Metal; Ferrous Metal; Austenitic; Cast Iron. Material Notes: Type CRS is an austenitic material with graphite in the nodular form. It conforms to ASTM designation A439-60T and provides much higher strength than type CR with excellent resistance to corrosion, wear and heat.
Tail of a radio-controlled helicopter, made of CFRP. Carbon fiberâreinforced polymer, carbon fiberâreinforced plastic or carbon fiberâreinforced thermoplastic (CFRP, CRP, CFRTP or often simply carbon fiber, or even carbon), is an extremely strong and light fiber-reinforced plastic which contains carbon fibers.he most frequent additive is silica, but other additives such as rubber and carbon nanotubes can be used. The material is also referred to as graphite-reinforced polymer or graphite fiber-reinforced polymer (GFRP is less common, as it clashes with glass-(fiber)-reinforced polymer).
