ABSTRACT:
A high-temperature resistant stacking support is composed of a, preferably self-supporting, core which at least partially is surrounded by a high-temperature resistant fiber composite made of polyimide fibers of the general formula ##STR1## wherein n is an integer larger than 1 and A represents a four-valent aromatic group.
The stacking support can be produced by shrinking a polyimide fiber nonwoven consisting of polyimide fibers of the general formula (I) onto the core under heat exposure.
These stacking supports are particularly useful for stacking heated aluminum sections.
