Abstract The variations in electrical resistance of carbon fiber composites under different damage modes are critical for the design electrically conductive components. Here, we developed a random contact model to analyze changes subjected various scenarios. An ideal rectangular grid was constructed matrix form utilizing nodal voltage and current method. each branch calculated based on normal distribution orientation angles. To simulate branches among points within resistor network, were...
The effect of thermo-oxidative aging on mechanical properties is important to designing carbon fiber-reinforced composites serviced in long-term atmospheric environments. Here, we report the progressive bending damage behaviors fiber/epoxy 3D angle-interlock woven (3DAWCs) after aging. Three-point tests were conducted characterize different days. electrical resistance change 3DAWCs was also simultaneously measured with two-probe method during three-point tests. Combining side image and...
Abstract Investigating the macro‐mechanical properties of polymer composites at nanoscale is a challenging topic. Here we report compressive performances carbon fiber‐reinforced epoxy using molecular dynamics (MD) simulations. The evolution microstructure and microscopic energy, including free volume, radius gyration, dihedral angle, potential interaction has been investigated to characterize behaviors nanoscale. Molecular chains gradually bend, movement space decreases during compression...
