FIELD: manufacturing technology.
SUBSTANCE: invention relates to a method for manufacturing a preform, method for manufacturing a composite part and a composite part. Positive effect is reached by proposed method for manufacturing a preform for a composite with a thermoplastic matrix. Said preform comprises one or more layers of reinforcing fibers sewn on a support by means of at least one bonding wire. Method comprises one or several step(s) of depositing a layer of thermoplastic resin on the support or on a layer of reinforcing fibers. Resin layer comprises thermoplastic wires or a first thermoplastic film.
EFFECT: invention enables using of a thermoplastic matrix with preserving mobility of a preform and flexibility of draping.
