Abstract
The tensile mechanical properties of two polyester / glass crossply laminates cured under different conditions have been investigated. Large thermal strains are generated which severely reduce the strain at which the cracking of the plies is initiated. The two chemically similar resins produced laminates which behaved differently.
The rapid stress corrosion failure of the outer 0° plies of a crossply laminate is shown to be associated with transverse cracks in the 90° ply.
