Sizing-free and silane-free modified fiberglass surfaces, composite materials made therefrom, and methods of making the modified fiberglass surfaces

摘要

This invention relates to the fields of chemistry and engineering, and relates to plain and silane-free modified surfaces of glass fibers that can be further processed and used as composites, for example, as reinforcing fiber materials for plastics, and to a method of making the modified glass fiber surfaces This invention is directed to providing plain and silane-free modified glass fiber surfaces having improved overall properties and for further processing into composites, and further to providing a simple and inexpensive process for making such modified fiber surfaces. The object is achieved by modified glass fiber surfaces containing 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 at least partially covered with a hydrolysis-stable and / or solvolysis-stable polyelectrolyte complex and which are coupled via (polyelectrolyte) complex formation by means of ionic bonding to the glass fiber surface to form the polyelectrolyte complex A.
