There is disclosed an apparatus for winding filaments to form a structure. The apparatus includes a carrier which mounts spools of fiber, a mandrel, and a guide element which directs fiber tows, comprising filaments from the spools, onto the mandrel. The system further includes a heating element which applies heat to the fiber tows, and a diaphragm element which defines an orifice about the mandrel. The diaphragm element includes one or more displaceable portions which define a physical dimension of the orifice and which: displace to vary the physical dimension of the orifice; and apply a predetermined pressure to the fiber tows disposed on the mandrel. Also disclosed and described is a related method.

System for in-situ consolidation and curing of composite structures

An optical signal source is positioned at a first side of the flow cell or the flow-line bypass. The optical signal source is capable of emitting an optical signal through the first side of the flow cell or the flow-line bypass. A first optical detector is positioned at a second side of the flow cell. The second side is opposite the first side. The first optical detector is capable of detecting a transmitted-light intensity of the optical signal transmitted through the second side of the flow cell or the flow-line bypass. A second optical detector is positioned at a third side of the flow cell. The third side is different than the first side and the second side. The second optical detector is capable of detecting a scattered-light intensity of a scattered optical signal transmitted through the third side of the flow cell or the flow-line bypass.
