Claims5
A composite structure comprising:
- a plurality of components coupled together forming a joint, wherein said plurality of components are oriented such that a gap is defined at least partially therebetween;
- wherein said plurality of components are coupled together such that said gap extends along a length of said plurality of components;
- wherein at least one of said plurality of components comprises a bent portion such that a radius gap is defined between said plurality of components;
- and
- a filler structure positioned in said gap, said filler structure comprising a closed cell foam core having a porosity within a range defined between about 20 percent and about 40 percent by volume of said closed cell foam core, and said filler structure pre-formed and having a cross-sectional shape substantially similar to a cross-sectional shape of said gap;
- and wherein said closed cell foam core is fabricated from a silicone-based material.
