Journal ArticleDOI
Mercerization Optimization of Bamboo (Bambusa vulgaris) Fiber-Reinforced Epoxy Composite Structures Using a Box-Behnken Design.
Mohamad Zaki Hassan,Siti Amni Roslan,S.M. Sapuan,Zainudin A. Rasid,Ariff Farhan Mohd Nor,Mohd Yusof Md Daud,Rozzeta Dolah,Mohd Zuhri Mohamed Yusoff +7 more
TL;DR: It was found that the optimum mercerization condition lies at 5.81 wt.% of the NaOH, and this optimum alkaline treatment once again had a great effect on the structures whereby all the treated composite cores with square and triangular structures impressively outperformed the untreated bamboo structures.
Journal ArticleDOI
Dynamic mechanical properties of natural fiber reinforced hybrid polymer composites: A review
Nur Izzah Nabilah Haris,Mohamad Zaki Hassan,R.A. Ilyas,Mohamed Azlan Suhot,S.M. Sapuan,Rozzeta Dolah,Roslina Mohammad,M. R. M. Asyraf +7 more
TL;DR: In this article , a review of natural fiber reinforced hybrid composites that emphasize the dynamic mechanical properties is presented, including loss modulus and storage modulus, damping factor, and glass transition temperature.
Journal ArticleDOI
Tensile behaviour for mercerization of single kenaf fiber
Mohamad Ikhwan Ibrahim,Mohamad Zaki Hassan,Rozzeta Dolah,Mohd Zuhri Mohamed Yusoff,Mohd Sapuan Salit +4 more
TL;DR: In this paper, the treatment of single kenaf fibers following tensile test and predicted using analysis of variance (ANOVA) was performed under ASTM D3379-89 standard.
Journal ArticleDOI
Impact Damage Resistance and Post-Impact Tolerance of Optimum Banana-Pseudo-Stem-Fiber-Reinforced Epoxy Sandwich Structures
Mohamad Zaki Hassan,S.M. Sapuan,Zainudin A. Rasid,Ariff Farhan Mohd Nor,Rozzeta Dolah,Mohd Yusof Md Daud +5 more
TL;DR: In this paper, the optimal conditions for a banana/epoxy composite as determined previously were used to fabricate a sandwich structure where carbon/Kevlar twill plies acted as the skins.
Journal ArticleDOI
Physicomechanical Properties of Rice Husk/Coco Peat Reinforced Acrylonitrile Butadiene Styrene Blend Composites.
Nurul Haziatul Ain Norhasnan,Mohamad Zaki Hassan,Ariff Farhan Mohd Nor,Sheikh Ahmad Zaki,Rozzeta Dolah,Khairur Rijal Jamaludin,Sa’ardin Abdul Aziz +6 more
TL;DR: In this article, the effectiveness of these blended biocomposites was evaluated for their physical, mechanical, and thermal properties, including tensile modulus, flexural modulus and impact strength of the 15% rice husk-5% coco peat reinforced acrylonitrile-butadiene-styrene (ABS) composite.
