20210308956 · 2021-10-07 ·

A joining method and assembly for an aircraft. To improve the characteristics or permit hitherto impossible connections between thermoplastic and thermoset components, a multi-material joining method is disclosed in which a thermoplastic connecting region is formed on the thermoplastic component. The connecting region is connected to the thermoset component by interdiffusion. For this purpose, the uncured second component is brought into contact with the connecting region and heat is supplied. An interdiffusion layer is formed which fixedly connects the second component and the connecting region to one another and thus joins the first component to the second component.

The base element consists of a thermoplastic with a temperature of continued use of at least 130° C., which can be poorly irradiated or cannot be irradiated with light, and has at least one irradiation region. The base element can be irradiated with light in this region in such a way that light energy penetrates the base element. The irradiation region, in cross-section, has a smaller thickness and a transmittance at least 20% with a light wavelength between 320 and 500 nm. Alternatively, the irradiation region is formed by a through-opening.

A first sheet layer made of a nonwoven fabric; a second sheet layer made of a nonwoven fabric opposed to one side of the first sheet layer; and a plurality of elongated elastically stretchable members provided along the stretchable direction at intervals from each other between the first sheet layer and the second sheet layer are provided. At least a part of each end of the elastically stretchable member is fixed to at least one of the first sheet layer and the second sheet layer only via a first hot melt adhesive. The first sheet layer and the second sheet layer are bonded via a second hot melt adhesive in a range in the stretchable direction corresponding to a space between the both ends of the elastically stretchable member. The holding power of the first hot melt adhesive is higher than the second hot meld adhesive.

ADHESIVE APPLICATION APPARATUS

There is provided an adhesive application apparatus capable of efficiently applying an adhesive without inhibiting curing of the adhesive. An adhesive application apparatus of the present invention includes a mounting table 10, an adhesive dosing unit 20, and an ultraviolet irradiation unit 30, and it applies a delayed-ultraviolet-curable adhesive 200 to a surface of a panel 100. The panel 100 is mounted on a mounting surface S10 of the mounting table 10. The adhesive dosing unit 20 applies the adhesive 200 to the surface of the panel 100 mounted on the mounting table 10 by discharging the adhesive 200 from an adhesive dosing port H20. The ultraviolet irradiation unit 30 irradiates the adhesive 200 dosed from the adhesive dosing port H20 with ultraviolet light L. Here, the ultraviolet irradiation unit 30 irradiates the adhesive 200 with the ultraviolet light L along the mounting surface S10 before the adhesive 200 dosed from the adhesive dosing port H20 is applied to the surface of the panel 100.

Method for repairing delamination and moisture by heat, pressure and adhesive
11046461 · 2021-06-29 ·

A method for repairing aircraft window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.
