%X Fiber-polymer composites exhibit extraordianary and unusual properties. Depending on the fiber type and arrangementt the following can be achieved: a very high tensile strength and stiffness or fatigue strength, a zero or negative thermal expension, a rather high damping capability and a very high thermal and electrical insulating performance. But even carbon fibers can be converted into excellent electrical conductors when calined with fluorine. However, the shear properties of fiber composites with a polymeric matrix are medium. Extreme mechanical and thermal cryogenic properties will be discussed and compared to those of other material classes. Special emphasis is put on present and future cryogenic applications including storage and transportation of hydrogen or liquefied gases. Gas permeation through composites afier mechani-cal and thermal cycling and modifications for a better performance will be discassed.Further trends for getting advanced materials will finish the presentation.
