Long term degradation of resin for high temperature composites
The durability of polymer matrix composites exposed to harsh environments is a major concern. Surface degradation and damage are observed in polyimide composites used in air at 125-300°C. It is believed that diffusion of oxygen into the material and oxidative chemical reactions in the matrix are …

Mechanical and Thermal Characterization of Continuous Fiber-Reinforced Pyrolysis-Derived Carbon-Matrix Composites
<p>Maturity of high-temperature polymer-reinforced composites defer to conventionally expensive and intensive methods in both material and manufacturing aspects. Even traditional carbon-carbon, aerogel, and ceramic approaches are highly limited by difficult manufacturing techniques and are subject …

Ceramic coatings for silica and sapphire optical waveguides for high temperature embedding and sensing
… plastic coatings cannot withstand very high temperatures. In order to perform contact or invasive sensing in the medium to high temperature range and in harsh environments, other appropriate coating materials have to be used. This thesis examines various refractory materials as candidate …
