Methods of making prepregs are described. The methods include the steps of forming a fiber-containing substrate, and contacting the fiber-containing substrate with a resin mixture. The resin mixture may include polymer particles mixed in a liquid medium, and the polymer particles may be coated on the fiber-containing substrate to form a coated substrate. The liquid medium may be removed from the coated substrate to form the prepreg. The prepregs may be used to make fiber-reinforced articles.

The invention pertains to the fields of chemistry and mechanical engineering and relates to glass fiber surfaces which are modified without sizing material and silane, which glass fiber surfaces can be further processed into and used as composite materials, for example as reinforcing fiber materials for plastics, and to a method for producing the modified glass fiber surfaces. The object of the present invention is to provide glass fiber surfaces modified without sizing materials and silane, which glass fiber surfaces exhibit improved properties overall and for a further processing into composite materials, and furthermore to provide a simple and cost-effective method for producing glass fiber surfaces modified in such a manner. The object is attained with glass fiber surfaces modified without sizing material and silane, which glass fiber surfaces are at least partially covered at least with a hydrolysis-stable and/or solvolysis-stable cationic polyelectrolyte and/or hydrolysis-stable and/or solvolysis-stable cationic polyelectrolyte mixture and/or with a hydrolysis-stable and/or solvolysis-stable polyelectrolyte complex and coupled to the glass fiber surface via a (polyelectrolyte) complex formation process by means of ionic bonding, with the polyelectrolyte complex A thereby being formed.
