ASTM WK67852

    New Test Method for Characterizing Tack of Prepregs

    (What is a Work Item?)

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



    WK67852

    1. Scope

    - Provide a peel type test method to quantitatively measure the tack of prepregs - Simple test fixture compatible with standard test frame and environmental chamber is proposed


    Keywords

    - Prepreg:- Tack:- Peel:- Automated Material Placement

    Rationale

    - No reliable test method exists for prepreg tack; existing methods focus on adhesive materials (reviewed ASTM D2979, D6195, D3121 and D1781) - Proposed peel type test also takes into account resin rheology - Simple test fixture compatible with standard test frame and environmental chamber is proposed - Tests designed primarily for automated material placement of prepregs; can be used to understand the prepreg material

    The title and scope are in draft form and are under development within this ASTM Committee.
