Claims
- 1. Apparatus for producing a ceramic composite panel comprising:
- a) apparatus for positioning a pair of fiber reinforced ceramic matrix composite panels in spaced relationship;
- b) apparatus for injecting a mixture of a liquid pre-ceramic resin and a liquid phenolic resin between said pair of panels so that the resultant mixture chemically foams and sets in an entire space between said panels to form a composite panel; and,
- c) apparatus for heating said composite panel within an inert environment for a time and at a temperature which converts said pre-ceramic resin to a ceramic and out-gasses said phenolic resin.
- 2. Apparatus for producing a ceramic composite panel comprising:
- a) apparatus for positioning a pair of fiber reinforced ceramic matrix composite panels in spaced relationship;
- b) apparatus for creating a foam from a pre-ceramic resin filling the entirety of a space between said pair of panels; and,
- c) apparatus for heating said foam for a time and at a temperature which converts said pre-ceramic resin to a ceramic.
- 3. The apparatus of claim 2 and additionally comprising:
- a) apparatus for injecting a mixture of a liquid pre-ceramic resin and a liquid phenolic resin in a space between said pair of panels;
- b) means for allowing said mixture to chemically foam and set in the entirety of said space between the panels to form a composite panel; and,
- c) apparatus for heating said composite panel for a time and at a temperature which converts said pre-ceramic resin to a ceramic and out-gasses said phenolic resin.
- 4. Apparatus for producing a ceramic composite panel comprising:
- a) a supply of a first fibrous web;
- b) apparatus for saturating said first web with a liquid pre-ceramic resin;
- c) apparatus for depositing a mixture of a liquid pre-ceramic resin and a liquid phenolic resin on said first web;
- d) means for allowing the resultant mixture to chemically foam and expand into a foam layer;
- e) a supply of a second fibrous web of said generic fiber system;
- f) apparatus for saturating said second web with a liquid pre-ceramic resin;
- g) apparatus for depositing said second web on said foam layer while compressing said foam layer to a desired thickness to form a composite panel; and,
- h) apparatus for heating said composite panel within an inert environment for a time and at a temperature which converts said pre-ceramic resin to a ceramic and out-gasses said phenolic resin.
