| Abstract Scope |
Polymeric resins with fiberglass are thermosetting composite materials, valued for their properties such as good mechanical strength and suitability for structural applications. This study characterizes a composite of polymeric resin with fiberglass reinforced with polycarbonate (PC) microfibers, produced by solution blow spinning (SBS), to enhance functional scale models of tugboats for the University Nautical Design Challenge (DUNA) an international competition held annually in Joinville, Brazil. The SBS technique uses compressed air and an injector nozzle with concentric needles to generate nanofibers from a PC polymer solution. The incorporated microfibers were analyzed along with the composite by Thermogravimetric Analysis (TGA), FT-IR spectroscopy, UV aging, humidity, scanning electron microscopy (SEM), and mechanical strength tests. The results showed a composite with improved mechanical strengths due to the PC microfibers, although humidity and UV exposure can still degrade the materials over time. |
