Green composites are important class of biocomposites widely explored due to their enhanced properties. The biodegradable polymeric material is reinforced with natural fibers to form a composite that is eco-friendly and environment sustainable. The green composites have potential to attract the traditional petroleum-based composites which are toxic and nonbiodegradable. The green composites eliminate the traditional materials such as steel and wood with biodegradable polymer composites. The degradable and environment-friendly green composites were prepared by various fabrication techniques. The various properties of different fiber composite were studied as reinforcement for fully biodegradable and environmental-friendly green composites.

Nowadays, there has been an increased interest in the applications of bio-composites based on natural fibers, with the increasing emphasis on materials and processes which are environmental friendly and sustainable. Environmental friendly, fully biodegradable reinforced polymers or ‘green' composite materials will play a major role in making the products of the future to protect our environment. The use of biodegradable and environment-friendly plant-based natural fibers has been a promising choice for polymers to make them ‘greener'. In addition to being obtained from renewable sources, natural fibers suitable for composites are biodegradable and have enhanced properties. Bamboo is an excellent example for the development of sustainable natural fibers, since it can grow very fast per day, and the fibers of bamboo have excellent mechanical performance. Additionally, research in the development of bamboo-reinforced composites should be increased in the future, considering their enhanced properties, economical benefits and environmental friendly nature.

Natural Fiber Composite

Researchers have worked on variety of natural fibers reinforced with polymer composites using different parameters to come up with various recommendations. The investigation involved aspects of composition materials and mechanical properties of natural fiber composites. The satisfactory results of natural fiber composites have encouraged researchers to delve deeper into the abilities of natural fiber composite in the form of a core structure. The potentiality of utilizing natural fiber composite in core design has wide potential in modern industries. This paper presents a review on natural fibers and polymer matrices commonly used in core fabrication, core design, fabricating processes of cores, and mechanical properties of cores. Ongoing research of rice husk composites to be fabricated in the form of honeycomb core structures is also discussed.

The forestry and agricultural market have been perceiving outstanding growth due to the advantages of green composites, such as cost effective in nature, environment friendly, excellent mechanical properties, and so on. Various researchers had studied the reinforcement efficiency of various natural fibers in the diverse polymer matrices. Herein, we reported the characterization of microfiber handsheet-molded thermoplastic green composites developed from the combination of oil palm empty fruit bunch (OPEFB)-based microfiber pulp as filler and polyester PP based as matrix. Refined alkaline extracted OPEFB pulp fiber was mixed at different layered composition of the composite of grafted polypropylene. The physical properties and mechanical properties were conducted according to the ASTM standard and showed substantial improvement of the handsheet-molded composite. The scanning electron microgram showed that, as the addition of OPEFB fiber loading increased, there was improved interfacial bonding except for 50% fiber loading which experience fiber pullout. The result also showed improved thermal stability compared with the neat composite. This study will be an effective platform to develop the packaging materials using polymer handsheet composite.

Natural Fiber Composite

Composites are becoming essential part of today’s material because they offer advantages such as low weight, corrosion resistance, high fatigue strength; faster assembly etc. composites are generating curiosity and interest all over the worlds. The attempts can be found in literature for composite materials high strength fiber and also natural fiber like jute, flax and sisal natural fibers provides data but there is need of experimental data availability for unidirectional natural fiber composite with seldom natural fiber like cotton, palm leaf etc., it can provide a feasible range of alternative materials to suitable conventional material. It was decided to carry out the systematic experimental study for the effect of volume fraction of reinforcement on longitudinal strength as well as Modulus of Elasticity (MOE) using developed mould-punch set up and testing aids. The testing is carried out as per ASTM D3039/3039M-08. The comparative assessment of obtained experimental results with literature is also carried out, which forms an important constituent of present work. It is also observed through SEM images and theoretical investigations that interface/interphase plays and important role in natural fiber composite.
