Recycled Polyacrylonitrile Nanofiber Interleaves With Graphene Nanoplatelets for Adhesively Bonded Composite Joints: Lap‐Shear and Opening‐Mode Fracture Performance

open access: yesPolymer Composites, EarlyView.
Textile‐waste Orlon is transformed into recycled PAN nanofiber interleaves for tougher and more damage‐resistant adhesive bondlines. ABSTRACT This study presents a sustainable toughening strategy for adhesively bonded CFRP joints by using electrospun polyacrylonitrile (PAN) nanofiber interleaves produced from virgin PAN (vPAN) and recycled PAN (rPAN ...

Influence of Thermal Cycling on Friction, Wear, and Damage Evolution of Fused Deposition Modeling of 3D‐Printed Glass Fiber Reinforced Polylactic Acid Composites

open access: yesPolymer Composites, EarlyView.
Schematic illustration of the experimental procedure of the specimens. ABSTRACT This research work investigated the effect of the cyclic thermo‐hygrometric aging regime between −20°C and +40°C with 0–400 cycles on the reciprocating tribological properties of fused deposition modeling (FDM) printed polylactic acid (PLA) and the same material reinforced ...
