in space manufacturing, materials need to be warmed from cold space temperature before heated to industry production temperature

at the beginning of space industrialization, 

could carbon fiber be a more viable material than steel for industry production in space since probably a lot less heat is needed in carbon fiber production compared to steel production 

steel production requires a lot of heat and space is very cold, 

so steel materials need to to be warmed from -270 degrees celcius, 

before steel materials are heated to industrial processing temperature 

there is a lot of both steel and carbon available in asteroids in the asteroid belt, 

but most likely less heat is needed to extract carbon than steel from asteroids 

access to enough energy is not the problem because of solar energy, 

but heating in cold space temperature could be the issue
