Abstract
Provided is a method of forming a thru-hole through a composite structure having a plurality of internal compartments. An insert ring is connected to the composite structure to create a protective layer around the periphery of a penetration formed within the composite structure. An adhesive is disposed between the composite structure and the insert ring to create a fluid-tight seal between the insert ring and the internal compartments. In this regard, the fluid-tight seal mitigates fluid flow between the internal compartments.
Claims22
A method of forming a thru-hole to allow wiring or mechanical components to pass through a structure having a first exterior surface, an opposing second exterior surface, a plurality of horizontally oriented, vertically layered internal fluid storage compartments disposed between the first exterior surface and the second exterior surface and a penetration wall defining an internal diameter extending through the structure between the first exterior surface and the second exterior surface to define a penetration, the method comprising the steps of:
- a) providing an insert ring including a male portion and a separate female portion, the male portion having a male ring and a male flange extending radially outward from the male ring, the female portion having a female ring and a female flange extending radially outward from the female ring, the female ring and male ring being cooperatively engageable to define a cylindrical aperture;
- b) lining the penetration wall with adhesive;
- c) locating the female portion proximate the first exterior surface, while inserting the female ring into the penetration;
- d) locating the male portion proximate the second exterior surface, while inserting the male ring into the penetration;
- e) engaging the male and female portions within the structure, the male portion and the female portion being brought into compressive engagement with the structure, such that the cylindrical aperture extends through the penetration to define the cylindrical aperture extending though the structure after the male and female portions are brought into compressive engagement, the adhesive being disposed between the insert ring and the structure to couple the insert ring thereto and to create a fluid tight seal between the plurality of internal compartments, and between the plurality of internal compartments and the insert ring;
- and
- f) upon completion of step e), passing wiring through the cylindrical aperture.
A method of forming a thru-hole to allow wiring or mechanical components to pass through a multilayer structure having a first exterior surface, an opposing second exterior surface, a plurality of horizontally oriented, vertically layered internal fluid storage compartments disposed between the first exterior surface and the second exterior surface, and a penetration wall defining an internal diameter extending through the structure between the first exterior surface and the second exterior surface to define a penetration, the method comprising the steps of:
- a) providing an insert ring including a male portion and a female portion, the male portion having a male ring and a male flange extending radially outward from the male ring, the female portion having a female ring and a female flange extending radially outward from the female ring, the female ring and male ring being cooperatively engageable to define a substantially cylindrical aperture extending between the first and second exterior surfaces after the male ring and female ring are engaged;
- b) lining the entire penetration wall with adhesive;
- c) separately extending the male portion and the female portion into the structure penetration, from the first and second surfaces, respectively, after the entire penetration wall is lined;
- d) engaging the male and female portions within the structure, at least one of the male portion and the female portion being in sealing compressive engagement with an adjacent and exterior structure surface, the adhesive being urged into the structure internal compartments to create a fluid tight seal between the plurality of internal compartments, and between the insert ring and the structure to couple the insert ring thereto;
- and
- e) upon completion step d), passing wiring through the cylindrical aperture.
