Conversion of silicon to silicon carbide for ceramic matrix composite fabrication
Techniques and methods for producing silicon carbide and ceramic matrix composites from hydrocarbons are disclosed. In one aspect, the method includes performing into a shape using silicon carbide fibers placed in a chamber, evacuating the chamber causing silicon and polymer slurries to enter the chamber, and pressurizing the chamber causing the silicon and polymer slurries to permeate the silicon carbide fibers. The method includes heating the chamber to cause pyrolysis of the polymer and hydrocarbon transferred into the chamber to carbon and hydrogen. The carbon from pyrolyzing the polymer and hydrocarbon provides a carbon coating on the silicon in the silicon and polymer slurry. The method includes heating the chamber to a higher temperature causing silicon to melt and react with carbon to form silicon carbide. The formed silicon carbide and silicon carbide fibers form a ceramic matrix composite material.
公开了用于由烃产生碳化硅和陶瓷基体复合材料的技术和方法。在一个方面，该方法包括使用放置于室中的碳化硅纤维预成型为一定形状，抽空室导致硅和聚合物浆料进入室，以及对室进行加压，导致硅和聚合物浆料渗透碳化硅纤维。该方法包括加热室，以导致传送到室中的聚合物和烃热解成碳和氢气。来自热解聚合物和烃的碳在硅和聚合物浆料中的硅上提供碳涂层。该方法包括将室加热到较高温度，导致硅熔融并与碳反应形成碳化硅。所形成的碳化硅和碳化硅纤维形成陶瓷基体复合材料。
