Abstract

The paper presents the elasticity evaluation of some advanced symmetric composite laminates based on epoxy resin reinforced alternatively with HM carbon, HS carbon and kevlar49 fibres. The laminates taken into account into this evaluation have following plies sequences: [0/30/-30/60](S), [0/45/90](2S) [90/45(2)/0](S) and are subjected to off-axis loading systems. The elastic constants as well as the tensile-shear interaction have been determined. In order to obtain equal stiffness in all loading systems, a composite laminate have to present balanced angle plies.
