LECHO DE DECELERACION PARA VEHICULOS DE ESPUMA DE RESINA AMINOPLASTICA CURADA, NO ELASTICA Y UN METODO PARA LA FORMACION DEL MISMO

摘要

A vehicle deceleration bed comprises two portions of a cured non-resilient aminoplast resin foam material, the density and/or the compressive strength of the foam in one portion being different from that of the other portion. Preferably the portions are arranged in layers and in the case of an aircraft deceleration bed, the lowermost layer is the strongest, each such successive layer being of progressively lower strength.
