The present invention relates to a pultrusion molding system comprising a) a pultrusion die and b) a feeding means for introducing a moldable composite material into the pultrusion die. The moldable composite material has been impregnated with a heat-curable resin formulation containing a cationic curing agent for epoxy resins. The cationic curing agent is an aromatic sulfonium salt. The present invention also relates to a process for making a composite article comprising a) feeding a moldable composite material through a pultrusion die, wherein the moldable composite material has been impregnated with a heat-curable resin formulation containing a cationic curing agent for epoxy resins. The heat curable resin formulation is preferably a mixture of at least one multifunctional epoxy resin and a cationic curing catalyst for the epoxy resin.
