Abstract
The present invention provides a sized glass fiber strand adapted to reinforce a polymeric matrix material. The sizing composition includes a polyamide which is the reaction product of a polycarboxylic acid and a polyoxyalkylene amine; an acrylic polymer which is essentially free of epoxy functionality; a coupling agent and a fiber lubricant which is different from the polyamide, the sizing composition being essentially free of a urethane-containing polymer. Composites reinforced with the sized glass fiber strand and a method of reinforcing a composite are also provided.
