Abstract
Official abstract text for this publication.
A sheet containing a carbon fiber and a fluororesin layer disposed around a carbon monofilament constituting the carbon fiber. A fluororesin constituting the fluororesin layer is polyvinylidene fluoride. Further, the sheet has a tensile strength of 400 MPa or higher. Also disclosed is a laminate including a first layer and a second layer that is disposed on the first layer and that includes the sheet; a pipe including the laminate; a riser tube including the pipe and a flowline including the pipe.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sheet comprising: a carbon fiber having an average fiber length of 50 mm or longer; and a fluororesin layer disposed around a carbon monofilament constituting the carbon fiber, a fluororesin constituting the fluororesin layer being polyvinylidene fluoride, the sheet having a tensile strength of 400 MPa or higher and a tensile modulus of 15000 MPa or higher. 2. The sheet according to claim 1 , wherein the polyvinylidene fluoride is a homopolymer of vinylidene fluoride. 3. The sheet according to claim 1 , wherein the sheet is a tape. 4. A laminate comprising: a first layer; and a second layer that is disposed on the first layer and that includes the sheet according to claim 1 . 5. A pipe comprising the laminate according to claim 4 . 6. The pipe according to claim 5 , wherein the first layer is a flexible tube. 7. A riser tube comprising the pipe according to claim 5 . 8. A flowline comprising the pipe according to claim 5 . 9. A pipe comprising: a first layer; and a second layer that is disposed on the first layer and that includes the sheet according to claim 3 , the first layer and the second layer being stacked in the given order from an inner side of the pipe, the second layer being formed from the tape wrapped around an outer surface of the first layer.
