Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

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.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.
