STORAGE-STABLE 1K POLYURETHANE PREPREGS AND SHAPED BODIES MADE OF POLYURETHANE COMPOSITIONS PRODUCED FROM THOSE PREPREGS

摘要

PROBLEM TO BE SOLVED: To provide: a simpler process for producing polyurethane-based prepreg systems allowing problem-free handling that are based on polyurethane compositions; prepregs comprising polyurethane matrix material which can be produced by a simple process; and moldings produced from the prepregs.SOLUTION: A prepreg essentially comprises A) at least one fibrous carrier and B) at least one polyurethane composition, where the polyurethane composition has a Tg of less than 40°C and comprises an essentially internally blocked and/or blocking agent-blocked di- and/or polyisocyanates and/or polyaddition compounds thereof.SELECTED DRAWING: None
