Bonding a glass-resin composite monofilament to a thermoplastic matrix

Use of a benzoxazine resin (12) for the bonding of a monofilament (10) made of glass-resin composite including glass filaments (101) embedded in a thermosetting polyester resin (102), to a thermoplastic material (14), notably polyester; process for adhering such a monofilament to the thermoplastic m...

Zusammenfassung:	Use of a benzoxazine resin (12) for the bonding of a monofilament (10) made of glass-resin composite including glass filaments (101) embedded in a thermosetting polyester resin (102), to a thermoplastic material (14), notably polyester; process for adhering such a monofilament to the thermoplastic material (14), including at least the following steps: -impregnating the monofilament (10) with a benzoxazine resin (12) in the liquid state; -after impregnation, heat-treating the monofilament (10) thus impregnated, so as to at least partly polymerize the benzoxazine resin (12); -depositing, onto the monofilament (10) thus adhesively coated, the thermoplastic material (14) in the molten state; -after cooling, optionally heat-treating the monofilament thus coated (R-1, R-2) to totally polymerize the benzoxazine resin (12) on contact with the thermoplastic material (14).
