Description
Summary:Carbon fiber-based composites (CFCs) have garnered widespread attention due to their exceptional mechanical properties and have been widely used in various fields such as aerospace, transportation, and military industries. However, little research has been conducted on the underlying mechanisms and factors affecting the photo/ electrical conversion of CFCs. In this study, a carbon fiber reinforced polyamide 12 (CF/PA12) composite was fabricated via selective laser sintering. The results showed that the CF/PA12 composite exhibited excellent photo-thermal conversion and Joule heating characteristics with the optimal mass fraction (15 wt%) of carbon fiber. The temperature of the CF/PA12 composite increased gradually with increasing solar intensity and reached its highest value when the CF/ PA12 was oriented parallel to the light direction. This study also demonstrated the selective regulation of CF/PA12 fiber orientation on material resistance and thermal resistance. A voltage continuously adjustable mode that integrates photothermal conversion was designed and verified through recyclable tests. The findings of this study expand the applications of carbon fiber reinforced polymer composites in temperature regulation and operation control.
