摘　　要：For the better use of composites and a deeper insight into the fracture propa- gation and stress transfer of the interface between fiber and matrix, a theoretical solution of closed form is presented with the assumed bilinear local bond-slip law and a parabolic shear stress distribution along the thickness of the matrix. The load-displacement re- lationship and interfacial shear stress are obtained for four loading stages. Finally, the effects of Young＇s modulus of fiber （matrix） and bond length on the performance of the interface are illustrated.For the better use of composites and a deeper insight into the fracture propa- gation and stress transfer of the interface between fiber and matrix, a theoretical solution of closed form is presented with the assumed bilinear local bond-slip law and a parabolic shear stress distribution along the thickness of the matrix.
