Influence of Fiber Volume and Fiber Length on Thermal and Flexural Properties of a Hybrid Natural Polymer Composite Prepared with Banana Stem, Pineapple Leaf, and S-Glass
K.B. Prakash,Yahya Ali Fageehi,Rajasekaran Saminathan,P. Manoj Kumar,S. S. Saravanakumar,Ram Subbiah,B. Arulmurugan,S. Rajkumar +7 more
TL;DR: In this paper, the changes in the thermal properties and mechanical properties of S-glass reinforced with a sodium hydroxide-treated pineapple leaf (PALF) and banana stem fibers were studied.
Journal ArticleDOI
An Unconventional Approach for Analyzing the Mechanical Properties of Natural Fiber Composite Using Convolutional Neural Network
G. Ramkumar,Satyajeet Sahoo,G. Anitha,S. Ramesh,P. Nirmala,M. Tamilselvi,Ram Subbiah,S. Rajkumar +7 more
TL;DR: The natural fiber composites were modeled by using some of the computation techniques to accurately predict the mechanical properties of these composites, including the optimum microstructural model identified by a developed model embedded with a genetic algorithm (GA) optimizer.
Journal ArticleDOI
Tribological Behavior and Analysis on Surface Roughness of CNC Milled Dual Heat Treated Al6061 Composites
TL;DR: In this paper, dual heat treatment (DHT) effect is analyzed using the machining of Al6061-T6 alloy, a readily available material for quickly finding the machinings properties.
Proceedings ArticleDOI
