Theory and calculation of stress transfer between fiber and matrix
- 184 Downloads
For the better use of composites and a deeper insight into the fracture propagation 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 relationship 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.
