Abstract: According to the present invention, there is provided a pipe forming apparatus for forming a pipe at an installation site. The apparatus includes a former upon which material is wound, and a mold for receiving the former bearing the wound material. An applicator is provided for applying curable liquid within the mold. Advantageously, the pipe is formed at site to provide for efficient formation of a pipeline. A transported ISO container providing the material and curable liquid to the site can produce 800 metres of pipeline section, compared with 60 metres in the prior art, representing a significant increase in efficiency.

Abstract: A semi-finished product for the manufacture of a structural component has a plurality of prepreg tapes, each having unidirectionally arranged reinforcing fibers embedded in a thermoplastic matrix material, and with a plurality of connecting strands containing a thermoplastic material. The prepreg tapes and the connecting strands are either joined to form a textile sheet structure or the prepreg tapes are arranged to form a multiaxial fabric, individual layers of the fabric being joined by the connecting strands. Further, a method for manufacturing a curved structural component from such a semi-finished product is described.

Abstract: A system for manufacturing a part includes a mold having a contoured forming surface. The system also includes at least one tension strap, configured to attach to a consolidated laminate sheet, and a heating assembly, positioned relative to the mold and configured to supply heat to the consolidated laminate sheet, when attached to the at least one tension strap, to form a heated consolidated laminate sheet. The system additionally includes a strap retraction mechanism, configured to retract the at least one tension strap, when attached to the consolidated laminate sheet, to force the heated consolidated laminate sheet against the contoured forming surface of the mold. The heating assembly includes a flexible heating element configured to flex to conform to a shape of the heated consolidated laminate sheet as the heated consolidated laminate sheet is forced against the contoured forming surface of the mold.

Abstract: A shape forming tool for pre-carbonization compression of a fibrous preform is provided, comprising a female forming tool, a first plug, a second plug, and a wedge, each configured to be received by a die recess of the female forming tool. A first tapered surface of the wedge is configured to engage the first plug and the second tapered surface of the wedge is configured to engage the second plug. In response to the first tapered surface of the wedge engaging the first plug and the second tapered surface of the wedge engaging the second plug, the first plug and the second plug, respectively, are configured to move laterally towards opposing sides of the female forming tool and/or vertically toward a bottom side of the female forming tool to compress the fibrous preform into a shaped body.

Abstract: A tooling set for stamp forming a workpiece includes a first stamping tool, a second stamping tool and an elastomeric layer between the first and second stamping tools. The first stamping tool defines a first forming face. The second stamping tool defines a second forming face. The elastomeric layer defines first and second compliant stamping surfaces. A method for stamp forming a workpiece includes positioning a workpiece between the first stamping tool and the elastomeric layer and compressing the workpiece between the first forming face and the first compliant stamping surface in response to the first and second stamping tools being approximated. A system for stamp forming a workpiece includes the tooling set.

Abstract: The present application relates to a composite material and a method for molding the same. Firstly, components to be pressed is disposed in a gas-isolation element, and located between two pressing plates. Next, a plate is disposed based on a location of a prepreg element of the components, and then a hot pressing step is performed. After the hot pressing step, a cooling step is performed, thereby producing the composite material of the present application. A dimension of the composite material can be easily adjusted to meet requirements of various applications.

Abstract: Moulding a composite pipe of fibre reinforcement material and a thermosetting resin that shrinks upon curing includes wrapping fibre reinforcement material about the tubular resilient sleeve of a mandrel in a non-expanded state of the sleeve. The mandrel includes an internal support structure for the sleeve which is reversibly expandable in diameter between the non-expanded state. The sleeve is internally supported by the internal support structure and an expanded state by application of an internal pressure to the sleeve. The mandrel with the fibre reinforcement material wrapped about the sleeve is accommodated in a bore of a mould. Seal members provide a closed annulus that can be evacuated. A thermosetting resin that shrinks upon curing is introduced into the closed annulus. A pressurizing fluid is supplied to the mandrel to internally pressurize the sleeve to cause diametrical expansion into the expanded state thereof whilst curing of the thermosetting resin.
