| Summary: | The burgeoning reliance on electronic devices in sectors such as aerospace systems and consumer electronics necessitates
robust electromagnetic interference (EMI) shielding. Current challenges often involve balancing material performance with sustainability
and cost-effectiveness. This study addresses these needs by exploring the use of recycled carbon fiber (rCF) in acrylonitrile butadiene
styrene (ABS) composites for enhanced EMI shielding, contributing to more sustainable material development. We investigated the impact of different rCF treatments (untreated, chemically treated, and chemically-mechanically treated) on mechanical properties (tensile
strength, stiffness, flexibility) and EMI shielding effectiveness of these composites. Furthermore, the role of electron beam (EB) irradiation at 200 kGy in creating cross-linked structures to boost conductivity and shielding performance was thoroughly examined. Fabricated
via melt compounding, the composites’ electrical conductivity, and EMI shielding capabilities were the main focus. Results show that
the EB-irradiated composite with 30 wt% chemically treated rCF achieved a peak electrical conductivity of 1.34 × 10−8
S/m and an
impressive shielding effectiveness of 46.13 dB. These findings offer crucial insights for developing high-performance, cost-efficient, and
potentially sustainable rCF-filled ABS composites for advanced EMI shielding applications. |
