Reinforced thermoplastics

Apparatus for manufacturing curved bodies of fibre reinforced plastic Hampshire, W3. (Goodyear Tire & Rubber Company) US Pat 3 988 089 (26 October 1976) A stream of fibres is deposited onto a horizontal support to form radii of curvature of the curved body. As the support turns a layer of plastics is deposited over the fibrous layer. A second fibrous layer is then laid circumferentially on the plastics layer, followed by a second plastics layer. Hence a preform is built up of successive layers of fibres and plastics. Assembly for the drawing of glass fibres Coggin, C.H., Jr. (Kaiser Glass Fibre Corporation) US Pat 3 988 135 (26 October 1976) A glass fibre drawing assembly of the type having a non-tip orifice plate.

(Celanese Coatings & Specialities Company) US Pat 3 988 279 (26 October 1976) A cement composition comprising 100 parts of hydraulic cement, 7-75 parts of a curable epoxide resin powder, 20-300 parts of water and 10-500 parts of aggregate. Reinforced thermoplastics Wurmb, R., Kunde, J., Stein, D., Gausepohl, H. and Theysohn, R. (BASF Aktiengesellschaft) US Pat 3 988 284 (26 October 1976) Thermoplastic polycondensates and polyadducts containing 10-60% of conventional reinforcing agents and 0.05-2% of a styrene oligomer. Process for the addition of additives to thermoplastics De Vrieze, C.G. (Stamicarbon B.V.) US Pat 3 988 285 (26 October, 1976) A process for adding to a molten thermoplastics resin, solid additives which are heat-stabilizers, anti-oxidants, UV-stabilizers, internal or external lubricants, antistatic agents, antiblocking agents or corrosion-inhibitors. Moulding compositions of a resin and hydrated cement Clark, J.O., aankins, B.J. and Cottrell, W.D., Jr., (Owens-Coming Fibreglas Corporation) US Pat 3 988 289 (26 October 19 76) An uncured mouldable composition of 10-90% phenolic resin and 90-10% of hydrated cement.

Method for producing moulded bodies from curable binder-bearing glass fibres Gambill, U.T. and Brock, G.C. Jr., (Owens-Coming Fibreglas Corporation) US Pat 3 988 407(26 October 1976) Method of severing a flex~ie reinforced elastomeric conduit supported on a plurality of elongated end-to-end rigid mandrels Holden, H.N., et al (Dayeo Corporation) US Pat 3 988 409 (26 October 1976) Method of making pipe having a liner layer of mixed resins Woodson, C.S. (Youngstown Sheet and Tube Company) US Pat 3 988 412 (26 October 1976) A method of producing reinforced plastics pipe by positioning a reinforcing cylinder of fibrous material in a cylindrical mould; introducing thermosetting resin into the mould and spinning the mould to form the outer shell of a pipe; and then introducing into the pipe shell a mixture of thermosetting and thermoplastic resins. The pipe is rotated to spread the resins evenly. Method for producing carbon fibres Ogawa, T., Wakita, E. and Kobayashi, T. (Asahi Kasei Kogyo Kabushiki Kaisha) US Pat 3 988 426 (26 October 1976) The method comprises subjecting acrylonitrile polymer fibres to preliminary heat treatment in an oxidative atmosphere at between 180 and 300°C and then carbonization heat treatment at between 700 and 2800°C.

F~re coated thermoplastic George, P.D. and Boudreau, R.J.
