“…The replacement of the conventional synthetic fibres with natural fibres as reinforcement in the polymer matrix composites could lead to a green, renewable path of applications [1,2]. Natural fibres have received great attention from researchers and industrialists due to their biodegradability, better mechanical properties, easy manufacturing, and overall cost effective quality [3,4]. Apart from this, the lignocellulosic fibres are lightweight, reduce wear in the equipment used for their production, are easily available, renewable, non-abrasive, require less energy for processing, reduce the density of furnished products and absorb CO2 during their growth [5][6][7].…”

Composite materials are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. A hybrid composite refers to a special type of composite which contains more than one fibre material as reinforcing filler. Multiple fibre reinforced composites give a wide variety of mechanical properties with respect to a single fibre containing composite. The ecofriendly nature as well as the processing advantage, light weight and low cost have enhanced the attraction and interest of the natural fibre reinforced composite. The objective of the present research is to study the mechanical properties of the jute-coir fibre reinforced hybrid polyethylene composite. Composites were manufactured by using a hot press machine at three levels of fibre loading (5, 10 and 15 wt%). The tensile, flexural, impact and hardness tests were conducted for the purpose of mechanical characterisation. A water absorption and scanning electron microscopic analysis was carried out as part of the physical evaluation. The tensile test of the composite showed a decreasing trend of tensile strength and an increasing trend for Young's modulus with an increasing fibre content. During the flexural, impact and hardness tests, the flexural strength, flexural modulus, impact strength and hardness were found to be increased with the increasing fibre loading. Water absorption increased with the increase in fibre loading. The scanning electron microscopic analysis showed the strongest adhesion between the fibre and the matrix in the 15% fibre reinforced composite. Based on the fibre loading used in this study, the 15% fibre reinforced composite exhibited the best set of mechanical properties.

“…The choice of constituent materials depends mainly on the specific application and design criteria of the sandwich panel products [1]. The most outstanding benefit of this type of composite structure is its high strength and stiffness to weight ratio [2][3][4][5][6][7][8]. On the other hand, this typical structure also has a few drawbacks; they suffer from strong stress concentration at the interfaces between the face sheets, the weak adhesive layer, and the core, as a consequence of the distinctly different properties of these materials in contact [9].…”

Polymeric composites reinforced with natural fibers have raised more attention as the alternative building materials. In this work, natural fiber composites prepared from jute and hemp fiber were proposed for the intermediate layer of a hybrid sandwich panel. This paper presented the flexural behavior of the newly developed hybrid sandwich panel which included the comparison of the ultimate load, load-deflection behavior, load-strain behavior and failure modes. The study was designed as a single factor experiment where the performance of hybrid sandwich panels containing jute fiber composite (JFC) and hemp fiber composite (HFC) as the intermediate layer was compared to the control (CTR) which was a conventional sandwich panel without an intermediate layer. A static flexural test under a four-point bending load scheme was performed in accordance with the ASTM C 393-00 standard. Aluminium sheet was used as the skins, while expanded polystyrene (EPS) was employed for the core. The testing was performed using a 100 kN servohydraulic machine with a loading rate of 5 mm/min. The applied load, displacement and strains were obtained using data logger. The results demonstrated that the hybrid sandwich panel exhibited a more superior performance than the conventional sandwich panels. The intermediate layer contributed significantly to enhancing the load carrying capacity of the hybrid sandwich panel. The load carrying capacity of hybrid panel with the JFC intermediate layer was 29.60% higher than the conventional sandwich panel, and correspondingly 93.46% higher for the sandwich panel with the HFC intermediate layer.The hybrid sandwich panels also developed a much larger area under the load-deflection curve, indicating greater toughness. The introduction of intermediate layer helped the hybrid sandwich panels to sustain a larger strain prior to reach their ultimate loads, resulting in a higher deformation capability. Indentation and core shear were observed as the failure mode of the conventional sandwich panel. Meanwhile, core shear and delamination were identified as the failure mode of the hybrid sandwich panel.
