Abstract

See full text

A throughflow cylinder made at least partly of fiber-reinforced plastic including glass fibers, aramide fibers, carbon fibers, and/or carbon-reinforced plastic (CRP). The matrix material of the fiber-reinforced plastic includes a material heat resistant at least up to 300.degree. C. such as a resin. At least one fiber layer is provided such that the coefficient of thermal expansion .alpha. of the fiber-reinforced plastic is lower than that of steel at approximately 300.degree. C. and preferably lies in a region of 0.ltoreq..alpha.<910.sup.-61/Kelvin. The manufacture of the fiber-reinforced plastic, for example carbon fiber-reinforced plastic, is such that more than approximately 30%, in particular more than approximately 50% and preferably more than approximately 70% of the fibers are oriented at least substantially in the peripheral direction.
