Özet
Cementitious composites generally lack electrical conductivity, which limits their use in multifunctional applications such as self-heating systems. This study investigates the self-heating performance of concrete reinforced with continuous carbon fiber bundles, with emphasis on the effects of fiber configuration and placement density. Four continuous carbon fiber bundles were embedded into concrete specimens in straight, twisted, and braided configurations, combined with low (L), medium (M), and high (H) placement densities. Self-heating behavior was evaluated under applied AC voltages of 30 V and 45 V by monitoring surface temperature evolution using infrared thermography and recording electrical power consumption. The results showed that both fiber configuration and placement density significantly influence electrical network continuity and Joule heating performance. In particular, braided–high and twisted–high configurations exhibited the most efficient and stable self-heating behavior at both voltage levels, whereas low and medium density arrangements resulted in limited temperature increase. The findings demonstrate that the use of densely arranged continuous carbon fiber bundles, especially in braided configurations, provides an effective approach for developing self-heating cementitious composites suitable for infrastructure and building applications.
