Manufacturing method for ceramic matrix composite

A manufacturing method for a ceramic matrix composite, having a woven fabric that has multiple fiber bundles and having a matrix that is disposed in the gaps between the fiber bundles, includes: a green body formation step for forming a green body by sintering the woven fabric infiltrated with a polymer that is a precursor to the matrix; and a densification step for further infiltrating the green body with a polymer and sintering same. The densification step includes: a second infiltration step for further infiltrating the green body with a polymer so as to form an infiltrated green body; a drying step for drying the infiltrated green body so as to form a dried green body; a steam treatment step for leaving the dried green body under saturation water vapor pressure so as to form a treated green body; and a sintering step for sintering the treated green body.

Multifunctional high-strength composite fabric coating agent, coating, method for preparing the same, and application thereof

A multifunctional high-strength composite fabric coating agent, a coating, a method for preparing the same and an application thereof are provided. The fabric coating agent includes a resin, a reinforcing agent with a reactive group, a bifunctional dispersing agent, a leveling agent, a film forming agent, a softening agent, an antibacterial agent, a solvent, and the like. The reinforcing agent is modified such that it has active functional groups of —OH and NH.sub.3. The fabric coating agent is not only easy to apply, fast to react and stabilize, but also suitable for a fabric surface of any material. A treated fabric has high tensile-breaking strength, excellent tearing and bursting performance, good waterproof-and-moisture-permeability and antibacterial performance, and high adhesion. It can be repeatedly knife coated, roll coated, calendared, or dipped. The method is not only mature in technology and low in production cost, but also suitable for large-scale application.
