Abstract
The composite term refers to a compound of two or more components, in macroscopic level, which does not have solubility with each other and that combined form a union of the best features of each one. The objective that generated the development of these materials was structural. Hence, the mechanical properties are the parameters that get further of study interest, such as the modulus of elasticity. The study of the thermal influence in this property is very important, which objective is verifying the viability of the material in different projects. This paper evaluated the thermal effects on longitudinal and transverse modulus of elasticity of a carbon-epoxy laminate using the Standard ASTM E1876.Two methods of characterization of laminated were analyzed, macromechanical and micromechanical composites, as well as the glass transition temperature of the material. As found in the literature, it was demonstrated by experimental data that the thermal effects reduce more the transverse stiffness value (41.67%) in relation to the longitudinal stiffness value (14.12%) up to a certain temperature.
