GB/T 32788.2-2016

This standard specifies a test method for measuring the resin flow of prepreg materials, which are fiber reinforcements pre-impregnated with a resin system. It is applied in the manufacturing and quality control of composite materials, particularly in industries such as aerospace, automotive, and wind energy, where consistent resin content and flow behavior are critical for laminate properties. The test ensures that prepregs meet processing requirements for curing and lay-up procedures.
