Abstract: In the current study, flexural strength of combination of natural and synthetic fiber with particle filled hybrid composites have been studied. The flexural strength of the hybrid composite mainly depends on the proportion of the sisal fiber weight, glass fiber weight and alumina weight. Taguchi technique has been applied to find the optimized parameters of the developed hybrid composites. Results were obtained for the L9 orthogonal combination from experimentation. The results were analysed with the help of Signal/Noise (S/N) Ratio, Main effect plot and Analysis of variance (ANOVA) using Mini Tab 19. Regression equation are developed for all three reinforcements separately. From the current study it was observed that the flexural strength of the hybrid composite mainly depends on the sisal fiber precent that the other two reinforcements. Based on the experimental observations the maximum ultimate flexural strength was found to be 145.97 MPa for optimised input parameters as 20% of sisal fiber, 20% of glass fiber and 2% of alumina.

Response Optimization

Natural fibers composite play an important role in making eco-friendly products. The present investigation has been made to find tensile strength of hybrid composites fabricated using optimal composition of sisal fiber, glass fiber and alumina. Multi-response optimization has been carried out. The compositions of reinforcements namely sisal fiber, glass fiber and alumina in hybrid composite were prepared by Hand-layup technique. Sisal fiber of 20 Wt.%, 30 Wt.% and 40 Wt.% are chopped into 10mm length, Glass fiber of 20 Wt.%, 30 Wt.% and 40 Wt.% are 10mm length and alumina particles of 2Wt.%, 3 Wt.% and 4 Wt.% are compositions of reinforcement were chosen according to orthogonal array as Taguchi technique(L9). The results have been verified through confirmatory experiments. Experimentations were carried out with the different composition based on L9 process parameters. Based on the experimental observations the maximum ultimate tensile strength was found to be 37.87 MPa for optimised input parameters as 20% of sisal fiber, 30% of glass fiber and 3% of alumina.

In this research work an attempt is made to fabricate a hybrid composite material with hessian cloth (natural fiber) and glass fiber (synthet ic fiber) in polyester matrix using hand lay-up process and testing was performed by ASTM standards. Main objective of this research work is to investigate the effects of use of natural fiber in the composite material with the synthetic fiber. Experimental results revealed that hybridization of composite with natural and synthetic fibers shows promising tensile strength, flexural strength and hardness. Among the hybrid composites one with the composition of three layers of glass fibers and two layers of hessian cloth (jute fiber) showed highest ten sile strength and flexural strength which were found 104.63 MPa and 134.65 MPa respectively. Water absorption was high in composites having higher hessian cloth content than glass fiber. Composite with high glass fiber content showed high hardness which was 39.9 HV.Bangladesh J. Sci. Ind.

Study Results

This study aims to explore the mechanical properties of hybrid glass fiber (GF)/sisal fiber (SF)/chitosan (CTS) composite material for orthopedic long bone plate applications. The GF/SF/CTS hybrid composite possesses a unique sandwich structure and comprises GF/CTS/epoxy as the external layers and SF/CTS/epoxy as the inner layers. The composite plate resembles the human bone structure (spongy internal cancellous matrix and rigid external cortical). The mechanical properties of the prepared hybrid sandwich composites samples were evaluated using tensile, flexural, micro hardness, and compression tests. The scanning electron microscopic (SEM) images were studied to analyze the failure mechanism of these composite samples. Besides, contact angle (CA) and water absorption tests were conducted using the sessile drop method to examine the wettability properties of the SF/CTS/epoxy and GF/SF/CTS/epoxy composites. Additionally, the porosity of the GF/SF/CTS composite scaffold samples were determined by using the ethanol infiltration method. The mechanical test results show that the GF/SF/CTS hybrid composites exhibit the bending strength of 343 MPa, ultimate tensile strength of 146 MPa, and compressive strength of 380 MPa with higher Young’s modulus in the bending tests (21.56 GPa) compared to the tensile (6646 MPa) and compressive modulus (2046 MPa). Wettability study results reveal that the GF/SF/CTS composite scaffolds were hydrophobic (CA = 92.41° ± 1.71°) with less water absorption of 3.436% compared to the SF/CTS composites (6.953%). The SF/CTS composites show a hydrophilic character (CA = 54.28° ± 3.06°). The experimental tests prove that the GF/SF/CTS hybrid composite can be used for orthopedic bone fracture plate applications in future.

The Impact

In order characterize the outstanding performance of the three dimensional (3D) hybrid composites, the charpy and flexural test has been carried out. 3D fiber structures have been achieved by using hand lay-up process and machine stitching method. Materials for hand lay-up and machine stitching process were glass fiber, jute fiber, and epoxy resin and nylon fiber respectively. Two dimensional (2D) glass fiber composite and 2D hybrid composite with the same stacking sequence as three dimensional (3D) counterparts have also been fabricated for the comparison of impact and flexural strength. The impact strength of 3D hybrid composite was increased (5-10%) compared with that 2D glass fiber and 2D hybrid composites. The flexural strength and modulus of 3D hybrid composite were increased (5-10%) compared with that of 2D hybrid composites.

In this paper, mechanical properties of bamboo strip and bamboo strip-glass fiber reinforced hybrid composite were investigated. Composites were manufactured by using hand lay-up technique and bamboo strips were made from locally available bamboo. Four layers of bamboo strip composite were manufactured and in case of hybrid composite, two layers of glass fiber one at the top and the other at the bottom were used with the aim was to observe the effect of adding glass fiber layer on the mechanical properties of bamboo strip composite. Tensile and flexural properties were studied and it was found that adding the glass fiber layer doesn’t have any significant effect on tensile properties but flexural strength and modulus have increased by 22.49 % and 15.02 % respectively.

Recent years, Polymer matrix hybrid composites have a greater attention in industry and research due to growing demand for versatile applications. The present work focused on the development of epoxy based hybrid nanocomposites. Nanoclay is another novel material that is widely used in the research. In this investigation, nanoclay dispersed hybrid composite materials has been studied for mechanical and wear behavior. Glass fiber and banana fiber combined epoxy laminates (EGB) were reinforced with nanoclay at different weight fractions of 2%, 4%, 6%, and 8% using compression moulding. The enhanced properties of the nanoclay hybrid composites were analyzed with other specimens. Water absorption character study was also conducted. Morphological study was performed using Scanning Electron Microscope. It was observed that an optimum result attained with 4 wt% nanoclay reinforced composite with an increase in tensile strength of 8.62%, flexural strength of 30.19%, and impact strength of 48.15% when compared to EGB. Further the wear resistance of 4 wt% nanoclay hybrid composite showed an increase of 19.4% than the EGB composite.
