Rezumat:
Scopul acestei lucrari este studiul utilizarii fibrelor de carbon in epruvete de lemn pentru testul de incovoiere. Au fost realizate epruvete standardizate pentru testul de incovoiere. Fibre de carbon au fost incleiate in epruvete in diferite moduri. Au fost masurate modulul de elasticitate (MOE) si rezistenta la incovoiere statica (MOR). Au fost utilizate si caracterizate diferite rasini. Un element compozit identic a fost modelat prin Metoda Elementului Finit (FEM) intr-o aplicatie de tip ANSYS. Pentru modelul studiat prin FEM a fost evaluata eficienta cresterii rigiditatii elementului compozit.

Cuvinte cheie:
ranforsare, fibra de carbon, lemn.
