Fabrication of composite materials by using short pineapple leaf fiber PALF : A Review

Composite materials (also called composition materials or shorte ned to composites) are materials made from two or more constituent materials with significantly different physi cal or chemical properties,that when combined,produce a material with characteristics different from the i ndividual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons:common examples include materials which are stronger,lighter or less expensive when compared to traditional materials. In the last decades,the use of natural fibers as r einforcement in polymeric composites for technical application has been a research subject of scientist. Interest in natural fibers has increased worldwide due to their low cost,low density,hardness,higher fatigue endurance,good thermal and mechanical resistivity and to their environmental friendliness. The Asian markets have been using natural fibers for many years e.g.,jute is a common reinforcement in India. Natural fibers are increasingly used in automotive and packaging materials. India is an agricultural country and it is the main stay of Indian economy. Thousa nds of tons of different crops are produced but most of their wastes do not have any useful utilization. Agric ultural wastes include wheat husk,rice husk,and their straw,hemp fiber and shells of various dry fruits. These ag ricultural wastes can be used to prepare fiber reinforced polymer composites for commercial use.
