Abstract

GONCALVES, Adriano; ALMEIDA, Sérgio F. M.  and  LEVY NETO, Flaminio. Mechanical behavior of carbon/epoxy cylinders under axial compressive loads. Polímeros [online]. 2001, vol.11, n.2, pp.94-101. ISSN 0104-1428.  http://dx.doi.org/10.1590/S0104-14282001000200012.

The requirements of low weight and dimensional stability, combined with high strength and stiffness, for aerospace structures has prompted an increasing use of fiber reinforced materials in manufacturing such structures. In particular, carbon/epoxy cylinders have been widely used in aerospace applications. In this work, an experimental program was developed to determine failure loads, modulus of elasticity and failure modes of 47 carbon/epoxy cylinders shells under compressive loads. The specimens tested had several different length/diameter (from 2.50 to 11.25) ratios and laminate lay-up. These results were compared to the analytical results from finite element code and the most important factors influencing the mechanical behavior of this type of structure were analyzed.

Keywords : Composite materials; compression; carbon fiber; epoxy; cylinder.
