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.

3 healthy and safe

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.

5 material

5.1 roving This method is suitable for all yarns with a linear density of.200 to 4800tex. The yarns with lower linear density can be combined to make their threads The density is.200 to 4800tex (for example, 10 bundles 22tex is 220tex). 5.2 resin system The recommended resin system (polyester or epoxy curing system) should meet the following properties. ......
