Resumo:
This work studies the shear resistance of the composite reinforced with glass/epoxy
fibers of 8 layers. The composite materials are recognized by their excellent combination of
high structural stiffness and low weight. Their inherent anisotropy allows the designer to
tailor the material in order to achieve the desired performance requirements. Thus, it is very
important to develop tools in order to allow the designer to obtain optimized designs
considering the structural requirements, functional characteristics and restrictions imposed by
the manufacturing process. Within these requirements, this work considers the components
manufactured from polymer reinforced materials (epoxy and glass fiber). To this finality, the
beams presented incision in V and the results, the influence of the fibers orientation as well as
the stacking sequences was investigated. Finally, it was proposed a design cycle which
integrates experimental and theoretical procedures in order to get optimized designs in a faster
and reliable way. The samples assayed in elastic regimen conditions and rupture, had
presented tension and module values of high shear for samples with fibre orientation with
angle 45o
and the samples with 0o
e 90o
had presented low values, due to the degreeof
anysotropy or the material.
