Abstract
A novel self-heating 3D printed continuous carbon fiber (CCF)/epoxy (EP) mesh for deicing was proposed. Because of electron migrating conduction and hopping conduction, the conductivity of CCF reached 131.3 S cm−1 at 25 °C and increased by 1.1%–148.4 S cm−1 at 200 °C, exhibiting a negative temperature coefficient (NTC) effect. Because of the electron conduction of CCF and uneven thermal expansion of the fiber/matrix components, the CCF/EP mesh had NTC and positive temperature coefficient (PTC) effects. After specific hot-cold cycles, the resistance stability of the printed mesh was confirmed. Compared to unprotected glass fiber-reinforced composite laminate, the CCF/EP mesh reinforcement decreased the deicing time by 85% and had a protective effect on the residual flexural strength and modulus, fiber-resin bonding, and internal voids. Excellent conductivity, resistance stability, and electric self-heating performance indicate that 3D printed CCF/EP mesh is a promising candidate for use in deicing.
