| Abstract | A study of stress transfer near the ends of the whisker in a simulated whisker reinforced composite material was conducted by using photoelastic techniques. The composite material studied was αAl₂O₃ whiskers in an aluminum matrix. The photoelastic models used consisted of a scaled-up macroscopic stiffener embedded in a three-dimensional epoxy matrix. The factors controlled during testing were the stiffener geometry, the ratio of modulus of elasticity of the stiffener to that of the matrix, and matrix thickness with respect to the range of influence of the stiffener. The models were loaded in tension and compression to obtain photoelastic stress patterns. Then these stress patterns were duplicated by locking-in techniques. The models were sliced and analyzed. The normal and shear stress distributions along critical directions and the stress transfer length were determined and compared with the theoretical and experimental results of other investigators. |
