading show that predictions for both local and global responses of the composites are in good agreement with results of theoretical, experimental and finite element methods.

“…Rogers et al [6] studied the thermal expansion coefficient variation with temperature in high modulus and high strength carbon fiber unidirectional laminates. They observed that the thermal expansion coefficient in the fiber direction tends to increase as temperature decreases whereas the opposite occurs in the laminate transverse direction.…”

This paper summarizes the results of the tests to determine the effect of the low temperature on the mechanical behavior of carbon fiber reinforced epoxy laminates. Tensile and bending static tests were carried out on two laminate lay ups (quasi isotropic and cross ply laminates), determining properties such as the mechanical strength, stiffness and strain to failure. The results show the changes in the mechanical behavior of this material at different test temperatures (20, 60 and 150 8C).

“…Carbon fibres are thermally anisotropic, as they possess a negative CTE in the longitudinal direction and a positive CTE in the transverse direction [42][43][44]. However, Wong reported positive CTE values at the two principal directions [32].…”
