Defects of components of road-building machines operating in a humid environment and in a contact with different liquids have been analyzed. It is found out that the main defects of the components operating in a humid environment are corrosion, cracks in body components, blowholes and malfunction of hole geometry. Traditional methods for removal of the defects, as well as the possibility of the use of polymer composites materials for repair of components of road-building machines operating in a humid environment are described.

Composites Materials- Aircraft, Ship, Automobile. Their most attractive properties are the high strength-to-weight ratio. Polymer composites are used because overall properties of the composites are superior to those of the individual polymers. The natural bio-resin are prepared from neem and Thennamarakudi oil with the concept of polyester resin. The reinforcement is screw pine fibre and fish scale fibre. The aim of this experimental study has targeted to investigate the vibration damping, sound absorption and moisture absorption of reinforced polyester resin polymer composites. The specimen fabricated are naturally bio-degradable and eco-friendly to environment because the resin and fibre are natural ingredients. Mainly to avoid all types of pollution. The laminated specimens were fabricate using hand lay-up technique and the specimens are subjected to the investigated as per the ASTM standards. The Moisture absorption test, Vibration test, Acoustics test were carried out on the laminated specimen to determine their properties.

Components of road-building machines operating under wet environment conditions, and defects characterized for them are discussed. It is shown that most defects for such machines are connected with corrosion. Traditional methods of the reconditioning of the defects are considered on the example of an excavator eye. It has been found out that the promising technique is an application of polymer composite materials.
