Experimental and Numerical Investigation of the Mechanical Properties of Compression‐Molded Alkali‐Treated Sisal/False Banana Fiber‐Reinforced Polymer Composites

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
Alkali‐treated hybrid sisal/false banana fiber‐reinforced polyester composites were fabricated by compression molding and evaluated experimentally and numerically. The 5 wt.% NaOH treatment improved fiber–matrix adhesion, enhancing tensile, flexural, and impact properties.

Evaluation of Interface Shear Strength of Natural Kenaf Geogrid and Recycled Concrete Aggregate for Sustainable Pavement Applications

open access: yesJournal of Natural Fibers, 2022
In this research, a natural kenaf geogrid was used to reinforce recycled concrete aggregate (RCA) as a base/subbase material. The interface shear behavior of kenaf geogrid-reinforced RCA was investigated using a large-scale direct shear test (LSDT).

Enhancing Mechanical and Physical Properties of Jute/JUCO/Glass Fiber Hybrid Composites Through TiO2 and CuO Microparticle Reinforcement

open access: yesSPE Polymers, Volume 7, Issue 3, July 2026.
Symmetrical Jute/JUCO/Glass hybrid epoxy composites were reinforced with TiO2 and CuO microparticles. Incorporating 3 wt.% CuO increased tensile strength by up to 63.7%, while 3 wt.% TiO2 maximized flexural and impact properties alongside superior moisture resistance, demonstrating that these fillers significantly enhance natural fiber biocomposites ...

Production Gaps Among Farmers With Disabilities Are Associated With Limited Technology

open access: yesAgricultural Economics, Volume 57, Issue 4, July 2026.
ABSTRACT In sub‐Saharan Africa, agriculture is vital; however, the systematic exclusion of persons with disabilities from farming hinders sustainable development and social equity. Although several studies have analyzed productivity differentials across various dimensions of social exclusion, empirical evidence on technology access, farming efficiency,
