Method of welding together graphite fiber reinforced thermoplastic laminates
A method of forming a composite mould for the production of composite parts is described. Epoxy-resin impregnated fabric is layed-up on the part, formed into a cathode, bagged, cured under applied pressure and temperature. Method of making an acoustic panel with a triaxial open-weave face sheet
Stephens, G. E. (Rohr Industries, Inc., Chula Vista, CA, USA) US Pat 4 671 841 (9 June 1987)
A fully cured, epoxy resin impregnated fabric sheet comprising carbon fibre tows woven in a triaxial pattern with 25-33% open area is described, used in making acoustic panels. Process for the manufacture of carbon fibers and feedstock therefor

Burke, J. H. (The Boeing Company, Seattle, WA, USA) US Pat 4 673 450 (16 June 1987) Graphite-fibre reinforced polyetheretherketone laminates are welded together by softening the polyetheretherketone in surface contact by applying voltage and amperage across opposed electrodes sited either side of the laminates in surface contact.
mole % alpha hydrogens (based on moles present in pitch), 15-40 weight % xylene insolubles, 0-5.0 weight % quinoline insolubles, 0.1-4 weight % sulphur, 65-90 weight % coking value and 0-5 weight % mesophase content, having a softening point of >250°C and a reduced stabilization time, especially adapted for use in the manufacture of carbon fibres.
Method and apparatus for continuous shaping of carbon-fiber-reinforced plastic tubes
Method for producing fiber reinforced hollow microspheres
Cochran Jr., J. K. (Materials Technology Corporation) US Pat 4 671 994 (9 June 1987) Fibre-reinforced hollow microspheres (diameter 500-600 ~tm, wall thickness 5.0-400 tam), made of film forming materials and possessing filaments of the same material connecting the microspheres together, are free of gases and gas-producing materials with walls relatively free of holes, thinned areas and bubbles.

Watanabe, T., Sugano, T., Yamamoto, Y. and Murayama, K. (Agency of Industrial Science and Technology, Tokyo, Japan) US Pat 4 673 541 (16 June 1987)
Carbon fibre prepreg in tape form, impregnated with thermosetting resin, is laminated on a mandrel, preheated and pulled through a hot die comprising resin squeezing, gelling and curing zones. The carbon-fibrereinforced plastic tubes formed (wall thickness ~<0.5 ram) are pulled from the hot die together with the mandrel, by two alternate operations.
