Analysis of thermomechanical and dynamic characteristics of treated saccharum munja fiber polymer composite

In this study, treated Saccharum munja fibers were considered in particulate (PC), short and random (SRC) and unidirectional (UDC) form along with AW106 Resin and HV953 Hardener as matrix material. Composite laminates were fabricated using a compression moulding machine. Surface treatment of fibers removes dust, lignin and hemicellulose causing better mechanical and free vibration properties. Tensile and flexural tests show the highest value of strength 170 MPa and 143 MPa in the case of UDC composite while the lowest values have been seen in the case of PC. Addition of munja fiber in epoxy matrix enhances the fiber matrix adhesion bonding. The PC composite shows better value of damping than the SRC and UDC composite. The highest natural frequency 43, 233, 298, 849, 918 and 1440 Hz obtained in the case of UDC irrespective of all modes. The highest water absorption rate has been obtained for the SRC while the lowest value was found for PC. Due to the surface treatment of saccharum munja, water absorption properties also improve. The Thermogravimetric shows better stability of UDC. Surface morphology showing the fiber matrix interaction. ANOVA analysis shows that the experimental results output in the case of tensile and flexural tests are significant.
