Standard Test Method for Gel Time of Carbon Fiber-Epoxy Prepreg

Importancia y uso:

4.1 This test method can be used to obtain the gel time of resin squeezed from prepreg tape or sheet material. This test is a useful measure for material acceptance.

4.2 The gel time will vary with the test temperature. The temperatures specified in this test method are two of many temperatures often used in processing epoxy prepreg material. If other test temperatures are used, this is to be clearly noted as indicated in 10.1.2.

4.3 Gel time is not recommended as a measure of out time (unacceptable degree of cross-linking). Use Resin Flow Test Method D3531/D3531M, Dynamic Viscosity Test Method D4473, or Dynamic Mechanical Procedures Test Method D7750.
