Development of chopped (non‐woven) carbon fiber reinforced composite sheet and its electrothermal performance for heating applications

Abstract

Non‐woven carbon fiber sheet‐based heaters have been used for various thermal and material science applications, which possess rapid thermal heating at low input power. This work investigates the optimization of chopped carbon fiber composite sheet for heating applications. Here, different lengths of chopped carbon fiber have been used to fabricate the composite sheet. The parameters of composite sheets, such as morphology, porosity, electrical conductivity, mechanical property, and thermal stability, were studied. Besides, the electrothermal performance of prepared sheet heaters was investigated, and the results were compared at the input voltages of 10 and 12 V. The input power consumed by different sheet heaters was also investigated. The optimal chopped size of the carbon fiber composite sheet showed the highest surface thermal heating temperature of 245°C at 12 V.

Highly Sensitive and Stable Flexible Smart Sensors Based on Commercial Carbon Fiber Powder Inks

“…Therefore, the development of a wearable flexible sensor by a low-cost, simple-to-manufacture, and equipment-independent way has become an urgent demand. Carbon fibers as one familiar material exhibits a series of unique physical and chemical properties, such as low cost, ultrahigh strength, − good conductivity, , thermal conductivity, , and super chemical stability. , In addition, carbon fibers have recently been reported with the good photothermal conversion ability, which will broaden its applied fields. In combination with the commercially available property, the carbon fiber is a potential candidate used for conducting flexible wearable electronic devices and suitable for the extensive modern manufacturing and high-tech industries.…”
