Test method for properties of prepreg—Part 5: Determination of resin content

This standard specifies various methods for determining the resin content of prepregs, including extraction, dissolution, and combustion methods. These methods primarily involve the use of analytical balances and other instruments to calculate the resin mass percentage through separation and weighing. Among these, the combustion method is applicable only to glass fiber-reinforced materials. Additionally, advanced non-destructive testing techniques such as near-infrared spectroscopy and low-field nuclear magnetic resonance have been studied and applied in this field.
