H2: Design and development of advanced ceramic fibers, interfaces, and interphases in composites: A symposium in honor of professor Roger Naslain

HTCMC9_750x120_new

 

Ceramic fibers are key components of ceramic matrix composites. Although advanced ceramic matrix composite materials have been developed with fibers available on the market, there is still demand for fiber materials with even better high-temperature performance. Oxide fibers have limitations due to creep and grain growth, and nonoxide fibers are not stable against oxidation at high temperatures, while both are sensitive to subcritical crack growth. Research is focused on shifting the temperature limit to higher temperatures and on improving long time performance of fibers. Beyond fibers and the matrix materials themselves, the interface or interphase between fibers and the matrix plays an important role in performance of the ceramic matrix composite in terms of fracture toughness and damage tolerance. The interface can also be a protective layer for the fibers, consisting of specially designed interphases.

 

This international symposium is held in honor of professor Roger Naslain and recognizes his outstanding contributions to science and technology of advanced ceramic fibers, interfaces or interphases, ceramic matrix composites, and carbon–carbon composites and his tireless efforts in promoting their wide-scale industrial applications. The aim of this symposium is to discuss advances in ceramic fiber and interface or interphase developments and performance of these materials at high temperatures.

 

Proposed session topics:

• New developments in oxide and nonoxide ceramic fibers

• Characterization and evaluation of temperature-dependent properties of ceramic fibers

• Performance of ceramic fibers in extreme environments (gas turbines)

•Textile processing of ceramic fibers for producing fabrics and preforms

• Nanotube or nanofiber reinforcement

•Interfaces or interphases in ceramic matrix composites
