Definitions
- the invention relates to technical fabrics having remarkable fire resistance properties.
- the invention also relates to articles comprising such a fabric, in particular the articles obtained by impregnating these fabrics with the aid of a resin, and optionally in combination with other constituents, thereby producing structures having domains of very varied applications, for example in the aeronautical industry and in all cases where products with high fire resistance are sought.
- the patent FR 85.15.328 relates to a fabric based on fibers, having a high fire resistance, a low weight per unit area and a good mechanical strength, characterized in that it comprises a mixture of 50 approximately 90% by weight of textured glass fibers and approximately 10% to 50% by weight of carbon fibers.
- a fabric is well suited, by impregnation with residual resins, advantageously phenolic resins, for the production of articles such as parts for the interior fittings of aircraft, which must simultaneously fulfill a certain number of requirements. obtain honeycomb structures capable of meeting the most stringent and latest standards in the aeronautical industry.
- the first constituent of the fabric according to the invention consists of textured fire-retardant fibers.
- the expression “textured” within the meaning of the present description designates a fiber whose alignment of each filament is random.
- frayed fibers This type of fiber is known to a person skilled in the art and can be obtained in a known manner by various treatments.
- the textured fibers used in the fabric according to the invention are continuous or discontinuous. Continuous fibers are generally preferred, which provide the best results when sizing.
- the textured fibers of the fabric according to the invention have the property of being "fireproof", an expression which means that they are classified at least M1 and preferably M0 according to French standard NF P 02-507 (October 1975) entitled “Classification of materials used in construction”, established in accordance with the Decree of June 4, 1973 (Official Journal of July 26, 1973) and published by the French Association for Standardization (AFNOR), Tour Europe, Paris La Défense. Fire tests of materials, such as the fabrics according to the invention, are carried out according to standard NF P 92-503 (October 1975).
- fire-retardant fibers are those which, according to the classification which has just been mentioned , are classified M0 or M1.
- the second constituent of the fabric according to the invention consists of technical fibers which have sufficient rigidity characteristics and which, in combination with the fibers a), provide the fabric with overall fire resistance properties making it possible to meet the aforementioned standards.
- the expression "rigidity greater than that of textured glass” means that the fibers b) have a tensile modulus greater than approximately 55,000 MPa.
- the preferred fibers, which have such properties at the same time as satisfactory fire resistance are carbon fibers, aramid fibers and silicon carbide fibers. When carbon fibers are used, they most commonly have 1000 to 6000 filaments, for example around 3000 filaments.
- the relative proportions of the two constituents of the fabric according to the invention will be chosen according to the precise problems to be solved. It is indeed necessary to take into account a certain number of parameters such as the unit mass, the fire resistance properties, the overall mechanical characteristics and the price of the final fabric.
- the fibers a) have the essential characteristic of being textured, which has many advantages compared to similar non-textured fibers. These avan tages are particularly apparent when, as is preferred, the fabric according to the invention is used for the manufacture of composite materials, by impregnating the fabric, formed into layered layers in an appropriate number, with a resin, such as a resin phenolic.
- the resin impregnation rate can be high and in general it is from 30 to 60%, in particular from 50 to 60%.
- Textured fibers make it possible to obtain articles having a better surface condition, since they have a significantly higher resin absorption capacity than the corresponding fibers which are non-textured or smooth. Also textured fibers provide a better fiber / resin interface, because they provide a larger contact surface with the resin. Furthermore, fabrics and articles based on textured fibers have a low surface mass, due to the "swollen" structure of said fibers.
- the use of fibers a) textured in the fabrics according to the invention makes it possible to eliminate the harmful effect of the difference in expansion. between fibers a) and fibers b).
- the textured fibers a) present a random distribution of the filaments which is favorable to the compensation of the dilations.
- the non-textured fibers, mixed with the fibers b) can cause warping and deformations in the finished articles, obtained after resin impregnation.
- the fibers which fall into category a) and are preferred by the invention are glass fibers.
- textured fibers have a weight per unit length which can vary within fairly wide limits, in particular 11 to 126 tex (1 tex represents the number of grams per kilometer of fibers).
- Other examples of fibers which can be used are textured aramid fibers, for example those available on the market under the name "Kevlar" type 49 and which have undergone a prior texturing treatment.
- examples of fibers b) are carbon fibers, aramid fibers and silicon carbide fibers.
- the fibers b) can be chosen individually from carbon fibers, aramid fibers, silicon carbide fibers, but any combination of such fibers can also be used, such as carbon and aramid fibers, carbon fibers and silicon carbide, aramid fibers and silicon carbide and other analogous combinations.
- the fabrics according to the invention can be used for the manufacture of any pieces which can be obtained by resin impregnation and molding. It is thus possible to produce laminates comprising several layers of fabrics impregnated with resin, for example two or three layers. It is also possible, as is known in the art, to impregnate a fabric according to the invention with a resin such as a phenolic resin and to stick it on one side or on both sides of a honeycomb structure. bees. Sandwich structures are thus produced with greater inertia. These manufacturing techniques are known to those skilled in the art and need not be explained further. useful purposes, one can refer for example to the work "Practical guide of composite materials" 2nd edition (1985) by M. Geier and D. Duedal Editions Lavoisier (France).
- the articles and structures comprising the fabrics according to the invention can find very varied applications, whenever products with sufficient fire resistance are needed. Outside the aeronautical field, one can also cite that of construction, such products being usable for the interior fitting out of performance halls, public places and others.
- a base mixture was used containing, by weight, 67% of textured glass fibers and 33% of aramid fibers ("Kevlar" type 49).
- the textured glass fibers had a weight per unit length of 34 tex.
- a fabric was woven from this mixture of fibers, the mechanical characteristics of which were as follows, as measured on laminated samples for laboratory tests, comprising 12 layers of impregnated fabric, so as to produce specimens of 3 mm in diameter. thickness. Flexural strength: 340 Mpa Flexural modulus: 27000 MPa Shear strength: 30 MPa The impregnation resin was a modified phenolic resin (Vicotex 250 from Brochier SA) at a rate of 55%.
- Example 2 a fabric was produced in all points similar to that of Example 1, but by replacing the aramid fibers with the same proportion (33%) of silicon carbide fibers SiC, Nicalon type.
