Abstract

Procedimiento de fabricación de piezas precuradas en material compuesto con rigidizadores aplicados en estado fresco, que comprende laminar capas superpuestas de material compuesto preimpregnado para obtener una pieza base (1) y una segunda pieza (2) destinada a unirse con ella; curar la pieza base (1); conformar en caliente el laminado destinado a formar la segunda pieza (2); retirar la segunda pieza (2) del útil de conformado de la misma y depositarla sobre la pieza base (1), con intercalación de una lámina de adhesivo estructural entre ambas; encerrar el conjunto de ambas piezas dentro de una bolsa de vacío; y cargar dicha bolsa en un autoclave, realizando en éste un ciclo de curado de la segunda pieza (2) bajo presión y temperatura, con lo cual ésta queda fuertemente adherida a la pieza base (1). La invención es aplicable al campo de la aeronáutica.
