This invention relates to a kit for manufacturing a wind turbine blade component, a method of manufacturing such a wind turbine blade component and a wind turbine blade component thereof. The individual panel sections are interlocked via interlocking devices arranged between adjacent panel sections. The interlocking device comprises first engaging element for engaging the adjacent panel sections, wherein the interlocking device is forced into the panel section by applying force to the interlocking device.

A production device for a production of thermoset semifinished products comprises at least one material application unit (12) for applying a material (14) to a carrier element (16), wherein the production device further comprises at least one recording unit (18), which has at least one sensor element (20), for recording a thickness (22) of the material (14) applied to the carrier element (16).

An assembly for forming a gas turbine engine according to an example of the present disclosure includes, among other things, a layup tool including a main body extending along a longitudinal axis and a flange extending radially from the main body, the flange defining an edge face slopes towards the main body to an axial face. At least one compression tool has a tool body having a first tool section and a second tool section extending transversely from the first tool section. The first tool section is translatable along a retention member in a first direction substantially perpendicular to the edge face such that relative movement causes the second tool section to apply a first compressive force on a composite article trapped between the axial face of the flange and the second tool section. A method of forming a gas turbine engine component is also disclosed.

Compaction systems and methods of compacting components are provided. In one aspect, a laminate of a component can be laid up on a tool of a compaction system. The laminate defines a cavity. A noodle is positioned relative to or in the cavity. A noodle ring is then positioned relative to the noodle. For instance, the noodle ring can be placed over the noodle. A cross section of the noodle ring can be shaped complementary to a cross section of the noodle. A plunger of the compaction system is moved so that it engages the noodle ring. Particularly, the plunger is moved in such a way that a force is applied on the noodle ring so that the noodle ring compacts the noodle into the cavity.

A molding jig for molding a laminate, which includes reinforced fiber sheets laminated on each other, extends in the length direction, and has a cross-sectional shape having a curved portion in a cross section obtained by cutting the laminate on a plane orthogonal to the length direction, into a three-dimensional shape having a bent portion in the length direction. The molding jig includes a female die for forming the bent portion, a male die for engaging with the female die with the laminate therebetween for forming the bent portion, and a stretchable supporting member between the female die and the laminate. The laminate comes in contact with the male die on both length-direction sides of the molded bent portion, and the supporting member is over a region including the female-side molding surface.

A carrier film set configured to apply a number of stiffener assemblies to a layup mandrel, the carrier film set comprising: a number of alignment features configured to align the carrier film set relative to the layup mandrel; and a number of indexing features configured to index the number of stiffener assemblies onto the carrier film set.

A system for manufacturing a composite part including a conductive flexible facesheet and an automated tape layup (ATL) machine for laying up composite tape onto the facesheet that is laid flat on a flat surface. The system also includes a curved tooling surface for transferring the facesheet with the composite material thereon to the curved tooling surface for attachment of substructures and curing into the composite part. System may also include insulation placed below the facesheet and insulation placed above the composite material, as well as a source of electricity and heat for heating the conductive facesheet to cure, melt, or fuse the composite tape and substructures without heating the tooling surface and other tooling used in the composite curing process. Heating of the facesheet may be performed using joule heat provided by a single turn transformer inducing current to conductive wires attached at opposing ends to the facesheet.

Described are methods and systems for identifying processing locations in composite layups. An optical magnetic marker is magnetically supported by a layup tool at a target position, such that a portion of the marker protrudes above the tool processing surface. When a composite layup is placed onto that surface, the protruding portion extends into the layup at a processing location. When the layup is cured, the marker is permanently embedded into the layup. Separating the cured layup from the tool removes the marker from the tool and allows an additional marker to advance into the target position for processing another layup. The embedded marker or, more specifically, marker's reflective surface is used during optical inspection of the layup surface to precisely determine the processing location. In some examples, the marker is consumed while the layup is processed at that location,

A mold assembly for manufacturing a composite part with a stiffener, the mold assembly includes a bottom mold configured to form a first surface of the composite part, wherein the bottom mold has at least one elongated recess configured to form a stiffener in the composite part; a feeder unit having a shape corresponding to the at least one elongated recess, wherein the feeder unit is configured to fit at least partially into the at least one elongated recess; and a top mold configured to form a second surface of the composite part opposite to the first surface. Also a method of manufacturing a composite part using such a mold assembly, which includes draping a flat laminate over the bottom mold and pushing portions of the laminate into the at least one elongated recess.

A composite forming apparatus includes an end effector and a forming feature that is coupled to the end effector. The end effector moves the forming feature relative to a forming tool to form a composite ply over a forming surface of the forming tool or over previously formed composite material on the forming surface of the forming tool. The composite forming apparatus further includes a positioning member engaged with the forming feature. The engagement between the positioning member and the forming feature facilitates a position between the forming feature and the composite ply to promote uniform application of compaction force over the forming surface of the forming tool.
