Claims100
A method of bonding a material to an article, the method comprising:
- longitudinally stretching a first tube of the material while heating the first tube and pressurizing an interior of the first tube, thereby forming a stretch blown tube of the material;
- and
- shrinking the stretch-blown tube of the material so that the material bonds to a surface of the article.
A device, comprising:
- an article having a surface;
- and
- a material bonded to the surface of the article,
- wherein the material has a post buckle fracture tensile strength of at least about 6500 psi.
A device, comprising:
- an article having a surface;
- and
- a material bonded to the surface of the article,
- wherein the material has a tensile strength of at least about 21,000 psi.
A device, comprising:
- an article having a surface;
- and
- a material bonded to the surface of the article,
- wherein the material has a hoop stress of at least about 3300 psi.
A device, comprising:
- an article having a surface;
- and
- a material bonded to the surface of the article,
- wherein the material has a load at break ratio of at least about 1.25.
A device, comprising:
- an article having a surface;
- and
- a material bonded to the surface of the article,
- wherein the material has a hoop stress ratio of at least about 1.25.
A tube-shaped article having a wall comprising a polymeric material having a post buckle fracture tensile strength of at least about 6500 psi.
A tube-shaped article having a wall comprising a polymeric material having a tensile strength of at least about 21,000 psi.
A tube-shaped article having a wall comprising a polymeric material having a hoop stress of at least about 3300 psi.
A tube-shaped article having a wall comprising a polymeric material having a load at break ratio of at least about 1.25.
A tube-shaped article having a wall comprising a polymeric material having a hoop stress ratio of at least about 1.25.
