Kinetics of Elastic Recoil in the Wings of the cicada, Dundubia rufivena

Natural Sciences, Volume 6, Issue 2, April 2026.
We quantify elastic recoil in cicada wings using high‐speed videography, revealing faster bending than torsional recoil. Wing stiffness increases when attached to the thorax, demonstrating a body‐wing spring system and highlighting that elastic recoil must be understood through whole‐organism mechanics rather than isolated wing properties.

Mechanical and Microstructural Characterization of Hybrid Palm Fiber–Carbon Fiber Composites

SPE Polymers, Volume 7, Issue 2, April 2026.
ABSTRACT Hybrid fiber‐reinforced polymer composites combining natural and synthetic reinforcements offer a promising route toward lightweight and sustainable structural materials. In this study, carbon fiber–palm tree fiber reinforced epoxy hybrid composites were fabricated using a hand lay‐up technique with a symmetric sandwich‐type stacking sequence,

Toward Greener Hybrid Composites: Effect of Wood Powder and Calcium Carbonate on Recycled HDPE With Tyre and MAPE Modifiers

SPE Polymers, Volume 7, Issue 2, April 2026.
Recycled high‐density polyethylene (rHDPE) was reinforced with wood powder (0–25 wt%) and calcium carbonate (5 wt%), modified with ground tyre powder (5 wt%) and maleic anhydride grafted polypropylene (MAPP, 5 wt%). The hybrid filler system demonstrated: Mechanical Enhancement: Tensile strength increased by 25.5%, stiffness by 45%, and tensile modulus ...
