Sandwich structure composites produced by epoxy core and aluminium skin were developed as potential building materials. Interface bonding between core and skin was controlled by varying kenaf content. Five different weight percentage of kenaf loading ranging from 10 wt% to 50 wt% were employed in the core manufacturing in order to study the mechanical properties of the sandwich composite. Prope...

Improving the mechanical and physical properties of bio-composite materials involves incorporation plant fibers such as Jute, Hemp, Kenaf, Ramie, Sisal, Linen, etc. The existence Diss grass (Ampelodesmos mauritanicus) in abundance east Algeria especially Khenchela region taking into account their resistance low density, which justifies choice use composite materials. Tensile hardness tests for ...

Abstract For the last couple of decades, researchers have been trying to explore eco-friendly materials which would significantly reduce dependency on synthetic fibers and their composites. Natural fiber-based composites possess several excellent properties. They are biodegradable, non-abrasive, low cost, lower density, led growing interest in using these industrial applications. However, prope...

Abstract This study investigated the rheological and mechanical properties of cement composites with kenaf jute fibers for use in shotcrete. The length volume fractions fiber were varied; analyzed terms air content, compression flexural tests conducted, degree dispersion was assessed using fluorescence microscopy. rougher surfaces led to a higher yield stress viscosity composite compared fibers...

Currently, composite board manufacturing using natural fibers has the potential to expand owing environmental awareness. To produce a board, treatment is required improve mechanical and physical properties of fibers. In this study, sodium chloride (NaCl) was used for chemical treatment. However, studies on treatments NaCl are limited. This study aimed investigate characteristics kenaf after The...

cellulose nanofibers (cnf) which isolated from wood and non woody plants have attractive advantages comparing with the synthetic fibers, some of the most relevant being the following: low density, renewable sources, biodegradability, availability, and high specific mechanical properties. recently, the use of cnf in green materials, especially as reinforcement in different polymers has been incr...

Bast fibers, such as ramie, hemp, flax and kenaf, are natural fibers with high specific stiffness strength that have gained increasing attention in recent years. advantageous terms of their biodegradability abundance nature, making them promising candidates for automotive industry, structural composites, pulping textile applications etc. There is a strong desire from industry yielding cellulose...

This study investigates effects of six kenaf cultivars named Cubano, Niger, Cubano 2032, 9277, 7551, and 7566 and three harvesting time stages on the properties of pulp and handsheet paper made from kenaf. Six cultivars of an Iranian kenaf (Hibiscus Cannabinus L.), were planted on 19 May 2007, and harvested after 85, 105, and 135 days. It was understood that with the increase of plant age, fibe...
