Evaluation of impact, thermo‐physical properties, and morphology of cornhusk fiber‐reinforced polyester composites

Abstract

This study aims to investigate the thermo-physical and morphological morphology of cornhusk fiber-reinforced polyester composites. The content of corn husk fiber (CHFs) has been varied, namely 20, 30, 40, and 50 (% vol.) in the polyester composite, respectively. The hot press technique has been used in the manufacture of these composites, then properties were investigated through thermo-physical tests including differential scanning calorimetry, thermogravimetry, Fourier transforms infrared, impact strength properties, and morphology using SEM. The results showed that the composite containing 30% CHF (KJP2) was found to have the most optimal impact strength (4.25 KJ/m 2 ), and the best thermal resistance properties were found in the KJP3 composite, compared with other composites; due to CHF dispersion and good interfacial adhesion between CHF and polyester. SEM images of the fracture of the impact test specimens of the composites show better interfacial bonding between CHFs and polyester.

Influence of calcium carbonate fillers on pine fiber reinforced polyester composites

“…The maximum percentage of cellulose contents present in the PF is responsible for tensile strength and modulus values. [ 66,67 ] The PF3/CCP5 and PF3/CCP10 composites had tensile strengths of 79.49 and 96.51 MPa or decreased by 33.54%–19.28% as compared to without filler composite PF3. This indicates that the fillers have no significant influence on the tensile strengths of PF reinforced composites.…”

Aging effects on free vibration and damping characteristics of polymer‐based biocomposites: A review

“…The composite constitutive parameters, such as fiber aspect ratio, stack sequence, and constituent properties, influence sound absorption and vibration damping qualities. [145,[147][148][149][150][151][152] K. Senthilkumar et al [153] investigated the dynamic behavior of banana/sisal hybrid composites reinforced with epoxy, looking at the influence of banana fiber and the study of various fraction constituents, vibration properties such as natural frequency, and mode shapes of sisal/banana fibers reinforced with epoxy resin (L-12), indicating ductile behavior.

Studies on mechanical and thermal properties of cellulosic fiber fillers reinforced epoxy composites

“…In case of cellulose fiber-reinforced composites, the resultant tensile strength is highly dependent on the cellulose contents present in them. [62,63] The higher amount of cellulose content resulted in more tensile strength, which was owing to a higher degree of cellulose polymerization with the epoxy matrix and also the capability of tension resistance. [64] In this current research work, the jute has higher cellulose contents and is then followed by bamboo, and coir fibers.…”
