Composites: Materials / Process and Defects Analysis

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





Topics covered during the presentation:

Features presented from case studies:

  • Context
  • Ageing of equipment
  • Proof of fatigue strength of steel structures in Europe: Eurocodes
  • Crane design, residual life of cranes and related Rules and Standards
  • Pressure vessels and boilers
  • Cetim’s general methodology for evaluation of Residual Life
  • Some industrial examples
  • Questions answers


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