This study investigates the effects of fiber treatments on mechanical properties pineapple leaf reinforced polyester composites (PALF/PE). The Fiber were conducted with 3%, 6% and 9% NaOH for 2 hours. untreated treated PALF/PE fabricated by vacuum infusion method. result analysis revealed that indicated an increasing pattern in compared to composites. highest tensile strength was112 Mpa at 6 % ...

The use of natural fibers as reinforcement for composite materials is on the rise due to need reduce environmental damage and manufacture sustainable products. One used this purpose fique fiber. This article describes a student chair with fiber-reinforced material. To choose amount be in elaboration chair, mechanical characterization several composites different percentages fiber was carried ou...

This study aims to observe the impact of fiber lengths and NaOH treatment on tensile properties composite materials made from borassus polyester matrix. used fibers fruit, Wax Mirror Glass, Polyester Alkali (NaOH). The was carried out by soaking in a 15% solution for 2 hours. length this were short (<1cm) long (>8 cm). composition number matrix calculated based volume fraction test spesim...

Hemp fibre reinforced unsaturated polyester composites (HFRUPE) were subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. HFRUPE composites specimens containing 0, 0.10, 0.15, 0.21 and 0.26 fibre volume fraction were prepared. Water absorption tests were conducted by immersing specimens in a de-ionised water bath at 25 C and 100 C fo...

The inverse magnetostrictive effect is an effective property for energy harvesting; the material needs to have large magnetostriction and ease of mass production. Fe-Co alloys being magnetostrictive materials have favorable characteristics which are high strength, ductility, and excellent workability, allowing easy fabrication of Fe-Co alloy fibers. In this study, we fabricated magnetostrictive...

Fiber-reinforced polymer–matrix composites are known to exhibit loading rateand time-dependent mechanical response. Their fatigue strength is determined by a complex interaction of damage processes governed by loading duration and cycle number. Apart from mechanistic approaches, a number of empirical models of various sophistication have been proposed to predict the durability of composites, di...
