  • Patent number: 5788760
    Abstract: The present invention relates to processes for enhancing the bond strength of a cement matrix including reinforcement fibers and for modifying the surface characteristics of reinforcement fibers useful in cementitious materials. The processes further relate to controlling the interface properties and, more particularly, the bond strength (.tau.) and interface toughness (T.sub.i), between synthetic fibers and a cementitious material forming a matrix. By plasma treating synthetic fibers with an excitable gas capable of displacing hydrogen atoms occurring along said reinforcement fibers, the bond strength and interface toughness of the composite is dramatically increased over composites employing non-plasma treated fibers.
