To address the sustainable development goals, an attempt was made to investigate the alkaline treated and untreated Banana, Sisal, and Pineapple fiber epoxy hybrid composite for their mechanical and thermal properties. Tensile, Flexural, Impact, modulus, and Heat Deflection temperature (HDT) were evaluated and analyzed for low-load structural applications. The performance of Alkaline Treated Fiber composites was better than the untreated fiber composites. The treated Banana, Sisal, and Pineapple hybrid fiber epoxy composite has a high HDT value of about 78°C, a maximum tensile strength of 104 MPa, a tensile modulus of 25 MPa, a flexural strength of 78 MPa, a flexural modulus of 5286 MPa, and an impact strength of 286 J/m when compared to other composites. Interfacial failure analysis was also carried out with the help of a Scanning Electron Microscope (SEM) to study the microstructural behavior of the tested specimens. It was observed that the alkaline treatment increases fiber-matrix interaction.

“…Furthermore, by studying the glass-carbon fiber hybrid composites pipes, it was found that the same properties of the single carbon fiber composite could be obtained by using the hybrid composites, thus resulting in a cost reduction [4]. For example, a study of eco-friendly hybrid composites with banana and sisal reinforcements concluded, that a significant loss of mechanical strength occurred when compared to the composites with single type of reinforcement [5]. In contrast, Kevlar/epoxy resin composite reinforced with nano-silica particles possessed superior mechanical properties compared with Kevlar composites [6].…”

Mechanical Testing and Modeling of the Time–Temperature Superposition Response in Hybrid Fiber Reinforced Composites

The purpose of this study was to manufacture hybrid composites from fabrics with superior ballistic performance, and to analyze their viscoelastic and mechanical response. Therefore, composites in hybrid lay-up modes were manufactured from Vectran, Kevlar and aluminum fiber-woven fabrics through a vacuum assisted resin transfer molding. The specimens were consequently analyzed using static three-point bending, as well as by dynamic mechanical analysis (DMA). Apart from DMA, time–temperature superposition (TTS) analysis was performed by all available models. It was possible to study the intrinsic viscoelastic behavior of hybrid ballistic laminates, with TTS analysis gained from creep testing. A polynomic mathematical function was proposed to provide a high accuracy for TTS curves, when shifting out of the linearity regimes is required. The usual Williams–Landel–Ferry and Arrhenius models proved not useful in order to describe and model the shift factors of the acquired curves. In terms of static results, the highly nonlinear stress–strain curve of both composites was obvious, whereas the differential mechanism of failure in relation to stress absorption, at each stage of deformation, was studied. SEM fractography revealed that hybrid specimens with Kevlar plies are prone to tensile side failure, whereas the hybrid specimens with Vectran plies exhibited high performance on the tensile side of the specimens in three-point bending, leading to compressive failure owing to the high stress retained at higher strains after the maximum bending strength was reached.

“…Lightweight and high-strength polymer composites are used in many industries, but Natural fibers are cheaper, less dense, biodegradable, renewable, and recyclable than synthetic fibers. 1 The composite material combines two or more materials with and reinforcement matrix. The role of matrix material is to hold the reinforcement material and maintain it in the predetermined directions.…”

Natural fibers such as Banana fiber and sugarcane bagasse powder are used in the present study, which are abundantly available at low cost. Novel hybrid natural fiber reinforced composite specimen prepared by using the matrix material as epoxy (70%) with the addition of hardener and the reinforcement material (30%) used as NaOH chemical treated banana fiber with the addition of filler material as sugarcane bagasse powder to enhance the property. To prepare the composite material hand-lay process is used and manufactured three different combination of specimen by varying the composition ration of 10%, 15%, and 20% of reinforced material. The mechanical properties such as tensile, compression, flexural, Impact test of the prepared specimen have been evaluated as per the ASTM standards. The mechanical properties results depicts that the specimen prepared with chemically treated fiber gives more strength as compared to untreated fiber composites. The morphological study evidences the proper fiber used while preparing the hybrid composite material. The maximum tensile strength achieved in specimen is 73.48 MPa, compressive strength of 99.63 MPa, flexural strength of 77.50 MPa, Impact strength of 4.8 J/mm, Vickers hardness value of 59.6. The specimen prepared with chemically treated specimen has a higher percentage of water absorption than the untreated. This novel hybrid composite material can be used in automobile, aircraft, building, sports, and household applications.
