STUDIES ON THE THERMOMECHANICAL PROPERTIES OF NICKEL-PHOSPHOROUS COATED CARBON FIBER FABRIC/POLYESTER LAMINATES

摘要

A systematic study was carried out to investigate the effects of nanoscaled electroless nickel-phosphorous alloy coating on the thermomechanical properties of woven carbon fiber fabric reinforced polyester matrix composites. The electroless nickel-phosphorous coated carbon fiber fabrics with different coating time interval (0, 5, 10, 15, 20, 25, 30mins) were prepared. The polyester matrix was then used to manufacture weave carbon fabric/polyester nanocomposites using wet lay-up process. Dynamic mechanical analysis (DMA) studies were carried out in bending and tensile mode. Experimental results showed Maximum improvements in modulus for 30mins coating time reinforced composites. Dynamic mechanical analysis showed enhancement in thermomechanical properties. The nickel-phosphorous coated carbon fiber fabric composites showed a considerable improvement in the glass transition temperature (Tg).
