Abstract
Treatment in a plasma of a composite reinforcing agent improves the bonding of the agent to the cement portion of the composite. This method facilitates the use of inexpensive readily available light, high tensile strength fibers as reinforcing agents. The reinforcing agents are activated by providing on the surface thereof charged atoms compatible with the cementitious portion of a composite desired to be strengthened.
