In the current study, the model, previously developed by Wilson, was reviewed and extended to predict the mechanically induced spreading of E-glass fiber bundles. The widths of the as-received E-glass fiber bundles were increased by 200-250% when subjected to a series of reciprocating motions. A 350-450% increase in the widths of the bundles was observed when the tension was released (tension-release mechanism) and the reciprocating motions repeated. The effect of the number of rods, angles and distances between them, and their relative geometry on the extent of fiber spreading was studied. The forces involved in fiber spreading are discussed using micro-mechanics involved in the fiber spreading.
