1 Scope

This part of GB/T 27797 specifies a method of preparing a fiber-reinforced plastic sheet by a winding method using a glass fiber roving and

Thermosetting resin as raw material (excluding pre-impregnated fibers).

This section specifies the preparation of unidirectional reinforcing plates under optimal industrial conditions, which can be cut on these test panels for testing various mechanical properties

Can sample.

This part of GB/T 27797 is mainly applicable to glass fiber reinforced plastics made of polyester resin or epoxy resin, but can also be expanded

To other types of resins and reinforcing materials.

This part of GB/T 27797 is used in conjunction with GB/T 27797.1.

Note. For ease of understanding of this method, the term "roving" is used throughout the text and includes yarn unless otherwise specified.

See ISO 1268-1.

4 principle

A roving (or number of roving beams) is impregnated with resin, wrapped in several layers. Install the outer template on the mandrel to obtain the test plate

Find the final thickness. The curing may be carried out in a press with a heating plate or in an oven.

The method can simultaneously prepare two identical test boards.
