Influence of manufacturing-induced defects on the fatigue performances of autoclave moulded laminates

In the present work, cross-ply and multidirectional laminates were produced by autoclave moulding. Changes in the process parameters led to different microstructural features in terms of fibre volume fraction, global void content, and void size. Fatigue tests revealed a strong influence of the micro...
