TL;DR: In this article, the authors addressed the results of experimental investigation on the mechanical properties and free vibration behaviors of sisal/cotton fabric reinforced polyester hybrid composites and found that an increase in the lamina content in the composite increase the mechanical and damping properties.
Abstract: The present research work addressed the results of experimental investigation on the mechanical properties and free vibration behaviours of sisal/cotton fabric reinforced polyester hybrid composites. Influence of fibre content and changing layer pattern (CLP) on the mechanical properties and free vibration characteristics are analysed. Hybrid composites are fabricated with simple hand lay-up method followed by compression moulding process. Natural frequency and modal damping values of hybrid composites are analysed by experimental modal analysis. Mechanical properties of composites are measured according to ASTM standards. It is found that an increase in the lamina content in the composite increase the mechanical and damping properties. The maximum mechanical properties are obtained for 40% fibre volume fraction (Vf) in sisal and cotton direction. Maximum natural frequency is found at 40% fibre Vf. By CLP, mechanical properties and damping characteristics are found intermittence of sisal and cotton direct...

TL;DR: In this article, the impact properties of hybrid composites manufactured with the aim of improving their structural characteristics, and in particular, is focused on the impact resistance and penetration behaviour of hybrid composite reinforced with natural and synthetic fibres as well as their suitability for modern structural applications.
Abstract: Recently published research indicates that natural fibre based polymer composites have limited applications in advanced structural systems due to their low impact performance. However, natural fibres have great potential for reducing the product weight, lowering material cost, and renewability. Hybrid composites made from a combination of natural/synthetic fibres, natural/natural fibres, or synthetic/synthetic fibres are also receiving attention from both researchers and the industry for structural applications owing to the tailored mechanical and impact properties of these materials. The hybridisation process is one of the paramount and more efficient ways to strengthen and improve the performance of composite materials. This review paper examines the impact properties of hybrid composites manufactured with the aim of improving their structural characteristics, and in particular, is focused on the impact resistance and penetration behaviour of hybrid composites reinforced with natural and synthetic fibres as well as their suitability for modern structural applications.

TL;DR: In this paper, the void content, tensile, vibration and acoustic properties of kenaf/bamboo fiber reinforced epoxy hybrid composites were investigated using the hand lay-up method.
Abstract: This study aims to investigate the void content, tensile, vibration and acoustic properties of kenaf/bamboo fiber reinforced epoxy hybrid composites. The composites were made using the hand lay-up method. The weight ratios of kenaf/bamboo were 30:70, 50:50 and 70:30. Further, kenaf and bamboo composites were fabricated for the purpose of comparison. The hybridization of woven kenaf/bamboo reduced the void content. The void contents of hybrid composites were almost similar. An enhancement in elongation at break, tensile strength and modulus of hybrid composites was observed until a kenaf/bamboo ratio of 50:50. Kenaf/bamboo (50:50) hybrid composite displays the highest elongation at break, tensile strength and modulus compared to the other hybrid composites which are 2.42 mm, 55.18 MPa and 5.15 GPa, respectively. On the other hand, the highest natural frequency and damping factors were observed for Bamboo/Kenaf (30:70) hybrid composites. The sound absorption coefficient of composites were measured in two conditions: without air gap and with air gap (10, 20, 30 mm). The sound absorption coefficient for testing without air gap was less than 0.5. Introducing an air gap improved the sound absorption coefficient of all composites. Hence, hybrid kenaf/bamboo composites exhibited less void content, as well as improved tensile, vibration and acoustic properties.

TL;DR: In this article, the tensile properties of hybrid composites were found to increase substantially with increasing jute fibres loading as compared to oil palm-epoxy composite, and the overall use of hybrid system was found to be effective in increasing tensile and dynamic mechanical properties of the oil palm/polyurethane composite probably due to the enhanced fibre/matrix interface bonding.
Abstract: Hybrid composites prepared by hand lay-up technique by reinforcing jute and oil palm fibres with epoxy matrix. The tensile properties of hybrid composites were found to increase substantially with increasing jute fibres loading as compared to oil palm–epoxy composite. The nature of fibre/matrix interface was examined through scanning electron microscopy of tensile fracture samples. Addition of jute fibres to oil palm composite increases the storage modulus while damping factor shifts towards higher temperature region. Cole–Cole analysis was made to understand the phase behaviour of the composite samples. The hybrid composite with oil palm:jute (1:4) showed maximum damping behaviour and highest tensile properties. The overall use of hybrid system was found to be effective in increasing tensile and dynamic mechanical properties of the oil palm–epoxy composite probably due to the enhanced fibre/matrix interface bonding. The potential applications of the oil palm based hybrid composites in automobiles and building industry are going to increase in near future.

TL;DR: The fiber reinforced hybrid composites consist of two or more fiber in a matrix system as mentioned in this paper and different fibers were reinforced with suitable matrix for preparing the hybrid composite using various manufacturing methodology.
Abstract: The polymer matrix composites have been widely used for many applications. These are light in weight and easy for manufacturing. The hybrid fiber reinforced composites have been prepared to enhance the mechanical, thermal, damping properties compared to single-fiber reinforced composites. The fiber reinforced hybrid composites consist of two or more fiber in a matrix system. The different fibers were reinforced with suitable matrix for preparing the hybrid composites using various manufacturing methodology. The hybrid composites are used for many application and replacing wood, wood fiber composites and conventional materials. The mechanical properties (tensile, flexural and impact), dynamic, tribological and water absorption properties of natural fiber reinforced hybrid polymer composites and natural/synthetic fiber reinforced hybrid polymer composites were reported.

TL;DR: In this paper, the tensile and flexural performance of tri layer oil palm empty fruit bunches (EFB)/woven jute (Jw) reinforced epoxy hybrid composites subjected to layering pattern has been experimentally investigated.
Abstract: In this research, tensile and flexural performance of tri layer oil palm empty fruit bunches (EFB)/woven jute (Jw) fibre reinforced epoxy hybrid composites subjected to layering pattern has been experimentally investigated. Sandwich composites were fabricated by hand lay-up technique in a mould and cured with 105 °C temperatures for 1 h by using hot press. Pure EFB and woven jute composites were also fabricate for comparison purpose. Results showed that tensile and flexural properties of pure EFB composite can be improved by hybridization with woven jute fibre as extreme woven jute fibre mat. It was found that tensile and flexural properties of hybrid composite is higher than that of EFB composite but less than woven jute composite. Statistical analysis of composites done by ANOVA-one way, it showed significant differences between the results obtained. The fracture surface morphology of the tensile samples of the hybrid composites was performed by using scanning electron microscopy.
