Filament wound structure and method
Impact resistant blade Carlson, R.G. and Harrison, R.W. (General Electric Company) US Pat 4 000 956 (4 January I9 77) A blade for use in a fluid flow machine having a tip portion and a root portion fabricated from a numbe of bonded filament laminates. The laminates consist of a number of continuous collimated filaments embedded in a first matrix at the blade root and a second matrix at the blade tip; both matrices are bonded together at a common interface, the second matrix is made of two materials sandwiching the filaments, and has a greater impact strength than the first matrix.

US Pat 4 002 714 (11 January 19 77) A method of manufacturing a tapered bent pipe of glass fibre-reinforced synthetic resin material with a base plate integrally attached to the larger end.
Plastic socket made of fibre-reinforced thermosetting resin material Schuldink, G. (Industriele Onderneming Wavin N.V.) US Pat 4 003 591(18 January 1977)
Process for producing carbon fibres having excellent physical properties Matsumura, Y., Kishmoto, S. and Okazaki, S. (Japan Exlan Company Limited) US Pat 4 001 382 (4 January 1977) A process for producing carbon fibres having a high strength and a high modulus of elasticity by heating acrylonitrile copolymer fibres (made from an acrylonitrile copolymer containing at least 80% acrylonitrile). The acrylonitrile copolymer contains 0.3 to 6% of an unsaturated carboxylic acid and its alkali metal or ammonium salt; and the content of the carboxylic groups in the salt form in the fibre is 0.1 to 15% based on the total amount of carboxyl groups and their salts in the fibre.
Composition for reinforced and filled high density rigid polyurethane foam products and method of making same Deaver, D.T. (Tecnik International Corporation) US Pat 4 005 035 (25 January 19 77) A process for manufacturing in a mould, a rigid polyurethane foam product containing silica sand and chopped glass fibres.
Method of forming and sizing glass fibers Graham, R.R. (PPG Industries Inc) US Pat 4 002 445 (11 January 1977) A method of forming glass fibres by drawing glass filaments from molten cones of glass at high speed; applying to the filaments, during formation, an aqueous size of a starch, a lubricant, a textile softener, and a nonionic wetting agent. The size contains 150 to 100 percent by weight of the nonionic wetting agents (baaed on the weight of the lubricant). The strand is wound on a rapidly rotating forming tube.
High Modulus, high strength carbon fibres produced from mesophase pitch Singer, L.S. (Union Carbide Corporation) US Pat 4 005 183 (25 January 1977) A fibre is described which has a structure possessing the threedimensional order characteristic of polycrystalline graphite, has a diameter no greater than 30 pm; a tensile strength greater than 1.38 GN/m’; and a Young’s modulus of eleasticity greater than 344 GN/m2.
