Natural Artificial Fibre Thermostat Composites (NAFTC)

Natural Artificial Fibre Thermostat Composites (NAFTC) are manufactured in our shop floor presently for the Double Glass Windows and Louvers used in Indian Railway. These products have approval of RDSO Lucknow. Sheet Moulding Compound (SMC) is the base line of FRP products.

Artificial fibre that can be composed with natural fibre can make a robust natural fibre for use in the industry. There are manmade synthetic composites like Plywood is a man-made composite that combines natural and synthetic materials. Thin layers of wood veneer are bonded together with adhesive to form flat sheets of laminated wood that are stronger than natural wood.


We have inducted in latest machinery to automate production of these composites mixed with artificial and natural fibre. This will bring our boards of different dimension and specifications.

Nano- and micro-sized synthetic fibers are fully man-made. Fiber-reinforced composites composed of stiffened fiber and matrix are well-known engineering materials. Fiber-reinforced materials have been used in industrial production. Natural fibers can be obtained from many sources in nature such as wool, sisal, ramie, jute, hemp, grass, flax, cotton, coir, bamboo and abaca, banana, and sugarcane. Artificial fibers have been produced from more stiff materials such as glass, single-walled carbon nano tubes, double-walled carbon nano tubes, carbon and polyethylene (PE). The cyclic reusability of materials is an important qualification in protecting the environment from waste pollution. Three important factors can be mentioned in terms of material properties in the recycling process. The first factor is "the rate of cyclic usage," the second one is "less material loss in each recycle," and the last one is "the role of waste products in the self-renewal of ecosystem." In engineering area, the usage of waste materials has taken into account in production of composite materials. The use of waste materials as particulate-type composite production is also possible in the industry. These are the the artificially produced fiber-reinforced materials. Another group of studies focused on the use of sustainable bio-composites and recycled textile wastes as reinforcements in construction.


These NAFTC products are growing popular day by day to bring out rebus board for panel used in Rail roof and body and also in other industrial area.
