Thermal aging properties and electric heating behaviors of carbon fiber paper-based electric heating wood floors

Abstract

Carbon fiber (CF) paper is an excellent material for use in electric heating wood floors systems. In this paper, a CF paper-based electric heating wood floor was prepared using a hot pressure process. The thermal aging properties and electric heating behaviors of the CF paper-based wood floors were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and a temperature recorder. The CF paper exhibited excellent thermal stability, and its structure and morphology did not show any changes after exposure to 110 °C for 15 h. The surface temperature of the CF paper increased as input voltage increased. The positioning of CF paper in the middle of wood floors was believed to be the optimum design for electric heating wood floors. Theoretical calculations showed that the CF paper based electric heating wood floors (1.1 m2) could increase room (3 m × 4 m × 2.6 m) temperature by 12.9 °C.

Preparation and electrothermal properties of graphene electrothermal composite floor

“…𝑦 = 0.98 + 0.132𝑥 , (𝑅 2 = 0.9979) (4) As shown in Table 2, as the input power density increased, the temperature variation of the plate surface increased and the heating time decreased. According to the law of conservation of energy (Li 2018), the heat generated by the graphene heating film is equal to the sum of the heat stored in the graphene electric heating floor itself and the heat transferred to the environment (Song et al 2017;. The heat generated by the graphene heating film could be calculated as follows (Eq.…”
