  By M Chrispin Das, S Prathap Singh, R Malkiya Rasalin Prince, K. Gnanasekaran, S Manikandan, A Dhanush, D S Sujith Kumar, S Yuva Praveen

  Abstract: In this study, the effect of alkali treatment on the tensile strength of the hibiscus fiber, gongura fiber, and treated madar fiber-reinforced Polymer Matrix Composite (PMC) is studied. The Sodium Hydroxide (NaOH) solution is utilized for madar fiber treatment. The traditional hand layup methodology was used for fabrication. The influence of tensile property control variables such as duration of fiber treatment, concentration of NaOH for treatment, and proportion of fiber …

  Fabrication and drilling characterization of Hemp & Grewia-Optiva hybrid composite and comparison with ANN model

  By Ankit, Rishu Kesharwani, Satyavrat, Dungali Sreehari

  Abstract: In recent days the use of natural fibers has increased over synthetic fibers due to various advantages. The alkali treatment for these natural fibers further improves the adhesion between fiber and matrix and greatly enhances the mechanical properties of the composite. The present study involves the fabrication of a hybrid composite using the alkali-treated (5% NaOH concentration) natural fibers – Hemp &Grewia-optiva as reinforcement material and epoxy as a matrix …
