Standard for testing glass fibres


The tensile strength of glass fiber is high, the elongation is small (3%), the standard of test methods are: Gb 1438-1993 synthetic staple Fiber crimp test method, GB/T 15232-1994 textile glass fiber felt tensile fracture strength determination, Gb 7689.5 glass fiber tensile breaking strength and breaking elongation determination, GB T152394 Textile glass fiber felt tensile fracture strength determination, GB/t 7689.5-2001 reinforcing material Methods of test for woven fabrics-part 5th: Determination of tensile breaking strength and elongation of glass fibres, etc. The test of tensile strength of single fiber is to adopt high-strength high modulus fiber strength meter which can test glass fiber.
