Abstract
A process for providing pores in a structure according to any selected physical characteristics. Generally pins or pore forming members may be positioned in a laminate preform and the laminate preform formed into a laminate structure including the pins therein. The pins generally include a size, density, distribution, angle, or other characteristic that is desired in the final laminate structure. After the laminate is formed the pins are then removed from the laminate according to a process which does not harm a selected physical characteristics of the laminate structure.
Claims19
A method for forming a laminate material including a selected pore, comprising:
- selecting a substantially oxide-free fabric;
- forming a fabric stack including at least one layer of said selected substantially oxide-free fabric to be laminated into a substantially coherent laminate structure;
- placing a pin into the fabric stack, said pin having a selected profile such that said selected pore remaining in said laminated structure allows for substantially uni-directional flow of a flowable material through the laminated structure;
- laminating the fabric stack such that the fabric stack becomes laminated into a laminated structure;
- removing the pin from the laminated structure to form a substantially selected pore in the laminated structure;
- and
- cooling a structure with said uni-directional flow of said flowable material through said laminated structure.
A method of forming with a laminated panel having a plurality of uni-directional pores, comprising:
- forming a laminate preform including a plurality of layers of material;
- disposing a plurality of pore forming members in said laminate preform in a selected pattern;
- processing said laminate preform to form a laminated structure;
- and
- abolishing the pore-forming members in the laminated structure to form a plurality of uni-directional pores in said laminated structure that have a selected profile to enable uni-directional flow of a flowable material through said laminated structure.
A method for forming a structure including a substantially selected porosily comprising:
- forming a laminate preform including a plurality of layers of material;
- disposing a member at least partially through said laminate preform;
- processing said laminate preform with said member disposed in said laminate preform to form a substantially laminated structure;
- destroying the member in said laminated structure to form a plurality of pores in said laminated structure, said destroying of the member being accomplished with at least one of substantially little oxidation and degradation to the laminated materials;
- disposing said laminated structure adjacent to a structure;
- and
- cooling said structure through said pores formed in said laminated structure;
- wherein disposing a member through said laminate preform includes:
- positioning the member through said layers of material in a selected manner;
- wherein disposing a member through said laminate preform includes:
- selecting a member having a desired profile such that a pore left in said laminated structure by said member creates a substantially uni-directional flow of a flowable material.
