A bonded composite joint includes a first carbon fiber-reinforced polymer (CFRP) panel; a second CFRP panel; a corrugated structure placed between the first and second CFRP panels; and an adhesive placed between the first and second CFRP panels and in contact with the corrugated structure. The corrugated structure has a shape defined by a given wavelength λ.

A CFRP material with an Al alloy sheet attached to or a CFRTP material with an Al alloy sheet attached to is prepared by joining an Al alloy sheet with a CFRP material or a CFRTP material by adhesion or by injection molding. The surface of this Al alloy sheet and a surface of metal material such as Ti, etc., are subjected to chemical treatment. After this chemical treatment, the CFRP material with an Al alloy sheet attached to or the CFRTP material with an Al alloy sheet attached to and the metal material are inserted into a metallic mold for injection molding so as to have a gap therebetween. High crystalline thermoplastic resin is injected into this gap to join the metal material with the Al alloy sheet, thus obtaining a laminated composite.

Apparatuses, methods, and systems are disclosed for an adhesive including an activated portion and an unactivated portion. The adhesive is interposed between and binds the first substrate to a second substrate. The unactivated portion includes moisture, and the activated portion is activated to adhere in response to the removal of moisture. Similarly, the unactivated portion of the adhesive may be activated in response to the removal of moisture, removal of air, applying radiation, heating, and/or catalyzing a functional group.

A method for manufacturing a smart card capable of achieving excellent connection reliability and bending resistance, a smart card, and a conductive particle-containing hot-melt adhesive sheet. A conductive particle-containing hot-melt adhesive sheet containing solder particles of a non-eutectic alloy in a binder containing a crystalline polyamide having a carboxyl group is interposed between a card member and an IC chip and subjected to thermocompression bonding. The crystalline polyamide having a carboxyl group improves the solder wettability of the non-eutectic alloy, thereby achieving excellent connection reliability. This effect is considered to be a flux effect due to the carboxyl group present in the crystalline polyamide, and as a result, it is possible to prevent the decrease in the elastic modulus of the adhesive layer which would be caused by the addition of a flux compound and to achieve excellent bending resistance.

Improvements relating to wind turbine blade manufacture 5 A method of making a wind turbine blade is described. The method involves providing a blade shell having an inner surface defining a mounting region and positioning a web in the mounting region. One or more web restraining devices are used to secure the position of the web in the mounting region. Each restraining device has a first portion attached to the web and a second portion attached to the inner surface of the blade shell. The 10 restraining devices are configured to prevent movement of the web in a first plane substantially parallel to the mounting region and to permit movement of the web in a second plane substantially perpendicular to the mounting region. The method further comprises moving the web in the second plane away from the mounting region and performing one or more preparatory operations on the mounting region with the web 15 moved away from the mounting region. The web is then repositioned in the mounting region by moving the web in the second plane back towards the mounting region.

A method and a system are provided for retaining a side window in a vehicle to meet FMVSS No. 226 standard, where the side window is being secured to an exterior surface of a vehicle body. An optically transparent flexible film laminate is adhered to a visible interior surface of the side window. The optically transparent flexible film laminate has a thickness of between about 0.005 inches and about 0.020 inches. A peripheral edge of the optically transparent flexible film laminate is bonded to an interior surface of the vehicle body. The bonding agent overlaps the peripheral edge and the interior surface at a distance of at least 0.5 inches. The bonding agent can be a Sikaflex-552 adhesive.
