Abstract
This paper deals with the study of a new generation of ceramic matrix composites, SiC$_{\rm f}$-SiBC, which consists of a 2.5D perform of SiC fibers and of a self sealing multilayered matrix. Three different batches of these CMCs have been investigated in a morphological point of view thanks to the observations performed at the mesoscopic scale by scanning electron microscopy and automatic image analysis, and also at a microscopic scale by transmission electron microscopy. Through this study, a lot of care was taken about the description of the pyrocarbon interphase and of the different matrix interfaces, which play a key role in the damage features, and more specially in the deflection of the matrix microcracks developed through tested mechanical composites.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
