CHAPTER 1 The Problem and Its background 1.1 INTRODUCTION The growing interest in the past to produce green materials that can reduce the problem involving waste materials by non-fibrous materials led to the development of natural fiber reinforced thermoplastic composites. Water Hyacinth (Eichhornia crassipes) also known as “water lily” is an aquatic plant which is found floating freely in the surface of fresh waters. Its rate of proliferation under certain circumstances is extremely

carried 20% of carbon and the properties of it were inefficient‚ such as low strength and stiffness ("Carbon (fiber) ‚n.d." ). In the early 1960s the process of Carbon fiber was developed by Dr. Akio Shindo at Agency Of Industrial Science and Technology of Japan‚ which improved carbon fiber and contained 50% of carbon ("Carbon (fiber)‚ n.d." ). In 1963‚ the properties of carbon fiber were acknowledged‚ such as high strength‚ by W. Watt‚ L.N. Philips and W. Johnson at the Royal Aircraft Establishment
