Abstract

1296740 Laminates DEFENCE SECRETARY OF STATE FOR 28 Oct 1971 [5 Nov 1970] 52404/70 Heading B5N [Also in Division D1] An array of longitudinally aligned carbon, boron or glass fibres 11 is drawn from drum 10 between sheets of silicon release paper drawn from drums 12, 13, one or both paper sheets being coated with epoxy resin on the side facing the fibres, the sandwich is then passed under tension around rollers 14 and 17, at least one of which is heated, so that the resin is transferred to the fibres, and at least one carrier lamina is removed from the impregnated fibre sheet. Preferably, the bonded fabric is taken up by reel 18 whilst the two release papers are taken up by reels 19, 20. Clutches 15, 16 on drums 12, 13 ensure sufficient tension in the paper to force the sandwich against the rollers 14, 17. The nip between rollers 14, 17 is wide, so that resin is not squeezed from the sheet.
