The work of preparing Internatio

16、nal 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, governmental and non-governmental, in liaison with ISO

17、, 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 Directives, Part 3. Draft International Standards

18、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 elements of this part of ISO 1268 may be the sub

19、ject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 1268-5 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This first edition cancels and replaces ISO 9291

20、:1996, which has been technically revised. ISO 1268 consists of the following parts, under the general title Fibre-reinforced plastics Methods of producing test plates: Part 1: General conditions Part 2: Contact and spray-up moulding Part 3: Wet compression moulding Part 4: Moulding of prepregs Part

23、s part of ISO 1268 specifies a method of preparing reinforced-plastic test plates by the filament winding process, using textile glass rovings and themoset resins (preimpregnated fibres are excluded). It specifies the preparation, under optimum industrial conditions, of unidirectionally reinforced p

24、lates, from which test specimens for various static mechanical tests can be cut. This part of ISO 1268 has been established for glass-reinforced plastics made of polyester or epoxy resin, but it can be extended to other types of resin and reinforcement. It is intended to be read in conjunction with

25、ISO 1268-1. NOTE To aid understanding of the method, the word “roving” is used throughout the text and is taken to include yarns, unless specifically mentioned to the contrary. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitut

28、ions. 3 Health and safety See ISO 1268-1. 4 Principle A roving (or a number of rovings together) impregnated with resin is wound, in several successive layers, onto a former. The required final thickness of the plates is obtained by strapping outer-mould pieces onto the former. Polymerization can be

29、 carried out either in a press with heated platens or in an oven. This method leads to the preparation of two similar plates simultaneously.ISO 1268-5:2001(E) 2 ISO 1002 All rithgs rreseved 5M a t e r i a l s 5.1 Roving This method applies to all rovings having a linear density between and . For low

30、er linear densities, use several rovings in combination to reach a linear density between and (for example, 10 yarns of to obtain ). 5.2 Resin system It is recommended that the resin system used (polyester or epoxy resin + catalyst or hardener system) has the following characteristics: viscosity: le

31、ss than at the winding temperature; minimum pot life: the minimum pot life of the resin system at the operating temperature should be such that the increase in viscosity of the resin at the end of the winding operation is less than of the initial value. If a resin system that does not have the above

32、 characteristics is chosen, the viscosity and minimum pot life of the resin system used shall be stated in the test plate preparation report (clause 11). 6 Plate dimensions The minimum dimensions of the plates produced are in length and in width. 7 Reinforcement content The glass content shall be sp

33、ecified by the person requesting the plate. The glass content of this type of laminate is typically by mass. NOTE A glass content of by mass corresponds to by volume. 8 Apparatus 8.1 Reel (optional) The reel shall be fitted with a tension-regulating system permitting adjustment of the roving tension

34、 between and (tension measured before the roving enters the impregnating bath). 8.2 Winding machine (see Figure 1) The winding machine shall have the following characteristics: speed of spindle: continuously variable from to ; pitch: adjustable from to (the pitch is equal to the travel of the thread

35、 guide when the former makes a complete revolution); when necessary, a radiant panel permitting winding of the roving on to the former at a nearly constant temperature. 200 tex 4 800 tex 200 tex 4 800 tex 22 tex 220 tex 0,4 Pa s 40 % 300 mm 220 mm 70 % 70 % 52 % 0N 15 N 0 r/min 70 r/min 0,5 mm 5 mmI

If a different system is used,

38、 details shall be given in the test plate preparation report (clause 11). 8.3.2 Impregnating bath (see Figure 1) The temperature of the resin system in the bath shall be monitored to maintain its viscosity (see 5.2) as nearly constant as possible in order to ensure uniform and complete impregnation

39、of the roving. It is therefore recommended that the impregnating bath should have a double wall permitting the circulation of a temperature-regulating liquid, and that the dimensions of the bath allow an impregnation length of at least and provide a resin capacity of about . The type of bath shown i

40、n Figure 1 is given as an example. It is recommended that the bath have the following characteristics: an eye-type thread guide at the entrance to prevent abrasion (made of e.g. polytetrafluoroethylene or chromium- plated metal); a thread guide at the exit, ensuring complete impregnation without dry

41、ing; devices for retaining resin foam; guide rods under the resin surface (alternating sets of flat and grooved). 8.3.3 Impregnating roller (see Figure 2) The roller shall be corrosion- and wear-resistant. It shall be free-wheeling and have a minimum diameter of . The length of the area of contact b

42、etween the roving and the roller shall be not less than of the roller circumference, and the roller shall be immersed in the resin to a depth of approximately to of its diameter. A doctor blade shall be used to control the amount of resin on the roller. The distance between this blade and the roller

43、 shall be variable between and . The setting of this blade shall be determined by preliminary tests. A scraper blade shall be used to remove the resin the roving does not pick up.

If a press with heated platens is not available, the following may be used: a system for clamping the outer-mould pieces in place; an oven capable of maintaining the curi

Mount the former on the spindle of the winding machine. When the impregnating bath has to be kept at a temperature higher than , it is recommended

49、that the former be maintained at as nearly constant a temperature as possible (by means of a radiant panel for example). Adjust the speed of rotation of the spindle to obtain a roving speed of between and ; the speed shall be selected such that the winding operation can be completed during the pot life of the resin (see 5.2).
