Abstract: An apparatus 1 for continuously forming an FRP square pipe comprises a long core 10 for laminating prepreg sheets, and to this core 10 are fed prepreg sheets from prepreg laminating devices 20, 30, 40 and 50 with a release film interposed between the core, so as to be laminated into square pipe form. The core 10 has an outer diameter size smaller than the inner diameter size of the square pipe to be formed. The outer circumference of the square pipe is wrapped with a tape-like film fed from a tape-like release film wrapping device 200 in spiral fashion, and the work is heated and pressed in a hot press 100. The work is then subjected to additional heating in a postcure furnace 110 to form the FRP square pipe. The square pipe is intermittently pulled by a puller 130 disposed downstream of a clamp 120. The pipe is then cut to predetermined lengths by a cutter not shown to be completed as a product.

Abstract: Disclosed herein is a method by which a material may be placed onto a moving web in a transverse orientation. At least two assemblies, which carry either a first and a second web or a single web, periodically overlap each other in an alternating fashion such that a material may be placed upon their respective carried webs in a transverse manner. The first and second assemblies translate in a direction of web movement in order to modify the velocity of the web carried upon the assembly. Thus, with the velocities of the assemblies capable of being varied, the material may be placed in a transverse manner upon the moving web along with various other orientations.

Abstract: The present invention relates to a method of bonding together two pieces of composite material (10, 26) by applying a layer of glass fibre (20, 28) to a surface of each piece of composite material 10, 26, and bonding the pieces together by means of adhesive (30) between the layers of glass fibre (10, 26). The inclusion of the glass fibre layers (20, 28) advantageously promotes failure of the bond adjacent the glass fibre-adhesive interface rather than at the glass fibre-composite material interface, with the result that damage to the composite material (10, 26) is minimised, and subsequent repair is made easier.
