Beschreibung
Zusammenfassung:	The invention relates to pre-impregnated yarn made of a bundle of reinforcement fiber filaments, wherein the reinforcement fiber filaments are impregnated with 0.1 to 2 wgt.-% of a first resin composition infiltrated in the pre-impregnated yarn and are at least partially connected via the first resin composition and wherein the first resin composition comprises at least two bisphenol A epichlorhydrin resins H1 and H2 in a weight ratio H1:H2 of 1.1 to 1.4, wherein H1 is solid at room temperature and H2 is liquid at room temperature, and wherein the first resin composition further comprises an aromatic polyhydroxyether P1 having an acid count of 40 to 55 mg KOH/g and an average molecular weight M
