Reliability evaluation of the performance of non-woven carbon fiber fabric for heating element applications

In this study, the wet method was used to manufacture the short-carbon fibers (CFs) and polyethylene-based non-woven fabric for joule heating applications. The heating perfor-mance of the fabric was investigated according to the combination ratio of short CFs and polyethylene fibers (PFs). The effect of operating conditions such as the periodic switch-on and switch-off of the applied voltage, the voltage applied continuously for a long-time, and multiple mechanical bending-release cycles applied to the sample were studied. The non-woven fabric with an equal amount (in weight) of CFs and PFs was found to have the best performance. The non-woven fabric provided fast heating and fast cooling with an average temperature of about 55 degrees C which was attained in just 9 s for the applied voltage of 3 V. This indicated that lower power was required to achieve good temperature for heating appli-cations with the developed non-woven fabric. (C) 2021 The Authors. Published by Elsevier B.V.

Automated summary

In this study, short carbon fibers (CFs) and polyethylene-based non-woven fabric were manufactured using the wet method for joule heating applications. The heating performance of the fabric was investigated based on different ratios of CFs and polyethylene fibers (PFs), with the best performance found in fabric with equal amounts of both. The fabric demonstrated fast heating and cooling, reaching an average temperature of about 55 degrees Celsius in only 9 seconds with an applied voltage of 3 V, indicating lower power requirement for effective heating applications.
