Abstract
A sizing composition including water, a film former, a silane coupling agent, and a weakly-coordinating anion salt is provided. The sizing composition may be applied to fibers used to reinforce polymer compositions. Fiber reinforced composite materials that include reinforcing fibers sized with the sizing composition exhibit improved physical properties, particularly after the fiber reinforced composite material has experience prolonged exposure to heat and water.
