Silica/phenolic composites are used in atmospheric re-entry heat shield parts in spatial and strategic domains. For this application, the material is submitted to thermo-mechanical stresses that lead to delaminations. To ...

We propose a lightweight method for the determination of heat diffusivity of silica fiber bundles based on the use of a laser and an IR camera. The fiber bundle is maintained in traction in a holder; exposition is made as ...
