Abstract
A fire seal end cap including a cap portion and a plug portion, wherein the plug portion protrudes from the cap portion, and wherein the cap portion and the plug portion are formed from a fire-resistant material.
Claims20
A fire seal end cap comprising:
- a cap portion defining a first major surface;
- and
- a plug portion having a curved rear end and a flat forward end, the plug portion protruding from said cap portion along a protrusion direction, the curved rear end corresponding to a contour of a bore for receiving the plug portion,
- wherein said cap portion and said plug portion are formed from a fire-resistant material;
- wherein said fire-resistant material is a composite material comprising a woven ceramic fabric infused with a matrix material comprising silicone;
- wherein said composite material further comprises a low friction material having a static coefficient of friction of at most 0.15;
- wherein a cross-section of said plug portion normal to said protrusion direction is D-shaped and
- wherein said protrusion direction is at a non-zero angle between 1 and 20 degrees of normal to said first major surface.
5 more elements
A multi-member assembly comprising:
- a first structural member;
- a second structural member opposed from, and moveable relative to, said first structural member;
- a crossover seal that comprises a body elongated to extend in a lateral direction positioned between said first structural member and said second structural member, said crossover seal defining a bore;
- and
- a fire seal end cap comprising:
- a cap portion defining a first major surface;
- and
- a plug portion protruding from said cap portion along a protrusion direction either normal to said major surface, or at a non-zero angle between 1 and 20 degrees of normal to said major surface, positioned such that said plug portion protrudes into said bore and said cap portion overlaps both said first structural member and said second structural member,
- wherein the plug portion has a curved rear end that corresponds to a contour of the bore of the crossover seal,
- wherein said lateral direction and said protrusion direction are parallel or coincide, and
- wherein a gap is defined between the crossover seal and the plug portion.
8 more elements
A fire seal end cap comprising:
- a rectilinear cap portion defining a first major surface;
- a plug portion protruding from said cap portion along a protrusion direction either:
- a) normal to said first major surface, or
- b) at a non-zero angle between 1 and 20 degrees of normal to said first major surface;
- wherein said cap portion and said plug portion are formed from a fire-resistant material;
- wherein a cross-section of said plug portion normal to said protrusion direction is D-shaped and comprises a forward end and a rear end, wherein said forward end is substantially flat, and wherein said rear end corresponds to a contour of a bore for receiving the plug portion.
