Natural ibre based composites are under intensive study due to their ecofriendly nature and peculiar properties. he advantage of natural ibres is their continuous supply, easy and safe handling, and biodegradable nature. Although natural ibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography, and so forth. Pineapple leave ibre (PALF) is one of the abundantly available wastes materials of Malaysia and has not been studied yet as it is required. A detailed study of chemical, physical, and mechanical properties will bring out logical and reasonable utilization of PALF for various applications. From the socioeconomic prospective, PALF can be a new source of raw material to the industries and can be potential replacement of the expensive and nonrenewable synthetic ibre. However, few studies on PALF have been done describing the interfacial adhesion between ibres and reinforcement compatibility of ibre but a detailed study on PALF properties is not available. In this review, author covered the basic information of PALF and compared the chemical, physical, and mechanical properties with other natural ibres. Furthermore, it summarizes the recent work reported on physical, mechanical, and thermal properties of PALF reinforced polymer composites with its potential applications. 1. Introduction Industries are widely using plant ibres for numerous appli- cations from many resources. In the middle of 20th cen- tury, synthetic ibres rose up drastically, and natural ibres industries collapse its market shares. For promoting natural ibre and material, year 2009 is considered as international year of natural ibre (IYNF), which is highly supportive to famers, agriculture, environment, and market demands. Composite market of United States has been recorded 2.7– 2.8 billion pounds from 2006 to 2007. On the basis of compound annual growth rate of 3.3%, it is estimated to cross over 3.3 billion pounds [1]. In 2009, hailand produces 1.894 million tonnes, the Philippines produced 2.198 million tonnes, and Brazil produced only 1.43 million tonnes. In 2001 the production of Costa Rica, Cote d’lvoire, and Philippines were 322,000 tonnes, 188,000 tonnes, and 135000 tonnes, respectively [2]. he most important property of natural ibre is biodegradability and noncarcinogenic which bring it back into fashion, with an advantage of being cost-efective. he versatile nature of it makes it suitable for automobiles, railway coach, building construction, partition wall cabinets, or furniture for machinery uses and packaging. Natural ibres are important agricultural biomass contributing to Malaysian economy. he huge and wide range availability of natural ibre can reduce the pressure on forest and agriculture. he usage of diverse raw materials will help to keep a ecological balance in nature. Generally agriculture materials and forest product produce 30–40% waste materials, which can also be used in value added processing. he low density Hindawi Publishing Corporation International Journal of Polymer Science Article ID 950567
