An experimental study of static strength and failure mechanisms of G-10 woven composites laminates was conducted on tubular specimens. Loading conditions included tension, compression, internal pressure, and external pressure to produce any desired combination of axial and hoop stresses or strains. Small IITRI and larger tubular specimens tested in tension in both fill (axial) and warp (hoop) directions failed in a typical tensile failure mode of fiber fracture. Under uniaxial compression loading, IITRI specimens failed by out-of-plane kinking in both fill and warp directions. Tubular specimens failed by out-of-plane kinking in the fill (axial) direction and delamination followed by out-of-plane kinking in the warp (hoop) direction. Both IITRI and tubular specimens have the same failure mode in compression in the fill (axial) direction which results in the same failure strength. Delamination failure for tubular specimens in the warp (hoop) compression causes 50% loss of failure strength compared with IITRI specimens. However, the delamination did not reduce the failure strain. For tubular specimens under biaxial loading, biaxial stress state without an in-plane shear can be adequately described by a maximum stress or maximum strain criterion considering different failure modes.
