| Abstract Scope |
Additively manufactured (AM) silicone materials can be tailored to meet various performance requirements in many ways, including introduction of conductive fillers and/or friction reducing coatings. Understanding their aging, compatibility behavior and outgassed compounds of the modified formulations is vital to predict long-term material behavior. We aged AM-silicone compositions under compression at various temperatures and measured their compression set and load retention properties to develop time temperature superposition (TTS) curves used to estimate long-term performance. We also performed thermal aging for 12-weeks and periodically evaluated the headspace gas constituents to quantify residual volatile compounds, degradation products, and screened for potential incompatibilities. Here we present our latest data for mechanical testing and headspace gas analysis for different AM-silicone compositions.
