Abstract Scope |
Numerous industries use thermoplastics to meet the demanding requirements of high-temperature and high-pressure sealing applications. Flat backup rings, common components of sealing assemblies, can be additively manufactured using fused filament fabrication and can perform comparably to their conventionally manufactured counterparts. The load response which develops within the seals is largely driven by pressure and the geometry of the extrusion gap which is located opposite of the primary seal in the assembly. To better address this loading condition, flat backup rings were fabricated with conventional print patterns and compared to custom radial print patterns which were configured with planar and non-planar layer configurations. Specimens underwent pressure vessel tests to provide an estimate of seal performance at high-pressure and high-temperature. The observed relationship between test results and print orientation may inform tuning of sealing structures in numerous industries to further optimize seals for multiple objectives. |
