ASTM WK30557

    Work Item: ASTM WK30557 - New Specification for Standard Specification for Laser Sintering High Melt Temperature Polymers for Non-Structural Aerospace Components

    (What is a Work Item?)

    Developed by Subcommittee: F42.05 | Committee F42 | Contact Staff Manager



    1. Scope

    1.1 This specification covers laser sintered components using a high melt temperature polymer e.g. polyetheretherketone (PEEK), polyaryletherketone (PAEK), polyetherketoneketone (PEKK), etc. that has been optionally modified to dissipate a static charge. The components produced by this process are used typically in non-structural aerospace applications such as clips, brackets and air ducts. Components manufactured to this specification are often, but not necessarily, electrically bonded to a structural ground. 1.2 This specification is intended for use of purchasers and /or producers of moderately conductive, high temperature laser sintered components for defining the requirements and assuring component properties.

    There is a need for high melt temperature polymers that can optionally dissipate static charges for the aerospace industry. This specification can be used for new air systems as well as DoD repair facilities. The material and process in this work item represent ongoing research funded by a critical phase II SBIR. The goal is to have an ASTM standard developed simultaneously with the technoglogy to support manufacturing readiness level.
