A Sustainable Strategy for Enhancing Recycled CFRP via Electro‐Spun Low‐Melting Temperature Polyamide Nanofiber Interlayers

Polymer Composites, EarlyView.
Low‐melting temperature polyamide nanofiber veils bond and bridge the interface of recycled CFRP via epoxy ring‐opening reaction, restoring its mechanical performance. ABSTRACT The increasing demand for lightweight materials with high specific strength has led to rapid growth in the use of carbon fiber reinforced plastics (CFRPs), accompanied by a ...

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

Polymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

Effect of Temperature on Tensile Properties of Electrospun Nanofibre Interleaved Carbon Composites

Polymer Composites, EarlyView.
Thermal Durability of Electrospun Nanofibre Interleaved Composites. ABSTRACT Carbon fiber composites are susceptible to brittle damage modes such as matrix cracking and delamination. The inception and propagation of these invisible damages are responsible for loss in load‐bearing capacity and accelerating environmental degradation.
