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.

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]

, 2007
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Investigation of a Polyamide 6 (PA6) and Polybutylene Succinate (PBS) Blend as Candidate Matrix for Self‐Healing Application

Polymer Engineering &Science, EarlyView.
This illustration shows polyamide 6 (PA6) blended with 20–50% polybutylene succinate (PBS) by volume. The balance between tensile properties, fracture toughness and self‐healing capability is achieved in the 30% vol PBS blend. Thermal healing at 140°C results in 40% fracture toughness recovery in a blend containing 30% vol PBS.
