摘要： A pre-impregnated yarn having a bundle made of reinforcing fiber filaments impregnated with a first resin composition infiltrated into the pre-impregnated yarn and at least partially connected via the first resin composition. The first resin composition contains at least two bisphenol A epichlorohydrin resins H1 and H2 in a weight ratio H1:H2 of 1.1 to 1.4, and an aromatic polyhydroxy ether P1. The pre-impregnated yarn has a second resin composition on the bundle outer side in the form of adhesive particles or drops. The second resin composition is solid at ambient temperatures and has a melting temperature in the range from 80 to 150° C. The bundle interior and at least 50% of the surface of the bundle outer side are free of the second resin composition.
