Abstract
Experiments were carried out to determine the effect of fibre strength on the compressive strength of aligned fibre reinforced composites. The steel reinforcing rods used in this work were hardened to different degrees to control their strength. The compressive strength of composites made with these rods was governed by the Rule of Mixtures, and was a linear function of both volume fraction and fibre strength. The failure strain of the composites was less than one sixth of the matrix yield strain, and failure appears to have been initiated by plastic collapse of the fibres while being fully supported by the matrix.
