A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

A bonding apparatus includes a first holder, a first transforming device, a second holder, a second transforming device, a suction device and a control device. The first holder attracts and holds a first substrate from above. The first transforming device transforms the first substrate held by the first holder such that a central portion of the first substrate is protruded downwards. The second holder is provided under the first holder, and attracts and holds a second substrate, which is to be bonded to the first substrate, from below. The second transforming device transforms the second substrate held by the second holder such that a central portion of the second substrate is protruded upwards. The suction device generates different attracting forces in multiple division regions included in an attraction region of the second substrate. The control device controls the suction device.

A method of making an array of vapor cells for an array of magnetometers includes providing a plurality of separate vapor cell elements, each vapor cell element including at least one vapor cell; arranging the vapor cell elements in an alignment jig to produce a selected arrangement of the vapor cells; attaching at least one alignment-maintaining film onto the vapor cell elements in the alignment jig; transferring the vapor cells elements and the at least one alignment-maintaining film from the alignment jig to a mold; injecting a bonding material into the mold and between the vapor cell elements to bond the vapor cell elements in the selected arrangement; removing the at least one alignment maintaining film from the vapor cell elements; and removing the bonded vapor cells elements in the selected arrangement from the mold to provide the array of vapor.

The present invention relates to a wind turbine blade and a method for its manufacture. A lower shell part and an upper shell part are provided, each shell part having a leading edge and a trailing edge. A first shear web and a second shear web for connecting an inner surface of the lower shell part with an inner surface of the upper shell part are provided. The first shear web and the second shear web are connected by a first distance member in a chordwise direction. The first distance member is arranged for accommodating a variable chordwise distance between said first shear web and said second shear web. The first shear web and the second shear web are placed in the lower shell part and the upper shell part is mounted.

A method of making a wind turbine blade (10) having a shear web (20, 22) bonded between first and second half shells (16, 18) is described. The method involves providing a web locator (40) on an inner surface of a half shell. The web locator has a fixed portion (42) and a spring portion (44) extending from the fixed portion. The spring portion is moveable relative to the fixed portion between compressed and relaxed states.

A method of arranging, in particular thermoplastic, semi-finished products by using an electronically controlled or regulated placing device for the semi-finished products. The method includes detecting at least one part of an outline of a semi-finished product to be placed, wherein the detecting is carried out by a detection device, determining a target position for the semi-finished product and/or for the placing device for placing the semi-finished product by matching the at least one part of the outline with a placing edge occurring on an underlying surface, and placing the semi-finished product by the placing device using the target position.

A method of making a modular wind turbine blade is described. The modular blade comprises first and second blade modules connected together by a scarf joint between tapered spar caps of the respective blade modules. According to the method, first and second blade modules are laid up in the same mould assembly. A separating layer is arranged between the layups of the first and second module in a joint region of the mould. The separating layer has a thickness corresponding to a required bond thickness in the scarf joint when the modules are bonded together.

Systems and methods are provided for designing composite parts. One embodiment is a method for fabricating a composite part. The method includes receiving a design that defines a stacking sequence for a composite charge comprising plies that have different fiber orientations, defining a splice zone within the design, modifying the design by splicing plies in a manner that accommodates ply slippage when the composite charge is formed to a contour, and fabricating a composite part based on the design that was modified.

A sheet space-detecting device detects a space between a rear end of a preceding first fiber reinforced plastic sheet and a front end of a following second fiber reinforced plastic sheet in a conveyance path for fiber reinforced plastic sheets and includes: a light-detecting sensor that projects detection light on an area including the rear end of the first fiber reinforced plastic sheet, the front end of the second fiber reinforced plastic sheet, and a reference surface exposed from the space and receives reflected light thereof; and a spacer that supports the rear end of the first fiber reinforced plastic sheet and the front end of the second fiber reinforced plastic sheet in a state where the rear end and the front end are separated from the reference surface, in an area including at least a light-projected area on which the detection light is projected.
