Textile materials find wide usage in day today life. Apart from clothing for the human body, there is technical textiles which is used in many fields. Composites have made a very significant advances because of their high strength and stuffiness combined with low weight and less bulk. Life cycle analyses on composites show that, although they can be more expensive to produce, they are generally more environmentally friendly because they consume less fuel during their lifetime compared to the heavier metallic items they replace. Yet composite technology is still in its infancy compared to the use of metals. More advanced fabric structures are being developed. These are extending the score of composites for all industrial applications, including transportation. The use of natural plant fibres as reinforcement in polymer composites for making low cost engineering materials has generated much interest in recent years. New environmental legislation as well as consumer pressure has forced manufacturing industries (particularly automotive, construction and packaging) to search for new materials that can substitute for conventional non renewable reinforcing materials such as glass fibre. One of the main concerns for the use of natural fibre reinforced composite materials is their susceptibility to moisture absorption and the effect on physical, mechanical and thermal properties. The present investigation was designed to study the effect of various factors on the properties of needle punched fabrics, and to enable a detailed understanding to be obtained on the fundamental basis of their mechanical behavior. The selected nonwoven and composites were tested for its mechanical properties such as tensile, flexural and impact properties after the immersion in saline water. The study revealed that there is a overall drop in the mechanical properties of the composites.
