摘要

The aim of this study is to assess the effect of stacking sequences involving Ti sheet/Kevlar/jute woven fabric on the mechanical and vibration characteristics of hybrid stacking metal fiber laminates (FMLs). Composite multi stacks, namely, Pure Kevlar, Pure Jute, and multi-stacked with Ti sheet/Kevlar/jute woven fabric, were fabricated through hand layup method involves seven layers of fibre and two outer thin Ti sheet layers. The findings demonstrated that the Kevlar composite (Ti2K9) shows a higher tensile strength (318 MPa), Impact Energy (10.8 J) and Flexural Strength (337 MPa) than the other metal fiber laminates (FMLs) as the Kevlar composite has low wettability and increased strength. Interestingly, Ti2K5J4 tensile strength (273 MPa), flexural strength (312 MPa) and Impact Energy are Ti2K5J4 (273 9.5 J) higher than the other type II and III MFL.Ti2K5J4 obtained a high natural frequency and damping ratio compared to the other type II and Type III MFL. Typically obtained damping ratio of 0.00811 and corresponding natural frequency 712.12 Hz of mode-3. Ti2K9 shows high mechanical and natural frequency characteristics, and Ti2J9 shows high damping ratio characteristics. Ti2K5J4 obtained good mechanical and vibration characteristics.
