ABSTRACT:
A composite structural member is constructed to take up dynamic loads. A force transmitting element is glued to a force applying element and to a force take-up element to form the composite member. The force transmitting element is a molded blank of cellular polyurethane having an open cell structure throughout. The open cells also extend along the surfaces glued to the force applying element and to the force take-up element. The glue or adhesive used is a moisture curing polyurethane prepolymer capable of penetrating into said open cell structure, thereby greatly increasing the adhesive bond.
