Pollution and Global Warming

The development of internal combustion engines has actively pursued as the intensity of fuel consumption and environmental regulations for automotive parts has increased, the research speed for the development of lightweight parts has rapidly developed. Composite/carbon fiber reinforced plastics (CFRP) have been extensively developed in the modern automotive industry, and their applications in many military and commercial airplanes are steadily growing because of their enhanced characteristics as well as high strength-to-weight ratio, excellent corrosion/erosion resistance, high design flexibility, and the exceptional ability to withstand high stresses in service while reducing weight. In general, CFRP reinforcement materials are applied according to the externally bonded reinforcement system. Olefin polymer generally used as adhesives for bonding carbon fiber reinforced plastics owing to the outstanding adhesive strength of polypropylene to polypropylene composites. The discovery of carbon nanotubes (CNT) with their extraordinary physical and mechanical properties has led to unique approaches of employing them as ideal reinforcements in advanced nanocomposites. Therefore, in this research, the bonding strength between CFT (continuous fiber thermoplastic) and LFT (long fiber thermoplastic) was developed using CNT reinforced materials. The polypropylene/CNT composite resin was made by mechanical distribution of the CNT in polypropylene. The bonding made between CFT and LFT using this composite is improved by its physical properties. Polypropylene/CNT composites were used for a mechanical adhesion between CFT and LFT.
