摘要： A technical problem to be solved by the present invention is to provide a non-coated fabric for airbags and a coated fabric for airbags that are both less likely to have yarn slippage after being sewn, and that can be compactly stored; and airbags using these fabrics. The fabric for airbags according to the present invention is a non-coated fabric for airbags or a coated fabric for airbags that both have a crimp ratio of 12% or more in the warp direction, and a crimp ratio of 61 or less in the weft direction.

摘要： A method of preparing a fibrous preform for use in a ceramic matrix composite comprises coiling a serving yarn around a ceramic tow to form a served tow, the serving yarn comprising a polymer material with embedded ceramic particles, incorporating the served tow into a woven fabric, the woven fabric comprising a plurality of served tows, and removing the polymer material of the serving yarn such that the embedded ceramic particles remain in the woven fabric.
