    摘要: LIGHTWEIGHT STRUCTURES OF HIGH SPECIFIC MODULUS AND SPECIFIC STRENGTH (MODULUS OF ELASTICITY AND ULTIMATE STRENGTH, RESPECTIVELY, DIVIDED BY DENSITY) CAN BE ACHIEVED BY STRUCTURAL LAMINATES COMPRISING RIGID MATERIALS CHARACTERIZED BY BRITTLENESS AND HIGH STIFFNESS FORMED AS FILMS AND LAID UP IN LAMINATES. THE ADJACENT FILMS OF THE LAMINATES ARE SECURED TO EACH OTHER BY ADHESIVES OR HOT PRESSED SELF BONDING. THE LIMINATES OFFER A SIGNIFICANT ADVANTAGE OVER THE PRIOR ART FILAMENT AND FIBER REINFORCED COMPOSITE SYSTEMS IN THAT THE LAMINATES OFFER THEIR STRENGTH AND RIGIDLY IN ALL DIRECTIONS IN THE PLANE OF THE LAMINATE.
