ASTM WK37485

    Work Item: ASTM WK37485 - Revision of D3532 - 99(2009) Standard Test Method for Gel Time of Carbon Fiber-Epoxy Prepreg

    Developed by Subcommittee: D30.03 | Committee D30 | Contact Staff Manager

    1. Rationale

    The accuracy of the hotplate stated in section 4.2 is unreasonable due to known instrument error. The procedure described in section 8.6 to determine gel time is unclear, and the stringing phenomenon does not occur in all prepreg systems.
