Abstract
Methods for inhibiting abrasive wear of a fiber strand comprising at least one glass fiber by sliding contact with surface asperities of a solid object, comprising (a) applying a composition to at least a portion of a surface of at least one glass fiber of a glass fiber strand; (b) at least partially drying the composition to form a sized glass fiber strand having a residue of the composition upon at least a portion of the surface of the at least one class fiber; and (c) sliding at least a portion of the glass fiber strand to contact surface asperities of a solid object, the surface asperities having a hardness value which is greater than a hardness value of the at least one glass fiber, such that abrasive wear of the at least one glass fiber of the glass fiber strand by contact with the surface asperities of the solid object is inhibited by the inorganic solid lubricant particles.
