From last few decades’ composite materials, ceramics and plastics has made a mark in the field of materials. Applications of these materials in engineering arespecially attributed to their low specific weight and comparatively high strength. Applications of composite materials vary from the basic daily needs to sophisticated luxury applications. The demand of natural fiber in the composite materials has been increased owing to low density, low cost and biodegradable properties of natural fiber.But at the same time the natural fibers has certain disadvantages viz. they are hydrophilic in nature due to which there is poor incompatibility of natural fiber with the matrix. This intensity of this disadvantage can be reduced with the help of chemical treatment of natural fibers. Natural fiber has tendency of water absorption, which can also be reduced with chemical treatment. There are number of factors which affect the properties of natural fiber reinforced composite viz. fabrication method, environment condition during fabrication, fiber and its quantity, matrix material. Any slight modification in the above said variables leads to change in the properties of the final composite material. In the present work, the tensile and flexural properties of natural fiber (abaca fiber) reinforced TPU composites have been investigated. The content of natural fiber in composites has been varied from 0 to 30 wt%. The reinforced fibers were chemically treated with NaOH followed by treatment with maleic anhydride in acetone, prior to fabricating of samples by injection moulding. It is observed that the composite containing 10 wt% of abaca fiber has highest tensile strength among all the composites fabricated for this study, whereas the tensile strength of pure TPU sample has maximum among all the samples fabricated during this research work.Maximum flexural strength is observed ofthe composite containing 30 wt% of abaca fiber.SEM examinations of the fractured surface reveal that primary failure mechanisms in composite as fiber fracture and fiber pull-out.

This book provides a comprehensive guide to the large number of diseases, disorders and injuries that can cause severe economic losses to banana, abacá and enset crops, and the fungi, bacteria, phytoplasmas, viruses, nematodes and abiotic factors involved. The monoculture of certain banana cultivars in large plantations make the crop particularly susceptible to catastrophic losses from disease and smallholders can also experience major problems. New approaches to breeding, crop management and handling are being developed to meet challenges posed by emerging threats. Handbook of Diseases of Banana, Abacá and Enset both describes and illustrates diseases and is printed in full colour throughout, creating a valuable diagnostic tool. It covers: - The origin and classification of banana, the safe movement of Musa germplasm and banana breeding for disease resistance. - Recent areas of growing research on the most important diseases of banana, such as black leaf streak, Fusarium wilt, Xanthomonas bacterial wilt and bunchy top. - Significant advances relating to pathogens causing less serious and widespread diseases. Authored by an international team of experts, this is an essential reference for all 'banana doctors' around the world. It serves as a useful field and laboratory guide, as well as a source of information for all those investigating diseases of banana, abacá and enset crops.
