Abstract: There is provided a process for preparing a prepreg (31) comprising reinforcement fibre (13) impregnated with a thermosetting resin matrix (20), said process comprising: a) providing a layer (24) of reinforcement fibre (13); b) applying a layer (24) of a first thermosetting resin matrix (20) to the first surface (15) of the layer (24) of reinforcement fibre (13) and bringing the first surface (15) of the layer (24) of reinforcement fibre (13) into contact with the support surface (5) of a first continuous belt (3), so that the layer (24) of first thermosetting resin matrix (20) is positioned between, and in contact with, the first surface (15) of the layer (24) of reinforcement fibre (13) and the support surface (5) of the first continuous belt (3); c) heating the layer (24) of first thermosetting resin matrix (20) applied to the first surface (15) of the layer (24) of reinforcement fibre (13) in contact with the support surface (5) of the first continuous belt (3); d) bringing the second surface (17) of the layer (24) of reinforcement fibre (13) into contact with the support surface 9) of a second continuous belt (7); e) heating the layer (24) of first thermosetting resin matrix (20) and the layer (24) of reinforcement fibre (13) between the support surfaces of the first and second continuous belts (3, 7) so that the first thermosetting resin matrix (20) impregnates the layer (24) of reinforcement fibre (13); f) cooling the layer (24) of reinforcement fibre (13) impregnated with the first thermosetting resin matrix (20) between the support surfaces of the first and second continuous belts (3, 7); and g) removing the layer (24) of reinforcement fibre (13) impregnated with the first thermosetting resin matrix (20) from the support surfaces of the first and second continuous belts (3, 7).

Abstract: Process for forming a permanent join between two sections of fibrous material contained in a thermosetting resin matrix, said process comprising overlaying the two sections and subjecting the overlaid sections to ultrasonic welding to form a permanent join between the two sections, wherein there is no significant change in the sub-ambient Tg of the fibrous material contained in the thermosetting resin matrix in the region of the permanent join.

Abstract: There is provide a process for unwinding material from a spool (2) wherein the angle (Θ) of take off at the first contact point (4) for the unwind is always in the range 0±20°, and wherein the first contact point (4) for the unwind is no more than 600 mm from the axis (3) of rotation of the spool (2). There is also provided an apparatus for the unwinding of material from a spool (2) comprising an axis (3) upon which a spool (2) may be rotatably mounted and a static first contact point (4) for the unwound material positioned no more than 600 mm from the centre of the axis (3), wherein the angle (Θ) of take off at the first contact point (4) for the unwind is always in the range 0±20°.
