Definitions

  • the present invention relates to a composite material.
  • the composite material is a heterogeneous substance generally comprising fibers, threads, free or assembled in layers, embedded in a resin.
  • These composite materials are generally in the form of large, fairly rigid thick plates. They are more and more used in industry, especially in the industry of construction of equipment, capital goods, transport, etc. to make bodywork, floors, etc.
  • a production method consists in assembling in layers or strata textile fabrics of fibers or reinforcing threads with high mechanical characteristics such as: glass, silica, silicon carbide, carbon, ceramic, aramides, high modulus polyethylene, etc., and to drown them in a resin matrix.
  • a base of resin and release agent is poured into a mold the size of a plate; above, a first layer of fabric is placed, made of reinforcing fiber threads for example, which is covered with resin; above, a second layer of fabric is placed in high-resistance reinforcing threads, which are also covered with resin; so on, several layers are stacked, for example five or six which are covered with resin, and the stacking is completed with a last layer of resin and a release agent.
  • This assembly is then subjected to a compression action intended to eliminate the maximum of air and to make the resin penetrate into the layers of fabrics, then a heat treatment which crosslinks or polymerizes the resin in order to obtain a rigid composite and the most homogeneous whole possible.
  • These composite materials can comprise up to more than forty layers each with a thickness of the order of 0.1 to 0.2 millimeters; the most common have from one to fifteen layers and are of average total thickness between 3 and 5 millimeters after compression and ready to use. Their weight is around 200 grams / m2 for a 0.1 mm thick layer of glass.
  • the material obtained is a composite product with high resistance, in particular to impact, traction, compression.
  • a fabric is a textile structure formed by an assembly of so-called warp threads assembled in so-called weft threads.
  • This structure extends in a plane, the thickness of which is limited to that of the wire or wires used, dimension negligible in relation to the surface of the fabric.
  • One of the usual characteristics of fabrics is their non-deformability in plan, which can be a quality or a defect depending on the use made of them. It is well known that the deformation of a fabric to give it a shape produces folds, the fabric not being capable of deforming elastically due to its structure. Confection is then the art of assembling pieces of fabric so as to hold forms, whether in the clothing industry or any other industry. This is why, when making composite materials, assembling the layers of fabrics also consists in arranging strips of fabrics so as to promote the production of shapes, without producing folds.
  • the document EP 0 258 102 describes a laminated material having a cross section of the type comprising a core and at least one lateral wing, for example an I, T, J section, or the like. Said material is obtained by impregnating a textile structure for strengthening and hardening the assembly. Said textile structure is of the type comprising two plies A, B, woven, spaced from one another, and a connecting ply C extending between these two plies A, B. Said connecting ply C consists of at least one ply of tying warp threads, trapped between the weft threads of the two woven plies A, B.
  • the aim of the present invention is to produce a composite material according to a process which solves all of the difficulties described: mechanization, speed of production, high deformability, resistance to delamination, homogeneity, costs.
  • the subject of the invention is a material produced from threads previously associated with a thermoplastic resin, in which the threads are assembled in the form of a thick fabric comprising several series of warp threads extending parallel to one another and being vertically overlapping to form a thick sheet which extends in three dimensions, characterized in that that weft threads are passed alternately through warp threads of different levels (2a, 2b, 2c) so as to impart great deformability to the fabric with a view in particular to allowing it to be wound up.
  • the subject of the invention is also a method of manufacturing armor plates or the like for the production of bodies, floors or the like, from a material according to the invention, characterized by a step of heat treatment in a mold followed by a stamping step.
  • the fabric 1 comprises several series of 2 warp threads 2 extending parallel to each other.
  • the fabric has 5 series of warp threads 2a to 2e.
  • Each chain is horizontal, the series overlap vertically, forming a thick sheet, which extends in the three dimensions.
  • the weft threads 3 are passed alternately through these warp threads and, depending on the choice, alternate between the thread of the first level 2a and the thread of the second 2b, or of the third 2c etc.
  • the weaving can be modulated according to the effect which one wants to give to the fabric.
  • the threads are previously associated with the resin, that is to say that they comprise both reinforcing fibers and their matrix or resin.
  • This "entrainment” is obtained either by intimate mixing in the wire, of reinforcing fibers and of resin presented in the form of fibers, or by coating of reinforcing wires with a sheath of resin.
  • the weaving is carried out with threads comprising only reinforcing fibers, free of resin.
  • the son-resin association, or “enresinement” is here a coating of the fabric; it is produced after passing through the loom by application with a brush, spraying, injection, or any other known technique.
  • the first variant is advantageous in that it gives in a single operation a flexible material which can be immediately rolled up, or cut into panels, and constitutes a finished product ready to be used.
  • the coating obtained must then undergo a heat treatment followed or not by compaction intended to melt the resin, to give this coating the desired shape and then to give it great rigidity.
  • a three-dimensional fabric was produced with composite yarns of 60% glass, 40% PEEK, and the heat treatment and stamping gives armor plates.
