14、ember bodies). The work of preparing International Standards is normally carried out through ISO technical 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, governm

15、ental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Dir

16、ectives, Part 3. 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 the member bodies casting a vote. Attention is drawn to the possibility that some of the e

17、lements of this part of ISO 1268 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 1268-6 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. I

20、 moulding compounds Small platesINTERNATIONAL STANDARD ISO 1268-6:2002(E)1 Fibre-reinforced plastics Methods of producing test plates Part 6: Pultrusion moulding 1 Scope This part of ISO 1268 specifies a pultrusion-moulding method for preparing reinforced plastics test plates to be used for the prep

21、aration of test specimens to determine the mechanical and physical properties of the laminate. The method is applicable to laminates made from thermosetting or thermoplastic resins reinforced with glass, carbon or aramid fibres alone or in combination and in any form suitable for the pultrusion proc

22、ess (continuous rovings, tows, mats, fabrics or combinations of these). This part of ISO 1268 is intended to be read in conjunction with ISO 1268-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part o

23、f ISO 1268. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 1268 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated b

24、elow. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 1172, Textile-glass-reinforced plastics Prepregs, moulding compounds and laminates Determination of the textile-gl

25、ass and mineral-filler content Calcination methods ISO 1268-1, Fibre-reinforced plastics Methods of producing test plates Part 1: General conditions 3 Health and safety See ISO 1268-1. 4 Principle 4.1 The pultrusion process is unique among processes for the manufacture of fibre-reinforced composites

26、 in being able to produce continuous lengths of profile with complex geometry and different fibre content, orientation and type of reinforcement material within the profile. Satisfactory performance in service can depend on the properties of parts of the profile which are too small or of an unsuitab

27、le shape for their properties to be verified by cutting test specimens from the profile. If test specimens meeting the required test conditions cannot be obtained from the production profile, it is necessary to produce a representative flat strip laminate made from the same materials and under the s

28、ame processing conditions as the production laminate. Test specimens may then be cut from the representative flat strip in accordance with the relevant mechanical test method. This part of ISO 1268 defines a procedure for the manufacture of such representative laminates. The method may also be used

29、to compare the performance of alternative input materials and alternative profile production conditions. 4.2 The reinforcement is impregnated with a suitable resin and pulled through a forming die, under specified conditions, to consolidate the matrix system and form a flat strip profile.ISO 1268-6:

30、2002(E) 2 The flat strip profile has to be of sufficient width to allow test specimens of the requisite length to be cut perpendicular to the direction of production or in other specified directions. 5 M a t e r i a l s 5.1 Reinforcement materials, in any form suitable for the pultrusion process, in

31、 most cases continuous rovings, tows or strands, mats and woven fabrics, with surface treatment compatible with the resin system used. 5.2 Either a thermosetting resin system, formulated in accordance with the suppliers instructions, that will perform adequately at the selected processing conditions

32、 of temperature, production speed, etc., resulting in a cured matrix system, or a thermoplastic matrix, in which case the nature and form of both the matrix polymer and the reinforcement may be specific to the system being used to make the test plates. 6 Shape and dimensions For the purposes of this

33、 part of ISO 1268, only flat strip profiles are acceptable for the production of test plates. The permitted width and thickness of the plate will depend on the purpose for which the plate is made. In all cases, the thickness shall be the thickness required in the final test specimens. The width of t

34、he plate shall be sufficient to allow test specimens of a length suitable for the test being undertaken to be cut perpendicular to the direction of production. 7 Reinforcement content The reinforcement content, the nature of the reinforcement and the orientation of individual layers in the laminate

35、shall be as defined in the specification for the test plate or by the person ordering the production of the test plate. In all cases, there shall be sufficient reinforcement included to completely fill the die cavity. 8 Apparatus 8.1 Pultrusion equipment consisting of the following. 8.1.1 Reinforcem

36、ent rack or creel to hold the required number of roving ends and, optionally, the required rolls of mat, fabric, etc. 8.1.2 Impregnating unit. 8.1.3 Forming die for the selected profile, equipped with a suitable heating system (it is sometimes possible to combine the forming die and the impregnating

37、 unit). 8.1.4 Pulling section, designed to adequately pull the selected profile at constant speed. 8.1.5 Cutting section. 8.1.6 Clamp or press, suitable for holding the test plates while they stabilize and/or while they are post-cured. 9 Procedure For general conditions, see ISO 1268-1. The equipmen

38、t shall be set up in accordance with the manufacturers instructions. The reinforcement content, the nature of the reinforcement and the orientation of individual layers in the laminate shall be as defined in the specification for the test plate or by the person ordering the production of the test pl

39、ate. TheISO 1268-6:2002(E)3 process conditions shall be chosen in accordance with the recommendations of the resin supplier, to obtain a cured product free of defects, reflecting the standard production quality for such pultruded products. The test specimens shall be cut from the profile only when s

40、table process conditions have been achieved. 10 Stabilization The test plate shall be flat and fully cured to enable satisfactory test specimens to be cut from it. Depending on the resin being used and the process conditions, the flat profile produced by the pultrusion machine may require a period o

41、f stabilization and/or post-cure. The test plate shall be cut to approximately the right length on the pultrusion machine and (if stabilization is required to prevent warping) the plates shall be held flat in a suitable clamp or press. If post-curing is required, this shall be done while the plates

42、are held in the press. The time and temperature of the post-cure shall be as defined in the process specification or by the person ordering the production of the test plate. 11 Verification of the characteristics of the test plate The fibre content shall be determined by the method given in ISO 1172

43、 for glass fibre, or by a method agreed between the interested parties for carbon fibre, and compared to the requirement given in the specification. The void content shall be assessed visually before submitting the test specimens for testing. 12 Test plate preparation report The test plate preparati

44、on report shall include the following information: a) a reference to this part of ISO 1268; b) a full description of the constituents used, including the resin system, the reinforcement and any addivities (product codes and/or generic descriptions may be used as applicable); c) identification of the

45、 plates, using a suitable numbering or code system; d) a record of the production process conditions, including as a minimum the peak die temperature and the pull speed; e) details of the conditions of any post-cure; f) the reinforcement content; g) any modifications to the procedure which might inf
