The work of preparing International Standards is normally carried out
11、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, also take part in the work. ISO coll
12、aborates 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 2. The main task of technical committees is to prepare International St
13、andards. 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 elements
14、of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3597-4 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This second edition cancels and replaces
15、 the first edition (ISO 3597-4:1993), which has been technically revised. ISO 3597 consists of the following parts, under the general title Textile-glass-reinforced plastics Determination of mechanical properties on rods made of roving-reinforced resin: Part 1: General considerations and preparation

17、mechanical properties on rods made of roving-reinforced resin Part 4: Determination of apparent interlaminar shear strength 1 Scope This part of ISO 3597 specifies a method for determining the apparent interlaminar shear strength of composite rods of circular cross-section made of roving-reinforced
18、resin. The test may be carried out on “as-moulded” rods, or on rods that have been pretreated by immersion in boiling water (or another medium) for a specified time. The test is intended for inspection and quality control of rovings or for evaluating their suitability for use in a resin system. The
19、results obtained are not intended for the generation of design data. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced do

A load applicator suitable for a 6-mm-diameter test specimen is show
22、n in Figure 1. It is important that the radius R of the waist is not more than 0,25 mm larger than the actual (measured) radius of the test specimen. 3.1.2 The span between the supports shall be 5 times the diameter of the test specimen. 3.2 Micrometer or vernier gauge, capable of measuring to the n
23、earest 0,1 mm. 4 Preparation and conditioning of test specimens Prepare and condition a given number of specimens in accordance with the method given in ISO 3597-1. For each type of test (“as-moulded” or pretreated), the minimum required number of specimens is eight. If specific statistical limits a
24、re agreed between interested parties, additional specimens may be tested to permit statistical analysis of the results. The required specimen length is 8 times its diameter, i.e. 48 mm for a rod of diameter 6 mm. BSISO35974:20031ISO 3597-4:2003(E) 2 I SO 3002 All irhgts seredevrDimensions in millime
25、tres NOTE When specimens with a different diameter are tested, a load applicator of different dimensions needs to be used. Figure 1 Example of load applicator for testing specimens of diameter 6 mm 5 Procedure 5.1 Before carrying out the interlaminar-shear test, measure the diameter of each test spe
26、cimen with a micrometer or vernier gauge (3.2) to the nearest 0,1 mm at two points around the circumference located 90 apart at the centre of the specimen. Use the average of these two measurements in the calculation of the results. 5.2 Carry out the interlaminar-shear test on the specimens in accor
27、dance with ISO 14125, modified as specified in 3.1, in the same standard laboratory atmosphere as that used for specimen conditioning. The speed of the load applicator shall be 1 mm/min. Continue the test until the specimen fails. Record the maximum force, in newtons, that occurred during the test.
28、The person requiring the test may require that the mode of failure be recorded (see Figure 2). a) Type X (delamination) b) Type Y (splitting) c) Type Z (flexural deformation) aTop view. Figure 2 Acceptable and unacceptable failure modes (Only Type X is acceptable) 5.3 Check that a type X failure mod
29、e is obtained with each specimen. For other failure modes, repeat the test on further specimens. Continue testing until at least five valid results are obtained (see Clause 4). If five valid results are not obtained, prepare and test a further set of specimens. If this second set results in similar
30、difficulties, record this situation in the test report. BSISO35974:20032ISO 3597-4:2003(E) I SO 3002 All irhgts seredevr 36 Expression of results For each test specimen, calculate the apparent interlaminar-shear strength , expressed in megapascals, using the equation: 2 8 F d = 3where F is the break
31、ing force, in newtons; d is the diameter, in millimetres, of the test specimen. 7 Precision The precision of this test method is not known because inter-laboratory data are not available. When inter-laboratory data are obtained, a precision statement will be added at the following revision. 8 Test r
32、eport The test report shall include the following information: a) a reference to this part of ISO 3597; b) all information necessary for complete identification of the roving tested; c) all information necessary for complete identification of the resin used; d) the diameter of the mould used to prep
33、are the test rods; e) whether a release agent was used and, if so, details of the agent used; f) the curing and post-curing conditions; g) the test atmosphere; h) the test results: 1) for “as-moulded” specimens, the glass content, diameter, apparent interlaminar-shear strength and, if required, mode
34、 of failure of each specimen tested and (except for the mode of failure) the average value; 2) if testing was also carried out after pretreatment: the medium used; the length of the pretreatment; the individual and average values of the flexural strength after pretreatment.
