Foreword
This standard also replace the GB/T 3365-1982 "carbon fiber reinforced plastic void content test method (microscopy)" and GB/T 3366-
1996 "Test method for plastic fiber volume content of carbon fiber reinforced."
This standard and GB /3365-1982 and GB/T 3366-1996 compared to major changes in T as follows.
--- The GB/T 3365-1982 and GB/T 3366-1996 merged into one standard;
--- Increase Normative references (see Chapter 2);
--- Modifications void content test principle (GB/T 3365-1982 in Chapter 1, the standard 3.1);
--- Ultrasonic cleaning equipment is not required test (GB/T 3365-1982 in 3.1.4, 6.2.3 of this standard);
--- Increase test environment condition contents (see Chapter 7).
The standard proposed by China Building Materials Federation.
This standard by the national fiber-reinforced plastic Standardization Technical Committee.
This standard was drafted. Beijing glass Composite Material Co., Ltd., Beijing Institute of Aeronautical Materials.
The main drafters. Zhang Haiyan, alluvial gold Wei, Wang Xuan, Nie Lei, Chen Xinwen.
This standard replaces the standards previously issued as follows.
--- GB 3365-1982;
--- GB 3366-1982, GB/T 3366-1996.
Carbon fiber reinforced plastics void content and fiber volume fraction
experiment method
1 Scope
This standard specifies the principle of a carbon fiber reinforced plastics void content and fiber volume content of test materials, test equipment, samples, test
Test conditions, test procedures, calculations, test results and test reports.
This standard applies to the determination of unidirectional and multidirectional carbon fiber orthogonal plies reinforced plastic void content, fiber volume fraction. Aramid and glass
Glass fiber reinforced plastic can also refer to use, but not for the determination of fiber volume fraction fabric reinforced plastics.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 1446 Test methods for fiber reinforced plastic properties General
Principle 3
3.1 void content test principle
Carbon fiber reinforced plastic, with an optical microscope, image analyzer or graph paper transparent measured total pore surface over the entire cross section of the sample
Product and cross-sectional area of \u200b\u200bthe sample percentage is void content of the sample.
3.2 fiber volume content of the test principle
Carbon fiber reinforced plastic, or by an optical microscope image analyzer measurement of fiber surface area occupied by the observation area and observation hundred
Division ratio, that is, the fiber volume content of the sample.
4 test material
4.1 embedding material.
4.2 mill sandpaper, choose No. 320, No. 400, No. 600, No. 800.
4.3 polishing fabric, the choice of velvet, woolen.
4.4 polishing paste, use W0.5 W1 or synthetic diamond polishing paste.
4.5 photographic equipment.
4.6 counting grid transparent film.
5 Test Equipment
5.1 void content test equipment
5.1.1 reflection microscope with an eyepiece grid, micrometer and other accessories.
5.1.2 image analyzer.
5.1.3 grinding, polishing equipment.
5.2 fiber volume content of the test equipment
5.2.1 image analysis, quantitative measurement with analysis software (particle size, the percentage of the area) and a data processing system.
5.2.2 microscope can be enlarged to more than 1200 times.
