| Abstract [eng] |
Two types of modified glass fiber reinforced plastic (GFRP) were studied: with epoxy matrix modified by multiwall carbon nanotubes (MWCNT); with built-in interleave based on conductive nanofillers such as MXene and MWCNT. Structural approach was approbated for electrical conductivity prediction of MWCNT modified GFRP plate. The numerical analysis on electrical conductivity for modified composite plates with various fiber orientation angles showed a good agreement with experimental results. The investigation of the damaged composite plate was carried out by measuring the distribution of electrical potential in the bulk of the material for both GFRP with MWCNT modified matrix and impregnated interleave with MXene coating. The voltage distribution measured throughout the laminate allowed detecting the damage in its volume. Implementation of the conductive interleave in GFRP showed good potential to determinate the location, quantification, and geometry of the damage in the lamina. |
