ABSTRACT:
Reinforcing fibers of plastic having a surface tension of from 40 dyn/cm to about the surface tension of water are disclosed. The fibers can be easily and uniformly disposed in matrices. For organic matrices, a surface tension of 40-50 dyn/cm is effective. For cement matrices, a surface tension about 70-75 dyn/cm is effective. The high surface tensions are obtained by a corona treatment and subsequent application of a hydrophilic avivage. Corona treatment may be performed on the fibers, or on films from which the fibers are made.
