    摘要： A method for manufacturing a fiber-containing element, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 98 wt % of the total weight of starting materials in the form of a collected web, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, subjecting the collected web of fibers to a disentanglement process, suspending the fibers in a primary air flow, mixing the binder with the fibers before, during or after the disentanglement process, providing a filler, such as a fire retardant, in an amount of 1 to 55 wt % of the total weight of starting materials, adding the filler at any suitable step of the method, such as before, during or after the disentanglement process, collecting the mixture of fibers, filler and binder and pressing and curing the mixture to provide a consolidated composite with a density of from 120 kg/m3 to 1000 kg/m3. With this method homogeneous composites can be produced.

    摘要： 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.
