A gasket or gasket tape for interposition between a moveable aircraft workpiece and a stationary platform, the gasket comprising: a pliable, elastomeric gel body having an upper surface, a lower surface, and a perimeter; and a non-metallic, non-fibrous, electrically non-conductive, non-woven skeletal web having an upper surface, a lower surface, a perimeter and a multiplicity of intersecting strands meeting at and integral with a multiplicity of joints, the strands and joints defining a repeating pattern with a multiplicity of open pores; wherein the respective intersecting strands are integral to one another at respective ones of the plurality of joints; wherein the elastomeric gel body is as thick as or thicker than and substantially encapsulates the skeletal web, including filling the pores thereof; and wherein the x and y dimensions of the gel body are much greater than the z dimension, which is the thickness; and the elastomeric gel body is a tacky polyurethane gel and has a hardness between about 40-150 on 37.5 gr. half cone penetrometer; and wherein there is only a single layer of skeletal web and gel between the upper and lower surfaces of the elastomeric gel body and wherein the gasket or gasket tape is configured for lateral gel flow of said elastomeric gel body, when the gasket is under compression between the workpiece and base, such compression in the range of about 345 to 3450 kPa, wherein the skeletal web structure is resistant to such compression whereby such compression fails to cause permanent deformation of the thickness of the skeletal web of more than 5%; and wherein the skeletal web exhibits structural stability following compression at said compression range. a pliable, elastomeric gel body having an upper surface, a lower surface, and a perimeter; and a non-metallic, non-fibrous, electrically non-conductive, non-woven skeletal web having an upper surface, a lower surface, a perimeter and a multiplicity of intersecting strands meeting at and integral with a multiplicity of joints, the strands and joints defining a repeating pattern with a multiplicity of open pores; wherein the respective intersecting strands are integral to one another at respective ones of the plurality of joints; wherein the elastomeric gel body is as thick as or thicker than and substantially encapsulates the skeletal web, including filling the pores thereof; and wherein the x and y dimensions of the gel body are much greater than the z dimension, which is the thickness; and the elastomeric gel body is a tacky polyurethane gel and has a hardness between about 40-150 on 37.5 gr. half cone penetrometer; and wherein there is only a single layer of skeletal web and gel between the upper and lower surfaces of the elastomeric gel body and wherein the gasket or gasket tape is configured for lateral gel flow of said elastomeric gel body, when the gasket is under compression between the workpiece and base, such compression in the range of about 345 to 3450 kPa, wherein the skeletal web structure is resistant to such compression whereby such compression fails to cause permanent deformation of the thickness of the skeletal web of more than 5%; and wherein the skeletal web exhibits structural stability following compression at said compression range. wherein the elastomeric gel body is as thick as or thicker than and substantially encapsulates the skeletal web, including filling the pores thereof; and wherein the x and y dimensions of the gel body are much greater than the z dimension, which is the thickness; and the elastomeric gel body is a tacky polyurethane gel and has a hardness between about 40-150 on 37.5 gr. half cone penetrometer; and wherein there is only a single layer of skeletal web and gel between the upper and lower surfaces of the elastomeric gel body and wherein the gasket or gasket tape is configured for lateral gel flow of said elastomeric gel body, when the gasket is under compression between the workpiece and base, such compression in the range of about 345 to 3450 kPa, wherein the skeletal web structure is resistant to such compression whereby such compression fails to cause permanent deformation of the thickness of the skeletal web of more than 5%; and wherein the skeletal web exhibits structural stability following compression at said compression range.
