ABSTRACT:
Polyurethane foam-fiber composite structures comprising a flexible polyurethane foam uniformly mixed with a fibrous material and bonded with a liquid flexible resinous binding agent to provide a cured foam structure; the relative amounts of materials in the foam structure being such that for each 100 parts by weight of polyurethane foam particles about 10 to 500 parts of fibrous material and about 10 to 250 parts of binding agent is employed, the fibrous material having a fiber length of from 1/8" to 4" and preferably 1/4" to 3/4", a density of at least 0.75, and a diameter of less than 500 microns. The foam structures have an excellent sag factor with good resiliency for a select density.
