Abstract Scope |
Microwave irradiation enables thermal curing of composite thermoset materials not possible in light-based additive manufacturing approaches. Herein we show our group's progress in controlling localized curing in transparent and opaque composite thermoset materials via directed microwave irradiation. This exploratory study focused on controlling cure spot size in relation to power, thermal heat profile, and time in a wide range of materials. Numerical simulations studying microwave energy localization are conducted to determine key parameters for experiments. The experimental system comprising a microwave applicator coupled to an RF amplifier will be discussed. Additives include glass, ceramic, and conductive nanoparticles, as well as fiber reinforcement. This work culminated in a prototype additive manufacturing system, capable of making large opaque structures. |
