The work of preparing International Standards is normally carried out through ISO technical

12、 committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with

13、 the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of th

14、e member bodies casting a vote. International Standard ISO 2113 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This second edition cancels and replaces the first edition (ISO 2113:1981), which has been technically revised.BS ISO 2113

15、:1996 BSI 21 July 2003 iii Introduction A basis for a specification is intended to give guidance on the establishment of technical specifications for products of a given type. It should enumerate as completely as possible the points that should be considered at the time of drafting the specification

16、s. The basis for a specification, therefore, does not in itself constitute a specification, but rather a model plan for the elaboration of specifications applying to a particular product, or to a family of products whose characteristics are closely related. These specifications may be established by

17、 a producer, supplier or user, or by a standardization organization.iv blankBS ISO 2113:1996 BSI 21 July 2003 1 1 Scope This International Standard provides a basis for a specification applicable to fabrics woven from yarns (including single yarns, multiple-wound yarns, plied yarns, cabled yarns and

18、 rovings) made from textile glass, carbon or aramid and generally used for plastics reinforcements. This International Standard does not cover all requirements for some specialized applications. If such other requirements are necessary, they are given, or will be given, in other International Standa

19、rds. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on

20、 this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

26、or at some other specified angle, such interlacing being carried out by during weaving on a loom or weaving machine 3.2 warp yarns lying in the lengthwise direction of the fabric (0 direction) 3.3 weft yarns running from selvedge to selvedge, generally at right angles to the warp (90 direction)BS IS

27、O 2113:1996 2 BSI 21 July 2003 3.4 type of weave designation of the method of interlacing warp and weft to give a regular, repeating pattern of weaving, e.g. plain, satin, twill, etc. 3.5 construction the number of yarns per centimetre length in the warp and weft directions NOTE The term is also use

28、d with reference to the type of weave. 3.6 tracer yarn a yarn of different colour and/or different composition from the reinforcement yarns, which is included in the fabric for product identification or to aid fabric alignment during moulding 4 Types Technical description of woven reinforcement fabr

29、ics The technical description of a woven reinforcement fabric requires definition of the following points: a) the designation of the yarns in the warp direction; b) the designation of the yarns in the weft direction; c) the construction of the fabric: 1) type of weave; 2) weave ratio; 3) number of y

30、arns per centimetre in warp and weft; d) the type of treatment and/or size content, if applicable; e) the mass per unit area. As the full description is unwieldy, woven reinforcement fabric manufacturers normally give a code number to their fabrics to simplify ordering and stocking. The full descrip

31、tion of the woven fabric shall, however, be given in the manufacturers catalogue against its code number. Though this technical description is not necessary for the designation of fabrics, it may be used as a guide to the establishment of descriptions in the reinforcement fabric catalogues, so ensur

32、ing a strong basis for identification of fabrics. For the designation of textile yarns, see ISO 2078. NOTE 1 The designation of carbon fibres will be covered in a future International Standard, ISO 13002, Carbon fibres Designation. 5 Sampling and number of test specimens Each delivery of a given typ

33、e of fabric shall be sampled in accordance with ISO 2859-1 and ISO 3951. For the verification of visual properties, each roll selected as part of the sample shall be examined along its whole length except where otherwise specified. For the physical properties, take, from each roll selected, a labora

34、tory sample, after removal of at least the outside layer of the roll. The specification may stipulate that more than one laboratory sample has to be taken from each roll. The number of test specimens taken from each laboratory sample shall be as specified for each test method. 6 Conditioning The spe

35、cification shall supply the information required for the proper conditioning of the elementary units (rolls of fabric). In the absence of specific instructions for the fabric under consideration, it shall include a reference to ISO 139 or ISO 291. When required, specific conditioning instructions fo

36、r the laboratory samples or test specimens shall be as given in each test method.BS ISO 2113:1996 BSI 21 July 2003 3 7 Characteristics and test methods 7.1 General Woven reinforcement fabrics shall be of uniform structure.

45、ccordance with: ISO 1887 for glass-fibre fabrics; a suitable method for carbon-fibre fabrics. For fabrics manufactured from other reinforcement yarns or mixed fibres, the specification shall provide suitable instructions. The results shall be expressed as a percentage by mass of the dried fabric, to

46、 the nearest 0,1 %. 7.2.4 Tracer yarn If the fabric contains a tracer yarn, the following shall be identified: a) the type; b) the linear density; c) the warp spacing; d) the weft spacing. 7.2.5 Mechanical characteristics 7.2.5.1 Tensile strength and elongation at break The tensile strength and elon

47、gation at break of the reinforcement fabric shall be determined in accordance with ISO 4606 in both the warp and the weft directions. The results shall be expressed in newtons to the nearest 1 % for the tensile strength and as a percentage to two decimal places for the elongation. 7.2.5.2 Stiffness

48、The stiffness of the reinforcement fabric shall be determined in accordance with the fixed-angle flexometer method specified in ISO 4604. The stiffness shall be determined in both the warp and the weft directions. The results shall be expressed in millinewton metres. 7.3 Defects Any or all of the fo

49、llowing defects may be excluded by agreement between the interested parties. 7.3.1 Warp defects a) Ends out: a gap caused by a missing warp yarn. b) Misreed (wrong denting): a place in the fabric where one or more ends are not properly placed in the reeds. c) Tight end: a single end woven under excessive tension. d) Slack end: an end woven under insufficient tension. e) Slack selvedge. f) Tight selvedge. g) Fuzzy ends/fuzz b
