ABOUT CFRP (CARBON FIBER REINFORCED POLYMER)
Carbon Fiber Reinforced Polymer is a composite material consisting of carbon fibers embedded in an epoxy resin matrix. It offers the highest specific strength and stiffness of any structural aerospace material. CFRP is used in satellite structures, payload fairings, and next-generation launch vehicle tanks including the Rocket Lab Electron first stage.
CHEMICAL COMPOSITION
Carbon fibers (T700/T800/T1100) in epoxy matrix, 55-65% fiber volume
