Definitions

  • This invention relates to fibre-reinforced synthetic resin composite articles and in particular to a method of manufacturing the same.
  • a process for the manufacture of a fibre-reinforced synthetic resin article comprises the steps of forming an aqueous suspension of fibres by intimate blending of water-dispersible reinforcing fibres and web forming fibres in the absence of a binder material, and thereafter producing a shaped fibrous preform from said suspension by a vacuum forming operation, followed by drying the preform.
  • the suspension may contain a finely powdered thermosettable resin material, for example, a phenolic resin, so that the dried preform is ready for compression moulding directly into a shaped article.
  • a finely powdered thermosettable resin material for example, a phenolic resin
  • the dried preform can be impregnated with a liquid resin composition immediately prior to moulding it under heat and pressure into a shaped article.
  • Preferred reinforcing fibres include carbon fibres, staple aramid fibres and glass fibres. Other fibres may also be used, for example nickel coated carbon fibres to confer a degree of electrical conductivity.
  • the web-forming fibre component may be cellulose, but for higher temperature applications, aramid fibre pulp is preferred.
  • the thermosettable resin powder is incorporated during intimate blending of the fibre components to make the suspension, it should be selected so as to be inactive at the temperature subsequently used to dry the preform. It has been found that the web-forming fibre content of the suspension should not be less than 5%, referred to the total weight of fibres present.
  • the web-forming fibres may comprise as much as 50% of the total fibre content and by varying the proportions of the fibre components it is possible to vary the properties of the end product.
  • the web-forming content is relatively large, it may be necessary to incorporate the resin component into the suspension as a powder, in order to ensure that the resin in thoroughly and uniformly dispersed. This is because relatively high proportions of web-forming fibres tend to result in a dense structure which is not easily impregnated with liquid resin.
  • the suspension may also contain particulate fillers selected to modify the thermal, mechanical, friction and/or electrical properties of the finished shaped article.
  • suitable fillers include metal flakes, graphite, micas, barytes, glass microspheres and lubricants such as molybdenum disulphide, where necessary finely powdered to ensure dispersion.
  • a laminate was made by superposing phenolic resin impregnated woven asbestos fibre fabric sheets.
  • the resultant assembly was press-cured in conventional manner to produce a composite sheet, from which were cut both samples for physical testing purposes and a number of samples for use as rotor vanes in a vacuum pump.
  • Example 2 represents the wear rate of the rotor blades made from a non- asbestos composite comprising layers of a woven textile fabric containing 7% by weight aramid fibres and the rest being glass fibre core strands overlaid with staple cellulose fibres (viscose) using the DREF spinning process. These fabric layers were laminated using phenolic resin to form a composite slab which was cut/machined into rotor blades.
  • Example 1 represents the wear rate for rotor blades made from a traditional asbestos cloth/phenolic resin laminate.
  • Example 3 represents the wear rate for rotor blades made according to the invention, as just described above.
  • the performance of the material according to the present invention was extremely good, both as regards resistance to wear and to delamination in service.

Abstract

Dans un procédé permettant de fabriquer un article en résine synthétique renforcée par fibres, on forme une suspension aqueuse de fibres en mélangeant intimement les fibres de renforcement dispersibles dans l'eau, on forme une nappe en l'absence de matériau de liaison, puis on produit une préforme fibreuse formée à partir de ladite suspension par une opération de formage sous vide, suivie du séchage de la préforme.
