The primary purpose of this study is to realize quantitative fiber loading effects on free vibration, damping behavior, fracture toughness, thermal conductivity, inter-laminar shear strength, and flammability of jute-banana fiber phenolformaldehyde (PF) hybrid composites. These composites were manufactured with fiber weight percentages ranging from 30% to 60% using hot press technique. Hybrid composite with equal amount of fiber and resin (PJB-2) had a higher natural frequency in the range of 4.8%-59%, a higher inter-laminar shear strength varying from 30% to 54%, a higher fracture toughness with minimum of 19 to maximum of 44%, and a low damping factor in the range of 25%-59% to that of other composite having unequal amount of fiber and resin loading. In contrast to other composites, the composite containing 30 wt% fiber (PJB-4) has a high heat conductivity of about 10%-20%. However, the thermal conductivity of jute-banana fiber PF composites declined as the fiber content increased beyond 30 wt%, while the flame resistance was improved as the resin concentration increased. Additionally, Scanning electron microscopy (SEM) studies clearly indicates the failure patterns of fiber matrix interface under Inter laminar shear strength and fracture toughness tests were supports to justify the experimental results.

“…This is comprehensible due to the need for avoiding the resonance phenomenon, which is harmful to complex systems while vibrating. There are many scientific activities in the literature that are focused on the field of vibration phenomena and determining the natural frequencies of polymer composites with various applied fabrics and additives [58][59][60][61][62][63]. One of the examples presented in the literature is the PZL SW-4 helicopter, which is reported in [64].…”

In this research, an analysis of polymer composite with the matrix of L285-cured hardener H286 and six reinforcement layers of carbon fabric GG 280 T was provided. It involved a comparison of the dynamical behavior responses for three cases of composite structures in the context of the presence of the mass share modifier. The samples with the addition of a physical modifier with varying mass percentages were investigated by being subjected to dynamic tests with specific parameters, i.e., constant excitation amplitude and vibration frequency in the vicinity of the base resonance zone. The analysis allowed for indicating the relationship between the composition of the prepared composites and their dynamic response via stiffness characteristics. In addition, the investigation resulted in determining the range of harmful dynamical operating conditions, which may contribute to damage to the composite structures.

“…This study determines the delamination factor obtained for Kenaf fiber and its errors. The TiN coated drill was used for drilling the Kenaf fiber reinforced with epoxy (Rajamanickam et al 2019). The delamination factor of 1.024 was during the machining of Kenaf fiber with TiN coated drill in the CNC drilling center (Venkatasudhahar and Velu 2019).…”

Aim: This research is to compare and analyze the delamination factor in CNC drilling of novel kenaf fiber reinforced with aluminum wire mesh sandwich composite and kenaf fiber laminate with (45 o /0 o /45 o ) ply orientation angle. Material and Methods: During the drilling of kenaf fiber reinforced composite, Delamination is a severe problem. The goal of this research is to determine the effect of cycle boundaries on delamination during penetration of (50%) kenaf fiber and (80%) epoxy supported aluminum wire mesh. The kenaf fiber reinforced composite was made using the hand layup process (kenaf+aluminum+kenaf+aluminum+kenaf). A tungsten carbide drilling device with an 8mm diameter was used to drill the manufactured sample. Feed rate (mm/rev), Speed rate (rpm) and drill bit diameter (mm) are the process characteristics that have been considered. The Celestron microcapture software was used to investigate the data collected by taking advantage of the various quantifiable metrics and graphs available. Sample sizes for each group were 20 with pre-test power of 80%, beta=0.05%, and CL 95%. Results: An experimental scan with 20 samples per group is chosen and the delamination factor was scaled for both the working sample and the analysis. During this examination, CNC bores and delamination factors were determined. The results obtained for independent T test statistical analyses in SPSS software was 0.025 (P<0.050). Conclusion:Within the limitations of this study, the analysis of Kenaf fiber laminate with (45 o /0 o /45 o ) ply orientation angle has produced a delamination factor of of 1.38949 for the samples reinforced with Aluminium mesh and the mean delamination factor of 1.65830 for samples reinforced without Aluminium mesh with an improvement of 16.2% in reducing delamination factor comparing base materials.
