Properties of spray-applied rigid polyurethane foam filled with chopped glass fibers 4 mm long are investigated. Effects of filler content (3 – 18 wt. %) on modulus of elasticity and strength of filled foam at tension and compression are estimated. An increase in modulus of elasticity in the transverse direction up to 20% with increasing content of chopped glass fibers is observed. The strength of filled polyurethane foams decreased or was unchanged at loading of chopped glass fibers. Cellular structure, as well as failure mode of filled foams at tension is analysed.
