摘要:
The present disclosure generally provides methods and apparatus for efficiently crosslinking silicon carbide fiber precursor polymers with electron beam radiation. The methods and apparatus utilize a platform containing silicon carbide fiber precursor polymer. The temperature of the platform is regulated while the silicon carbide fiber precursor polymer is irradiated to thereby regulate the temperature of the irradiated silicon carbide fiber precursor polymer thereon. In this way, the temperature of the irradiated silicon carbide fiber precursor polymer is regulated via the platform both during and after it is subjected to radiation. At least one of the platform and the e-beam radiation mechanism may be translated with respect to the other to irradiate different portions of the silicon carbide fiber precursor polymer and, ultimately, the entirety of the silicon carbide fiber precursor polymer contained on the platform.

The present disclosure generally relates to methods of using boron-containing additives for crosslinking polysilazane green fibers, which are precursors to silicon carbide fibers. These methods provide a controllable process for crosslinking silicon carbide fibers while providing a simple way for the introduction of boron as a sintering aid into the polymer structure.
摘要:
A system is provided for monitoring strain in a substrate using a strain sensor element within a fiber optic sensing cable. Accurate and rapid measurement of strain of remote substrates presents major technical challenges and is the focus of much of the description presented. However, systems, methods and devices provided by the present invention are not only capable of reliably measuring strain in real time, but are also capable of measuring other characteristics of a substrate such as its temperature, pressure and its acoustic characteristics. The system is configured such that a strain sensor element within a strain sensing zone detects substantially the true strain characteristics of the substrate. And while other sensing elements within the same fiber optic sensing cable may not be configured to detect substrate strain at all, these sensing elements may reliably measure the temperature and pressure at the surface of the substrate adjacent to the strain sensing zone.
