Abstract
The invention relates to a method for producing a reinforcement rod (2) from a fibrous composite material consisting of continuous mineral fibers (5, 23, 35) and at least one resin (7, 25), at least one portion of the mineral fibers (5, 23) being mixed with a resin-curing agent mixture, the mineral fibers (5, 23) that have been mixed with the resin-curing agent mixture and, optionally, resin-free mineral fibers (35) subsequently being brought together to form a rod, and the resin (7, 25) being cured. A mixture of at least one resin (7, 25) and at least two different curing agents is used as said resin-curing agent mixture, the two curing agents forming reactive species under different conditions for curing the resin (7, 25) such that the reactive species are available for the curing process at different times.
