Definitions
- the present invention relates to a method and an installation for producing a multidirectional fibrous web.
- multidirectional fibrous plies formed by the superposition of several unidirectional fibrous plies arranged in different directions and interconnected.
- Each unidirectional sheet is formed of fibers which are oriented in a direction and generally along the longitudinal axis of said sheet.
- This type of ply is obtained for example by cracking, carding, converting or drawing with or without a bar of at least one cable, for example of carbon.
- a commonly used technique consists in giving the fibers sufficient cohesion in order to avoid their dispersion.
- One of the means for giving this cohesion to the fibers of the unidirectional sheet consists in binding them together by threads arranged in a weft or by sewing.
- the main drawback of these techniques lies in the fact that the bonding wires create extra thicknesses forming corrugations which can lead to the crushing and breaking of the fibers of the unidirectional sheets during the superposition and pressing of these sheets against each other. .
- the breaking of the fibers can result in a degradation of the multidirectional layers and consequently harm the mechanical properties of the parts in composite material obtained from these multidirectional layers.
- binding wires made of hot-melt material which at least partially melt during the production of the composite material, which makes it possible to reduce the excess thicknesses.
- the material making up the bonding yarns be compatible with the nature of the matrix of the composite material, which limits the use of this technique.
- Another technique also: employed consists in giving cohesion to the fibers of the unidirectional sheet by a slight intermingling of these fibers by the application on this sheet of a jet of water or by needling.
- the application of a jet of water or needles can cause local disorganization of the fibers of the unidirectional sheet by creating holes which can adversely affect the mechanical properties of the parts made of composite material.
- Another solution consists in giving cohesion to the fibers of the unidirectional sheet by the addition of a chemical bonding agent which may be eliminated, for example by spraying a liquid composition onto the sheet or passing through a bath.
- a chemical bonding agent which may be eliminated, for example by spraying a liquid composition onto the sheet or passing through a bath.
- such a technique increases the cost price of the unidirectional sheet.
- the object of the invention is to avoid these drawbacks by proposing a method and an installation for producing a multidirectional fibrous web from unidirectional fibrous webs which can be handled before they are superimposed and which have good surface regularity.
- the subject of the invention is therefore a process for producing a multidirectional fibrous web, in which several unidirectional fibrous webs are superimposed in different directions and said unidirectional webs are connected together, characterized in that:
- the fibers of this ply are maintained on the support strip, the unidirectional ply is separated from the support strip,
