PROCEDE ET DISPOSITIF DE REALISATION D'UN PROFILE EN MATERIAU THERMOPLASTIQUE RENFORCE PAR DES FIBRES, COMPRENANT UNE ETAPE DE MISE EN TENSION DES FIBRES AU COURS DE LEUR IMPREGNATION

摘要

The production process uses a device for producing the profile comprising at least one impregnation chamber (6) and means for circulating the fibres from upstream to downstream of the device and comprises the following steps:•- introducing fibres (2) into the impregnation chamber (6) and circulating them therein,•- injecting a thermoplastic material into the impregnation chamber (6) so as to obtain a preform of the profile made of thermoplastic material reinforced by fibres (2),•- producing the profile from the preform. The process comprises a step of tensioning the fibres (2) inside the impregnation chamber (6), the thermoplastic material being injected directly onto the taut fibres (2) inside the impregnation chamber (6).
