Abstract
A formable matrix used as structural material and having an admixture of reinforcing non-metallic meltable fibers. The fibers have enlarged knob-like ends serving as anchors to enhance the bonding action between the fiber and the matrix. The admixture reduces freeze-thaw losses and improves flexural strength of the matrix. Several methods of forming the fiber end knobs are disclosed.
