The scope of this thesis is the characterization of a non-crimp 3D orthogonal weave glass fiber textile, used as a reinforcement for composite materials. The analysis was done both in a macroscopic scale as well as in a mesoscopic scale. The mechanical response of textiles was analyzed using biaxial tension testing and transversal compression testing. The internal geometry of the textile was analyzed mesoscopically, while they were subjected to shear strains. The measurement analysis was performed using digital images obtained using micro-ct scanning.
Il lavoro sviluppato in questa tesi riguarda la caratterizzazione di un tessuto “non-crimp 3D orthogonal weave ” in fibra di vetro utilizzato come rinforzo per materiali compositi. Lo studio è stato condotto sia a livello macroscopico che a livello mesoscopico. Nel primo caso è stata analizzata sperimentalmente la risposta a sollecitazioni biassiali di trazione e di compressione trasversale. Lo studio mesoscopico invece ha riguardato la geometria interna del tessuto soggetto a deformazione di taglio. Le misure sono state svolte su immagini digitali ottenute da osservazioni micro-CT.

Abstract
The scope of this thesis is the characterization of a non-crimp 3D orthogonal weave glass fiber textile, used as a reinforcement for composite materials. The analysis was done both in a macroscopic scale as well as in a mesoscopic scale. The mechanical response of textiles was analyzed using biaxial tension testing and transversal compression testing. The internal geometry of the textile was analyzed mesoscopically, while they were subjected to shear strains. The measurement analysis was performed using digital images obtained using micro-ct scanning.File | Dimensione | Formato | |
