1 Scope

This section GB/T 27797 specifies the use of heat and pressure and a different device (such as a pressing machine, pneumatic, hydraulic and vacuum bagging machine Equipment) forming a multilayer unidirectional fiber prepreg or fabric (prepreg) test panel method is applicable to all reinforcements and resins. This method is applicable to a thermosetting resin prepreg and the thermoplastic resin prepreg, the prepreg according to the requirements of the order and the time to prepare a test plate Laying direction, compacted and cured under heat and pressure/vacuum, the test plate prepared suitably machined into test specimens. Standard board made by this method can be used to analyze its composition, i.e., reinforcing material, resin additives and the like, can also be used to identify the final product Comprehensive quality.
