Strength Properties of Surface Modified Kenyan Sisal Fibres
Journal of Natural Fibers, 2022 This study aimed at determining and comparing the mechanical properties of natural, mercerized, and cornified sisal fibers. Sisal fiber morphology was modified by mercerization using a 0.06 Molar sodium hydroxide solution and by a seven-hour, seven cycle

Exploration of Mechanical Properties of Enset–Sisal Hybrid Polymer Composite
Fibers, 2022 Enset and sisal fibers are among the most widely used reinforcement to fabricate natural fiber-based composite materials. Hand lay-up techniques were employed in this study to fabricate enset–sisal (E/S) hybrid fiber composite with volume ratios of 100/0,
