| Abstract Scope |
Thermoplastic additively manufactured materials are being explored as a potential for adhesively bonded repair for carbon epoxy composites. The targeted applications are difficult repairs with very low loading requirements. If successful, this could reduce rework and allow for a subset of complex composite repairs to be executed by less skilled artisans at lower-level maintenance facilities. These repairs would take advantage of fielded additive manufacturing systems across the fleet, expanding the application space for this distributed manufacturing capability. Proof of concept data has shown the potential to bond additively manufactured Ultem 9085, a polyetherimide thermoplastic, to epoxy thermoset composites using EA9394.
To evaluate the suitability of materials, fracture toughness and double lap shear data has been generated. Additive material was characterized by varying the infill pattern using standard infill or raster settings and by mimicking quasi-composite lay-up schemes. Additive material build orientation was also varied for each infill pattern. The impact of build orientation and additive infill pattern on mechanical properties will inform the envelope of suitability for repair applications as well as repair design. Mechanical test results are presented. |
