Abstract : The micromechanics of fiber composite columns under compression is investigated theoretically. The model is based on the assumption that the fiber buckles inside the matrix under critical load. In the postbuckling range the fiber is considered as a beam on elastic foundation. The value of the foundation constant is evaluated for the case of a long fiber encased in a cylinder. It is shown that prebuckling separation between fiber and matrix affects the critical buckling load and the postbuckling behaviour of the fiber. Computations based on the proposed model show that in the linear elastic range of common materials the buckling of the fiber does not affect significantly the overall mechanical behaviour of the composite.
