Uma introdução a placas laminadas constituídas de materiais compostos em fibras longas.

Abstract

An introductory and brief text about the long fiber composite materials in the laminated plates field is presented. General considerations are made about composite materials related to its constitutive components, as well as the main materials used in its building. The anisotropic mechanical behavior of long fiber composite materials is characterized,  and the linear elasticity expression are developed to orthotropy, transversal isotropy and full isotropy. Thermoelastic properties from these materiais are also presented and a simple method to its determination, called Rute of Mixtures, is shown. The laminated composite materiais nomenclature is described and the bending laminated theory is also shown. At the end, long fiber laminated composite strength is analyzed and the Tsai-Hill failure criterion and the Lee delamination criterion are presented. Conclusions about diversity and wide range of composite materials study, are reached.
