Deposition defects arising during automated fibre placement (AFP) reduces production rate and creates wastage from rejected parts. This issue can be alleviated by identifying and reacting to those defects in real-time during deposition. To demonstrat

The presence of voids in composite materials reduces the material’s strength, particularly matrix-dominated properties such as short beam shear (SBS) strength. Until now there has been no satisfactory way to reliably predict the effect of voids on

To investigate and evaluate the effect of void features on the mechanical performance of composite materials, it is important to be able to manufacture samples with a range of controlled void content. A criterion of less than 2% of porosity is typica

Porosity in composites is a critical manufacturing defect that leads to a reduction of mechanical performance. Non-destructive testing (NDT) techniques are used to inspect composites after manufacture to identify defects and to help assess their impa
