This European Standard shall be given the status of a national standard, either by publication of an identical text or
15、 by endorsement, at the latest by December 2001, and conflicting national standards shall be withdrawn at the latest by December 2001. This standard is one part of EN 13473, Reinforcement Specification for multi-axial multi-ply fabrics, which is constructed as follows: Part 1: Designation; Part 2: M
16、ethods of test and general requirements; Part 3: Specific requirements. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, German
17、y, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 4 EN 13473-1:2001 BSI 07-2001 1 Scope This part 1 of EN 13473 establishes a method of designation for multi-axial multi-ply fabrics that shall be used for specificati
18、ons for the reinforcement of materials. The method of designation defines the structure of the multi-axial multi-ply construction and the binding system. This designation system applies to multi-axial multi-ply fabrics made of reinforcement yarns, tows, rovings, fibre fleeces, films, foams or other
19、materials which are intended to provide reinforcement in composite materials and which is bound to a multi-ply construction. The designation of a multi-axial multi-ply fabric is structured in a product of multi-axial multi-ply fabrics. It is not intended that this hierarchy takes into account all th
20、e attributes of individual multi-axial multi-ply fabrics. Therefore multi-axial multi-ply fabrics having the same designation do not necessarily give the same performance. This part 1 of EN 13473 does not give engineering data, performance data or data that may be required to specify multi-axial mul
21、ti-ply fabrics for a particular application or method of processing. If such additional properties are required they have to be determined in accordance with the test methods specified in EN 13473-2. 2 Normative references This European Standard incorporates by dated or undated reference, provisions
22、 from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by ame
23、ndment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

25、given in ISO 472, EN 13473-2 and the following apply. 3.1 multi-axial multi-ply (not woven) fabric textile structure constructed out of one or more laid parallel non-crimped not-woven thread plies with the possibility of different orientations, different thread densities of the single thread plies a
26、nd possible integration of fibre fleeces, films, foams or other materials, fixed by loop systems or by chemical binding systems. The threads can be oriented parallel or alternating crosswise. These products can be produced on machines with insertion devices (parallel-weft or cross-weft) and warp kni
27、tting machines or chemical binding systemsPage 5 EN 13473-1:2001 BSI 07-2001 3.2 ply construction textile structure constructed out of one or more laid parallel non-crimped thread plies, which is differently oriented, with different thread densities of the single thread plies and in which integratio
28、n of fibre fleeces, films, foams or other materials is possible. The orientation of the single thread plies is related to the production direction of 0. The description of the orientation of the thread plies is derived from ISO/DIS 1268-1:1997 using the angle orientation (90 maximum angle) which is
29、defined as follows: The thread plies oriented in the range between 0,90 are described as “+” or “-”-direction in relation to 0. The orientation is defined as “+”, if the threads are oriented in quadrant “+”, respectively “-”, if the threads are laid in quadrant “-” (see Figure 1). Key 1 y 90 2 z dir

32、oop according to ISO 4921 3.3.2 chemical binding fixing by chemical means of adhesive binder 4 Designation 4.1 General The designation for multi-axial multi-ply fabrics is based on the following standardized pattern. This standardized pattern is a modification of the frame text given in ISO 1043-2,
33、adapted to the designation of the multi-axial multi-ply fabrics. Table 1 Designation system Designation Identity-Block Individual-Item-Block International Standard Data-Block 1 Data-Block 2 Data-Block 3 Example EN 13473-1, . . . The design consists out of an Identity-Block comprising the European St
34、andard Numbers and an Individual- Item-Block. For unambiguous coding the Individual-Item-Block is subdivided into 3 Data-Blocks. To ensure legibility: the Individual-Item-Block shall be separated from the Identity-Block by a “comma (,)”; the 3 Data-Blocks of the Individual-Item-Block are framed by “
35、rectangular brackets (.)”; if a Data-Block is not used, this shall be indicated by empty “rectangular brackets ()”. The three Data-Blocks are comprising the following information: Data-Block 1: Identification of the ply construction ; Data-Block 2: Identification of the binding system ; Data-Block 3
36、: Identification of the multi-axial multi-ply fabric manufacturer.Page 7 EN 13473-1:2001 BSI 07-2001 4.2 Data-Block 1 This Data-Block describes the ply construction. The description of the single plies are separated by a “double slash (/)”, starting with the first ply due to the production successio
37、n (see Figure 1). Each single ply description consists out of 3 positions. The three positions of the single ply description are separated by a “comma (,)”. In position 1 of the ply description the material types and grades used in this ply are identified by code letters according to Table 2. In the
38、 case of combinations of different materials (hybrid materials), the different materials and grades have to be identified by their abbreviation with each constituent separated by a “slash (/)”. For each constituent the abbreviation shall be followed by a number equal to the percentage content by wei
39、ght rounded to the nearest 1 %. The materials need to appear in descending order of their content by weight in the single ply. Table 2 Abbreviation for materials types Code Letter Material Type AA r a m i d e C Carbon GG l a s s K Ceramic PA Polyamide PE Polyethylen PES PET Polyester/ Polyethylenter
40、ephtalat PP Polypropylene NOTE Supplements of further material types are possible. The material grades have to be aditionally specified in each case. In position 2 of the ply description the mass per unit area of the single ply is identified by a number equal to the mass in grams per square metre. P
41、osition 3 is indicating the orientation of the thread plies in case of the use of reinforcement fibres or the material description in case of the use of cover or inlay plies (see ISO 1043-2). For alternating crosswise oriented thread plies the two different orientations of the threads in one single
42、layer are described by the two thread orientations divided by a single “slash (/)”. 4.3 Data-Block 2 In this Data-Block the binding system is defined and described by 3 Positions. Positions 1, 2 and 3 are separated by a “comma (,)”. In position 1 of the binding description the material types and gra
43、des used are identified by abbreviation according to Table 2. In the case of combinations of different materials (hybrid materials), the different materials and grades shall be identified by their abbreviation with each constituent separated by a “slash (/)”. For each constituent the abbreviation sh
44、all be followed by a number equal to the percentage content by weight rounded to the nearest 1 %. The materials shall appear in descending order of their content by weight. In position 2 of the binding description the mass per unit area of the binding is identified by a number equal to the mass in g
45、rams per square metre. In position 3 of this Data-Block the binding type is identified by letters according to Table 3.Page 8 EN 13473-1:2001 BSI 07-2001 Table 3 Code letter for the type of the binding system Code letter Type of binding system L Loop system C Chemical binding system 4.4 Data-Block 3
