Abstract

Si utilizza un'anima a perdere cava formata da due semigusci giustapposti, sulla quale vengono avvolti, in fasi successive, diversi fogli o tessuti di fibra di carbonio, che cono compattati con l'ausilio di uno stampo; all'interno dell'anima cava è inserito, prima della giustapposizione dei gusci formanti la stessa, un sacco a tenuta di fluido realizzato in un materiale sintetico; la compattazione dei diversi strati è effettuata disponendo il semilavorato formato dall'anima, dal primo sacco e dal/i foglio/i di fibra entro lo stampo e realizzando una differenza relativa di pressione fra l'interno e l'esterno del sacco tale che la pressione all'interno del sacco sia maggiore di quella all'esterno dello stesso e dello stampo e produca lo schiacciamento dei semigusci dell'anima e del/i foglio/i contro le pareti interne dello stampo.(Figure 2 e 6)
