Composites: Materials / Process and Defects Analysis

An overview of composite materials, their properties, the related manufacturing processes and main defects encountered

Discover composite materials and its most commonly used manufacturing processes through application examples. The presentation will also discuss the main defects encountered and the parameters involved.

Topics covered during the presentation:

  • Composites: Overview
  • What do we call “composites” ?
  • Composites: Main manufacturing processes
  • Main defects encountered in composites parts
  • Concept of defects harmfulness
  • How to detect these defects? Non-destructive tests (NDT) applied to composites


The webinar will be presented by our French experts Mr Didier MASTAIN (Methods engineer specialized in composite process) and Ms Sophie TOILLON (Engineer specialized in damage survey of polymer and composite materials)
