【 摘 要 】

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.
