  • Vibration-damping composite sheet steel
    Patent number: 5093204
    Abstract: A vibration-damping composite sheet steel made by sandwiching a viscoelastic material between two steel sheets. A rust proofing coating which generates no gaseous matter is formed on one surface of each of the steel sheets which is contacted with the viscoelastic material. The coating is a phosphate coating having no water of crystallization with a coating weight per unit area of 0.5 g/m.sup.2 or over, or a galvanized zinc coating including no zinc oxide.

  • Continuous process for producing reinforced resin laminates
    Patent number: 4994133
    Abstract: A continuous process for producing reinforced resin laminates comprising the steps of impregnating a fibrous substrate with a liquid resin which is free of volatile solvent and is capable of curing without generating liquid and gaseous byproducts, laminating a plurality of the resin-impregnated substrates into a unitary member, sandwiching the laminate between a pair of covering sheets, and curing the laminate between said pair of covering sheets without applying appreciable pressure. The improvement comprises adjusting the final resin content in said resin impregnated substrate at 10 to 90% by weight based on the total weight of said impregnated substrate.
