| 摘要 |
<p>The invention provides a method for making a pipe section comprising; providing a mat (1) formed of a fibre matrix impregnated with an aerogel, xerogel or cryogel, the mat having a first major face (2), a second major face (3) opposing the first major face (2), a first edge (4) defining a longitudinal direction, a second edge (5) substantially parallel to the first edge (6), a third edge defining a transverse direction that is substantially perpendicular to the longitudinal direction and a fourth edge (7) substantially parallel to the third edge; applying an adhesive (8) to the first major face; winding the mat around a mandrel (13) to provide a wound mat having an inner surface (11) defining an inner circumference and an outer surface (12) defining an outer circumference and a longitudinal axis which is substantially perpendicular to the planes of the inner and outer circumferences and substantially parallel to the transverse direction of the mat; and slicing the wound mat substantially radially between the outer surface and the inner surface to provide a cut extending in a direction substantially parallel to the longitudinal axis.</p> |
