Graphite nozzle rocket
WebThere are two main nozzle materials used in commercial high power rocket motors: graphite (reusable many many times) and glass reinforced molded phenolic (single use). The phenolic nozzles are ablative, just like the larger nozzles. Interestingly, while commonly listed as ablative, graphite isn't actually ablative.
