摘要： There is provided a device for producing fibre-reinforced composite components from dry fibre components by means of an injection process for injecting curable matrix material, comprising a. a tool for arranging a dry fibre component; b. an envelope which is impermeable to gas and curable matrix material arranged on at least one side of the tool to form a space into which curable matrix material may be introduced to contact a dry fibre component arranged on the tool, the envelope sealing off the tool from the environment; c. an inlet for introducing curable matrix material into the space formed by the envelope; d. an outlet for removing gas from the space formed by the envelope so that curable matrix material may be drawn into the space to penetrate the dry fibre component arranged on the tool; and e. a patch formed from a membrane which is permeable to gas but impermeable to curable matrix material, the patch being associated with the outlet so that gas, but not curable matrix material, can be removed from the space formed by the envelope via the outlet; wherein the association between the outlet and the patch is stable at temperatures of at least 150° C. There is further provided a method for producing fibre-reinforced composite components by use of a device according to the invention.

摘要： The invention concerns a process for preparing a ribbon of reinforcement strands or filaments associated on each of its faces with a polymeric binder, said ribbon having a given width substantially constant over its entire length, in which the strands or filaments extend in a direction parallel to the length of the ribbon, wherein it comprises the following steps: a) adjustment of the ribbon width to the desired width thanks to a dimensioning device, b) association of the ribbon on each of its faces with a polymeric binder allowing the assurance of a homogenous cohesion of the ribbon, such that the total weight of the binder does not exceed 25% of the total weight of the obtained ribbon, as well as the ribbons obtainable by such a process.
