1 Scope

This section GB/T 27797 specifies the method reinforced thermoplastic sheet (GMT/STC) molding prepared test panels. Prepared

Test panels for measuring a sample processing laminates mechanical and physical properties. This method is applicable to thermoplastic resin matrix, glass fiber,

Carbon fiber, aramid fiber or other reinforcing material (reinforcing materials may be used alone or in combination, the form should be suitable for molding) by molding

Molded laminates.

GB/T 27797 and this part of GB/T 27797.1 used together.
