Definitions

  • This invention relates to composite materials and a method of manufacture of such composite matenals.
  • VOC's volatile organic compounds
  • resm film infusion where a film or a slab of uncured resin m placed m communication with a preform. The application of heat and pressure melts the resm, which then infuses into the preform and subsequently cures.
  • the method utilises the advantages of closed mould techniques, namely the production of near net shape parts with controlled emissions of VOC's, without the disadvantages of conventional routes used to manufacture composites with vanable properties through its thickness.
  • a fibre reinforced composite compnsmg a fibre reinforcement layer having a first matnx located from a first surface of the fibre reinforcement layer to a depth only partially through the fibre reinforcement layer and a thermoset resm matnx located from a second surface of the fibre reinforcement layer only partially through the fibre reinforcement layer.
  • the first matnx matenal may be a thermoplastic or a thermoset.
  • the two resm matrices may fully wet the fibre reinforcement layer.
  • further matnx matenals may also be present in the final composite. These may be incorporated an infusion or an injection process. If the further matnx matenals are to be infused, they may be positioned where desired within the fibre reinforcement layer, pnor to the infusion step.
  • the further matnx matenals may be injected either pnor to the injection of the second matnx material or after it, depending on the properties required in the final composite matenal.
  • This enables the final composite to not only have a difference in properties between the first surface and the second surface but, also a difference at the first surface and a desirable point between the first surface and the second surface.
  • An example of this is when the first layer of matnx matenal at the first surface is cosmetic, the second layer compnses a fire retardant, and the subsequent layer imparts structural support.
  • the matrices may be the same.
  • the vanation of properties through the thickness of the composite would be achieved by a difference m the cunng cycle of the resm used in each stage. For example, if the resin were high temperature cure and the first matnx matenal were heated m order to facilitate cunng, by cooling pnor to the injection of the second matnx then, heating the fibre and resin on injection, the first matnx would be post cured, resulting m a difference m properties between the first and second matrices.
  • a method of manufacture of fibre reinforced composite matenals compnses the steps of providing a fibre reinforcement layer, providing a first matnx adjacent to a first surface of the fibre reinforcement layer, enclosing the fibre reinforcement layer and first matrix in an envelope and injecting a second matrix matenal into the envelope, the second matrix material being a thermoset resm matrix, whereby the second matrix infuses into the second surface of the fibre reinforcement layer
  • Further matnx matenals may be present in the final composite and can be incorporated either dunng the same infusion process as the second matnx material or m a separate step This would enable the final composite to not only have a difference in properties between the first surface and the second surface but, also a difference at the first surface and at least one desirable point between the first surface and the second surface
  • the second matnx matenal is preferably a liquid of low viscosity to enable injection and infusion throughout the dry portion of the fibre reinforcement layer pnor to the cunng of the material.
  • Suitable thermoset matenals include polyesters, epoxies, phenohcs, vmyl-esters, acrylics, bismaleimides Whichever suitable matenal is chosen would depend on the properties required the final composite.
  • the first matnx matenal is a thermoplastic and the method includes the additional step of heating the first matnx matenal prior to injection of the second matnx matenal.
  • the temperature and duration of the heating would be determined by the thermoplastic matenal used and the degree of infusion of the thermoplastic through the fibre reinforcement layer from the first surface that is required.
  • the fibre reinforcement layer is cooled pnor to the injection of the second matnx matenal. This allows for better control of the degree of infusion by the first matnx.
  • the first matnx matenal is a thermoset resm which is preferably in a solid or highly viscous form at ambient to enable correct placing of the matnx material with respect to the fibre reinforcement layer and enclosure of them under the envelope.
  • the first matnx matenal is a high temperature cure thermoset resm.
  • the fibre reinforcement layer and first matnx matenal are preferably heated. The temperature chosen will depend on the resm system used and the required degree of cure.
  • the fibre reinforcement layer and first matnx material are cooled after the required degree of cure of the first matnx matenal has been achieved. This would allow the first and second resm matrices to chemically react and so produce a strong bond between the different layers.
  • the fibre reinforcement layer is heated to a suitable temperature either pnor to or dunng injection of the subsequent matnx matenal. The temperature being maintained until the resm has reached the desired degree of cure This step would occur after the cooling step.
  • the second matnx matenal is preferably different to the first matnx matenal.
  • care would be required in order to produce a high quality composite.
  • One problem that could be encountered is the presence of residual stresses m the composite as a result of a difference in shnnkage percentages and rates of the matnx matenals.
  • the properties required m the composite may be inherent m the matnx matenal itself or, may be imparted or augmented by the use of a suitable filler matenal.
  • a distribution means may be positioned between the fibre reinforcement layer and envelope. This is particularly useful if the shape of the composite is complex.
  • a distribution means between the envelope and the fibre reinforcement layer enables fast distnbution of the matnx matenal to all parts of the dry reinforcement layer. Another advantage of utilising a distribution means is that the infusion time of the subsequent matnx matenal is reduced, thus allowing it to be cured more quickly so reducing the time to manufacture each part.
  • the envelope is subject to a vacuum pnor to injection of the second matnx matenal.
  • a vacuum would allow any gases produced to be removed from the envelope for example if the cunng of a thermoset resm results in a condensation reaction.
  • the use of a vacuum would also allow for faster distribution of the matnx matenal through the fibre reinforcement.
  • the envelope is preferably flexible.
  • An alternative to subjecting the envelope to a vacuum would be to inject the second matnx matenal under pressure. If the second matnx matenal is subject to a pressure dunng injection, the envelope is preferably rigid.
  • the envelope is subject to additional pressure during the injection of the subsequent matnx matenal.
  • This pressure may be maintained until the subsequent matnx matenal has cured. This enables more accurate control of the thickness and the volume fraction of fibre of the composite being manufactured. This is especially useful when a large number of components are being manufactured and reproducibihty is important.
  • the additional pressure may also assist m the infusion of the subsequent matnx material into the dry portion of the fibre reinforcement layer.
  • the fibre reinforcement layer compnses a plurality of dry plies. These plies may be stitched.
  • the type of reinforcement, its onentation and the volume fraction desired in the final composite will be a function of the property requirements of the composite when m use.
