Abstract

Produzione di un laminato multistrato da un foglio o un nastro comprendente una predeterminata quantità di fibra e di polimero attraverso le seguenti fasi a) si prepara un adatto provino,b) si determinano i necessari valori sperimentati su detto provino,c) si produce un laminato costituito da almeno due fogli orientati secondo due angoli predeterminati e da almeno un foglio orientato secondo un terzo angolo determinato introducendo i suddetti valori sperimentali nelle espressioni proprie della teoria della laminazione.
