BONDING A GLASS-RESIN COMPOSITE MONOFILAMENT TO A THERMOPLASTIC MATRIX

The invention relates to the use of a benzoxazine resin (12) for bonding a monofilament (10), consisting of a glass-resin composite that comprises glass filaments (101) embedded into a thermoset polyester resin (102), to a thermoplastic material (14), particularly polyester; and to a method for the adhesion of such a monofilament to the thermoplastic material (14), involving at least the following steps: impregnating the monofilament (10) with a benzoxazine resin (12) in liquid state; after impregnation, heat-treating the now impregnated monofilament (10) in order to at least partially polymerise the benzoxazine resin (12); depositing, onto the now bonded monofilament (10), the thermoplastic material (14) in molten state; and, once cooled, optionally heat-treating the now coated monofilament (R-1, R-2) in order to fully polymerise the benzoxazine resin (12) in contact with the thermoplastic material (14). 本发明涉及苯并噁嗪树脂(12)用于将由包含嵌入到热固性聚酯树脂(102)中的玻璃丝线(101)的玻璃-树脂复合材料组成的单丝(10)粘结至热塑性材料(14)(特别是聚酯)的用途；以及一种用于将这种单丝粘合至热塑
