Method of manufacturing a fiber reinforced composite material Heissler, H., Hitsch, E. and Scheer, W. (Maschinenfabrik Augsburg-Nurnberg Aktiengesellschaft) US Pat 4 050 997 (27 September 1977) A process for producing reinforcing carbon fibres is described. The fibres comprise a carbon fibre substrate with a light metal or metalloid coating. Composite of rubber bonded to glass fibers van Gils, G.E. and Kalafus, E.F. (The General Tire & Rubber Company) US Pat 4 051 281 (27 September 1977) A glass fibre reinforcing element is bonded to a rubber compound using a composition comprising an aqueous alkaline suspension of a rubbery vinyl pyridine copolymer, timethylol phenol, a rubbery vinyl pyridine copolymer trimethylol phenol, a thermoplastic and non heat hardenable resorcinol NH4 OH or NaOH and water.
Carbon fibre is made from a multifilament tow of organic precursor fibre, heated in an oxygen containing atmosphere, carbonised and, optionally, graphitised. The fibre is twisted between the oxygen treatment and carbonisation to keep the fibres within the tow. Method and apparatus for making fiber reinforced tape Chen, H.T. US Pat 4 052 239 (4 October 1977) Composite coalescing filter tube Berger, L.J., Jr., and Guegierre, D.D.

Reinforced flame retardant polyester composition having non-drip characteristics Berardinelli, F.M. and Edelman, R. (Celanese Corporation) US Pat 4 052 360 (4 October 1977) A process for preparing a reinforced flame retardant copolyester moulding resin composition is described which has a non-drip characteristic.
Method ff producing reinforced sheet material Wilson, A., Marr, W.D. and Guild, G.A. US Pat 4 051 288 (27September 1977) The reinforced sheet comprises a layer of foam reinforced with a stitched system Method of reinforcing the handle of of non-extensible yarn parallel to the hockey sticks foam's surface. Goupil, M. and Ruel, M. US Pat 4 052 499 (4 October 1977) The handle (wood or foamed plastics) Fiberous batt and method for is reinforced using a roving of reinproducing such forcing fibres, impregnated with Sumner Buck, G., Jr., Weyker, R.G. uncured thermosetting resin. These and Ward, A.G. (Fiberlok Inc) US Pat are processed so that when cured 4 051 294 (27September 1977) they are arranged longitudinally along The fibrous batt consists of thin webs the handle. of cotton and polyester fibres bonded together with vinyl chloride and vinylidene chloride copolymers. The batt is heated to a temperature above the sticking point of the copolymer but below the melting point of the polyester. Production of carbon fibre Blakelock, H.D.

Process for reinforcing aluminium alloy Riewald, P.G., Krueger, W.H. and Dhingra, A.K. (E.I. Du Pont de Nemours and Company) US Pat 4 053 011 (11 October 1977) Polycrystalline alumina fibres are placed in a mould. A composite reinforced with 10-80% of fibres and having a porosity of less than 10% is
then formed by infiltrating the fibres in the mould into a molten aluminium alloy (containing 1-8% Li) for long enough for a sheath to form around the fibres. Reinforced filament-wound cut-port pressure vessel and method of making same Minke, C.M. (The United States of America - Secretary of the Navy) US Pat 4 053 081 (11 October 1977) The vessel is wound at a constant helical winding angle that can be predetermined and has polar end openings one of which is larger than the other. Fiber reinforced plastic handrail system Clemens, D.L. and Edmiston, S.A. US Pat 4 053 140(11 October 1977) The method of construction of the handrail is described. Methods of making fiber reinforced plastic pipe Carter, J.W.

(Bayer Aktiengesellschaft) US Pat 4 053 537 (11 October 1977) The elastic composite comprises a rubber coating and/or elastomeric plastic granules and a polyisocynate binder. Process for manufacturing laminated structural foam articles Fay, C.C. (Standard Oil Company) US Pat 4 053 545 (11 October 1977) The laminated article comprises a thermoplastics sheet bonded to and supported by a thermoplastics foam. Stiffened structural laminate and method of molding laminate with stiffener beads Smith, B.W. (Lockheed Aircraft Corporation) US Pat 4 0.53 667 (11 October 1977) The rib stiffened laminate is formed by sandwiching a strip of honeycomb core between two layers of a curable
