The Plant fibers have cellulose fibrils dispersed in a matripilx of lignin and hemicelluloses. They also have small amounts of free carbohydrates, proteins, extractives, and inorganics. For plant fibers cellulose is the basic structural component and the most abundant naturally-occurring polymer on earth. Hemicelluloses are polysaccharide polymers comprised of shorter polymer chains than cellulose. Lignin is an amorphous polymer of phenol-propane units. It can be a trusting agent which gives their rigidity to cell walls of plant. The content of lignin in bamboo is more than many other natural fibers, which make it brittle.
Abstract— Hybrid composites are advance conceptual composite materials. These are that materials which contains two or more non similar types of natural/synthetic fiber in one of the fiber could neutralize the deficiencies in the other. Due to hybridization high corrosion resistance property of natural fiber increases as compare to the synthetic fibers like glass fiber have improved chemical & mechanical properties. In this paper there is setting a review on hybrid polymer composites reinforced with glass and natural fiber as bamboo fiber based on their biodegradability. The importance of biodegradability is to develop composite materials which are ecofriendly.
1.2 Comparison between Glass fiber & bamboo
Key Words: Biodegradability , Natural fibers, Hybridization , Synthetic fibers, Tensile modulus
The bamboo is also called natural glass fiber because of its strength. The remarkable properties of bamboo fibers as its low density & strength stiffness can be compared with glass fibers. The hybrid composites treated with alkali bamboo fibers were possess higher flexural properties. The surface changes in bamboo fiber will effectively removing the impurities and bond between fibers in which the various compositions classified in the different percentage will get the different results of testing. This is due to the hydrophilic nature of bamboo fiber, where the different methods required for improving interfacial surface adhesion. This means that by understanding the fiber structures and characteristics which influence to composite performance, it can lead to the highly development of additives, coating, binders, or sizing of the natural fiber and a assortment of polymeric matrices. When specific modulus is considered for lignocelluloses fibers, it shows the values which are comparatively better than glass fibers.
1. Introduction As per environmental prospect natural fibre has many advantages such as lower pollutant emissions, lower green house gas emissions and end of life biodegradability of components. Recently studies proven that performance of natural fiber as per environment prospect is far better than glass fiber[1] over its specific applications. In many application natural fiber shows superiority over the glass fiber composite due to having more fibre content and low impact on environment. It has also another properties like low weight density and less emission when they are going to use. As decay in carbon credit & energy it causes biodegradability in natural fibre. 1.1 Importance of Bamboo Fiber The reason why bamboo fibre is more prefer over another natural fibre is that its ecofriendly nature as rate of growth high, low carbon emission and easy availability.The properties of bamboo arehigher strength and low weight more stiffness.It has also roots and leave which keep the soil together and protect it against the sun respectively. Because of these properties bamboo can be used traditionally for manufacturing of living utilities. For reinforced composite materials base bamboo can be used on extracting appropriate fibers in suitable manner. Bamboo is the last sustainable plant resource which has not been used vastly .Studies have done over natural fibre as reinforcements for both synthetic
