Abstract
A sealing material comprises a partially or fully cured polysulphide sealant and a reinforcing element, especially glass fibre. The sealing material is a flexible solid and is preferably in sheet form. The sealing material is cut to shape like a gasket and is assembled between components to be fastened, for example, in airframe manufacture.
Claims18
A joint for joining two components in an aircraft, the joint including
- a fastener, and
- a sealing material in the form of a sheet comprising a cured polysulphide sealant and a reinforcing element which restricts the movement of the sealing material under pressure induced by the tightening of a fastener, the sealing material disposed so that the fastener passes through the sheet such that a significant thickness of the sealing material remains between the two components, after the fastener has been tightened, said reinforcing element selected from the group consisting of fibre materials and mesh materials.
A sealing material for use in sealing joints in aircraft, the sealing material being in the form of a sheet comprising
- an at least partially-cured polysulphide sealant, and
- a reinforcing element which restricts the movement of the sealing material under pressure induced by the tightening of a fastener wherein said fastener passes through the sealing material, such that a significant thickness of the sheet sealing material remains between two components, after the fastener has been tightened, said reinforcing element selected from the group consisting of fibre materials and mesh materials.
A joint for joining two components in an aircraft, the joint including
- a fastener, and
- a sealing material comprising an essentially fully cured polysulphide sealant such that it has a Shore A hardness of at least 35° A, and a woven fibre reinforcing element which restricts the movement of the sealing material under pressure induced by the tightening of a fastener, said fastener passing through the sealing material such that a significant thickness of the sealing material remains between the two components, after the fastener has been tightened.
