چکیده
This research study demonstrates a carbon fiber reinforced polymer (CFRP) composite laminate with an embedded thermoelectric (TE) enabled glass (GF) ply. The TE-enabled GF functional ply was purposely laminated to create structural through-thickness generator (TEG). Simultaneously, the highly conductive (CF) reinforcing phase served as electrodes for device. Tellurium nanowires (NWs) were incorporated in various mass ratios PEDOT:PSS matrix produce different TE pastes. pastes deposited on fabrics via facile blade coating technique. highest power factor (57.2 ?W/m.K2, in-plane Seebeck coefficient +189 ?V/K) exhibited by formed paste specific ratio of 1:1 (Te NWs PEDOT:PSS). plies employed manufacturing both 10-ply unidirectional (UD), and cross-ply laminates.

Three-point bending tests indicated ca. 10% decrease flexural properties integration TEG functionality configuration.

Piezoresistivity (change of the volume electrical resistivity with strain) in continuous carbon fiber polymer-matrix structural composites allows electrical-resistance-based strain/ stress sensing. Uniaxial through-thickness compression is encountered in fastening. As shown for a 24-lamina quasi-isotropic epoxy-matrix composite, compression results in (i) strain-induced reversible decreases in ...
