A lightweight energy-absorbing structure is comprised of a laminate including a plurality of fabrics, pre-impregnated with a thermosetting resin, abutting against a core of cellular foam treated with a charge of filled bonding material. The resulting mixed materials are compressed between two die members while heat is applied to the dies thereby single curing the thermosetting resin and bonding material. Individual sheets of fabric may have a predetermined orientation to increase impact resistance. In a preferred embodiment polyimide open-cell foam may be employed.
