Abstract

Elementi in materiale composito sono realizzati a partire da fogli pre-impregnati o laminati (1) inserendo i fogli all'interno di una cavità (2) chiusa di stampaggio definita tra almeno due semistampi accostati (3, 4) e previa stesura di un distaccante, in cui almeno un semistampo ha una impronta (5) di forma coniugata con quella dell'elemento da ottenere, ed introducendo poi nella cavità di stampaggio, preferibilmente all'interno di una zona (15) isolata dai semistampi e dai fogli in materiale composito mediante interposizione di fogli di rivestimento (11, 12), un materiale fluido pressurizzato (10) atto a compattare i fogli (1) sull'impronta (5) ed a riscaldare i fogli (1) alla temperatura di polimerizzazione; i fogli laminati sono rammolliti direttamente tra i semistampi (3, 4), che definiscono dei controelettrodi collegati ad un generatore (20) ad alta frequenza.(Figura 1)
