Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.

Effect of Veil Interlayer Type and Placement on the Mechanical Response of Carbon and Glass Fiber/Epoxy Composites

Polymer Composites, EarlyView.
Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored

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 ...
