In this study, we extend our development of the classical lamination theory of laminated composite with
the presence of biaxial fabric prestressed. The aim of this paper is to describe the development of the fibre
prestressed composite and its effect on the composite’s internal stresses when subjected to tensile or flexural
loading. The biaxial fabric prestress of the plain-weave composite could efficiently reduce the overall tensile stress
within the composite lamina due to inducing compressive residual stress imparted from releasing the fibre
pretension load. Thereby, the fibre prestressed composite could withstand more external tensile or flexural stress
than non-prestressed counterparts did.
