Method of forming automotive headliners from composite foamed resin blanks (Miller, F.O., Saginaw, MI, USA) US Pat 4 327 049 (27 April 1982) The method produces an article in which a first layer of resilient or relatively soft, cellular foamed thermoplastic is laminated to and sandwiched between a second layer of relatively stiff, cellular, foamed thermoplastic and a third layer of fabric.
Method of manufacturing goods of laminates and goods so manufactured (Norzi, V., Rho (Milan), Italy) US Pat 4 327 142 (27 April 1982) In a method for manufacturing a laminate panel by injecting and expanding a plastic material onto a face of a base layer in a mould,
COMPOSITES . JULY 1984
the bond between the base layer and the expanded layer is improved by wetting the face of the base layer with a liquid volatile solvent, applying a layer of pre-expanded plastic pellets onto the wetted surface thus partially dissolving the pellets and causing them to stick to the base layer, evaporating the solvent through the interstices between the pellets and then carrying out the injecting and expanding of the plastic material.
Process for producing sheet molding compound Mitani, T., Ogasawara, Y. and Hiraishi, S. (Dainippon Inc & Chemicals Inc, Tokyo, Japan) US Pat 4 327 145 (27April 1982) This process produces easily handleable sheet moulding c o m p o u n d containing 40-75% by weight glass fibres in polyester resin.
Method of preparing concrete column for attachment to beam (Destree, A.L., Everett, WA, USA) US Pat 4 327 703 (4 May 1982) A method for preparing a concrete column containing elongated reinforcing elements for engaging with a superjacent cast-in-place concrete m e m b e r involves removing the concrete from the column to reveal the reinforcing elements and casting the beam around these.
Process for the treatment of aromatic polyamide fibers, which are suitable for use in construction materials and rubbers, as well as so treated fibers and shaped articles reinforced with these fibers Kock, TJ.J.M. and Smits, J.J.G. (Nederlandse Organisatie voor Tiegeoast-Natyyrwetebscgaooekehj Ibderziej ten behoeve van Nijverheld Handel en Verkeev, The Hague, The Netherlands) US Pat 4 328 324 (4 May 1982) An aromatic polyamide fibre is drawn through at least one capillary entrance and outlet through a tube in which the pressure is reduced and which contains a plasma. The fbres can be used to reinforce a plastic or rubber matrix material.
In-the-mold coating apparatus and method Arnason, S.I. and Kleese, EJ. (The General Tire & Rubber Company, Akron, OH, USA) US Pat 4 329 134 (11 May 1982) In an apparatus for moulding a glass fibrereinforced thermosetting plastic, an injector for injecting a coating resin onto the composite when the dies part is positioned so that the stream flows parallel from the injector onto the surface of the part.
Method for constructing fiberglass articles Green, A., Rogers, C.W. and Upton, C.D. (Composite Technology Inc, Fort Worth, TX, USA) US Pat 4 329 194 (11 May 1982) A glass fibre-reinforced article is formed by drawing a web of glass fibres through a bath of structural resin, drawing a web of gelcoat resin containing a UV stabilizer and pigment, pressing the two webs together, then placing the composite on a mould to shape it, and curing.
Method of making a three-dimensional laminate Rawlinson, G.R. (Monsanto Company, St Louis, MO, USA) US Pat 4 329 196 (11 May 1982) The method involves continously feeding a normally solid adhesive layer between a heat-
sensitive, unfoamed three-dimensional layer and a near molten thermoplastic substrate sheet to form a three-layer laminate. The heat loss from the exposed surface of the substrate is inhibited to balance the heat flow from opposing surfaces to produce a laminate substantially free of thermal distortion.
Prepreg material having increased surface tack Goodrich, ILB. and Moulton, RJ. (Hexcel Corporation, San Francisco, CA, USA) US Pat4 329 387 (11 May 1982) The prepreg is formed from a fabric of highmodulus graphite fibres and uncured resin which impregnates the fabric and is entirely absorbed by it, the a m o u n t of resin being less than that desired in the finished article. Discrete quantities of uncured resin are then added to at least one surface of the impregnated fabric, rendering the surface tacky. The quantity of resin added is such that it is the difference between the a m o u n t of resin required in the finished article and that trapped in the fabric.
Method of forming a urethane prepolymer and its use in consolidating aggregate material (Dedolph, R.IL Naperville, IL, USA) US Pat 4 329 436 (11 May 1982) Aggregate material is consolidated to form an integral, resilient, water-permeable mass by adding and reacting a polyether or polyester and an isocyanate c o m p o u n d to form a cellular polymer which binds the material.
Method of making strips of metallic glasses containing embedded particulate matter Narasimhan, M. (Allied Corporation, Morris Township, NJ, USA) US Pat 4 330 027 (18 May 1982) The title material is formed by forcing a stream of molten metal containing the dispersed particles to come into contact with the surface of a moving chill body. The metal then solidifies on the chill body to form a continuous strip containing embedded particles.
Reinforced foamed resin structural material and process for manufacturing the same Iwata, A. and Fukushima, S. (Sekisui Kagaku Kogyo Kabushiki Kaish a, Osaka, Japan) US Pat 4 330 494 (18 May 1982) A process for preparing a foamed structural material is described in which a honeycomb is placed between two or more layers of fibre material and a foamable thermosetting resin is applied. The foam fills the voids of the honeycomb and permeates and covers the fibre materials.
Method of fabricating a reinforced composite structure Lackman, L.M. and Hill, J.A. (Rockwell International Corporation, El Segundo, CA, USA) US Pat 4 331 495 (25 May 1982) The method comprises staging two panels of adhesively bonded fibre-reinforced plies, stiching the panels together with uncured, flexible composite thread, and co-curing the panels and thread.
