The study is focused on multifunctional performance of carbon nanotubes (CNT) and Graphene nanoplatelets (GNP) reinforced PEEK composites enabled via fused filament fabrication (FFF) additive manufacturing (AM) utilizing in-house nanoengineered filaments. Thermo-physical, mechanical wear characteristics electro-conductive nanocomposites are reported. coefficient thermal expansion (CTE) found to decrease by 26% 18% with the incorporation 5 wt% GNP 3 CNT into polymer, respectively. in CTE...
We report the energy absorption and piezoresistive self-sensing performance of 3D printed discontinuous carbon fiber (CF)-reinforced polyetheretherketone (PEEK) cellular composites. Experiments conducted on three different 2D lattices with hexagonal, chiral re-entrant topologies same relative density (33%) CF loading (30 wt%) reveal that CF/PEEK hexagonal lattice (HL), due its relatively brittle response, shows about 40% 9% decrease in specific (SEA) under in-plane out-of-plane compression,...
This study explores the potential of engineered interphases to enhance performance fiber-reinforced composites through an integrated approach combining theory, computation, and experiments. A theoretical axisymmetric modeling framework is introduced evaluate stress distribution within a three-phase composite system subjected axial pull-out loads. The comprises cylindrical fiber embedded in matrix with intermediate interphase whose modulus varies radially, following linear power-law gradation...
