Preparation of nanocarbon-coated glass fibre/phenolic composites for EMI shielding

Fibre-reinforced composites are significant materials for the construction of high-end aircraft; however, their complex manufactural process and high cost hinder their large-scale applications. Herein, a newly phenolic-based composite reinforced by nanocarbon-coated glass fibre (NCGF) prepared by pyrolysis of polyethylene was proposed to meet this challenge. The results show that the tensile strength and electrical conductivity of the composites increase withthe increase of NCGF content, approaching 40.06 MPa and 1.63 ${\times}$ 10$^{–6}$ S cm$^{–1}$ with the NCGF usage of 20 wt%. The electromagnetic shielding effectiveness (EMI SE) of the as-prepared composite is up to 21.82 dB at 20 wt% X-band(8.2–12.4 GHz). The relationship between total EMI SE (SE$_T$), surface reflection (SE$_R$) and absorption of electromagnetic wave (SE$_A$) of the as-prepared composite is systematically analysed. It is found that SE$_A$ is the main factor for EMI shielding. In addition, the increase of the imaginary part of the permittivity and the dielectric loss of the composite can also make the composite obtain a better electromagnetic shielding effect. In summary, our work introduced a facile paradigm for the production of low-cost fibre-reinforced composites as EMI shielding materials.
