US Patent:

20190145027, May 16, 2019

Filed:

Jan 16, 2019

Appl. No.:

16/249433

Inventors:

- Chicago IL, US
Tiffany A. Stewart - Sherman Oaks CA, US
Bruce Huffa - Encino CA, US

International Classification:

D02G 3/44
D06C 7/02
D04B 1/14

Abstract:

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape performs at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

US Classification:

181285

Abstract:

An acoustic barrier structure can include a support structure that defines a plurality of cells, a weight attached to the support structure, and at least one resonant membrane covering one of the plurality of cells. The at least one resonant membrane can comprise at least one weight. The at least one resonant membrane can have an anti-resonant frequency and the support structure with the weight can provide wide frequency band gaps between odd resonance modes while suppressing structure-membrane coupled modes to enable the anti-resonance of the at least one resonant membrane.
