Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...

Polystyrene (PS) is one form of the plastic that most widely utilized for household application. However, plastics made from PS can pollute environment. Hence, it necessary to modify by mixing with a biodegradable polymer like poly (ɛ-caprolactone) (PCL). The focus this research was determine mechanical and thermal properties PS/PCL polyblends. In research, polyblend are prepared PCL acquired u...
