Abstract
There is an increasing demand for battery pack housing materials that offer lightweight, mechanical, and thermal insulation properties to prevent thermal runaway caused by external mechanical and/or thermal stimuli. In this study, by applying a polypropylene (PP) chain-length control strategy to impregnate micropores between carbon fibers (CFs) and to maintain nanopores within the incorporated silica aerogel (SA), a CF reinforced thermoplastic (CFRTP) with superior thermal insulation properties was proposed. The PP chain length, used as matrix, was identified as the most important structural factor determining the extent of CF impregnation and preservation of the SA nanopore structure. Additionally, the optimized CFRTP, in which SA nanopores were preserved and CF was well-impregnated, exhibited excellent thermal insulation with a value of 0.045 W/m·K. The excellent thermal insulation properties of the proposed CFRTP make it a promising candidate for applications in electric vehicle battery pack enclosures.
期刊介绍:
The Journal of Materials Research and Technology is a publication of ABM - Brazilian Metallurgical, Materials and Mining Association - and publishes four issues per year also with a free version online (www.jmrt.com.br). The journal provides an international medium for the publication of theoretical and experimental studies related to Metallurgy, Materials and Minerals research and technology. Appropriate submissions to the Journal of Materials Research and Technology should include scientific and/or engineering factors which affect processes and products in the Metallurgy, Materials and Mining areas.
