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

Polymer 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 ...

Curved-Line Cutting Using a Flexible Circular Saw

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
We propose a flexible circular saw for high-speed cutting of curved lines in carbon fiber-reinforced plastic (CFRP). A conventional circular saw is appropriate for straight line cutting, but it cannot be applied to curved line cutting because of the ...
