A composite web including a first continuous web having a first face and a second face; the first web includes a molded portion having at least one protrusion, at least partly delimited by a base portion, on the first face; the composite web includes a segment of a second continuous web joined to the second face of the first web at least at the base portion.

A tube includes a corrugated metal tubular member; and a first covering part that covers the outside of the tubular member, and forms a braided structure using a resin string member of which at least a part is covered by a metal having lower electrical resistance than that of a metal forming the tubular member. The tube can also include a third covering part made of an insulating resin arranged between the tubular member and the first covering part, and covers the tubular member, wherein the first covering part covers the third covering part.

A box is made of structural boards having a face plate (2) including a main body portion (2c) that is substantially in one plane and a peripheral portion (2a) surrounding the main body. The boards further include a base plate (3) having integrally formed protrusions. The lower surface of the face plate (2) is attached to and supported on top of the protrusions. A stiffener (4) connects the peripheral portion (2a) of the face plate (2) and the base plate (3) together. At least a part of the stiffener (4) is fixedly connected to the base plate (3), and at least another part of the stiffener (4) is fixedly connected to at least a part of a lower surface of the peripheral portion (2a) of the face plate.

A stiffened structural component for an aircraft includes a first material sheet with a first surface, and at least one elongate bulge that bulges out in a direction transverse to the first surface in order to stiffen the structural component, wherein each of the at least one bulge comprises two edges that extend along the first surface, wherein a continuous bulging surface extends between the edges, and wherein the bulges are formed integrally into the first material sheet through pressing.

An object of the present invention is to provide a fiber-reinforced composite material achieving both lightweight properties and mechanical properties, a laminate thereof, and a prepreg capable of easily molding a sandwich structure thereof. The present invention is a prepreg comprising a reinforced fiber substrate (B) impregnated with a resin (A), wherein the reinforced fiber substrate (B) exists in a folded state having a plurality of folds with a fold angle of 0° or more and less than 90° in the prepreg.

A multi-component housing having a length and comprising at least a first component comprising a first plastic material, a second component comprising a second plastic material, and a third component comprising a third plastic material. The housing includes at least one tolerance-elimination element made of the second plastic material and longitudinally attached to the first component along the housing's longitudinal axis. The tolerance-elimination element has an average length extending parallel to the housing's longitudinal axis, which average length is at least ten times less than the length of the housing. The third component at least partially forms an outer surface of the housing, so that the tolerance-elimination element is at least partially overmolded by the third plastic material.

An exemplary multi-dimensional load structure may include a base panel having a tiered structure with an upper layer, a lower layer, and at least one interior layer therebetween. The load structure may also have a glass layer applied to at least surfaces of each of the upper layer, the lower layer, and the at least one interior layer not in contact with an adjacent layer. The load structure may further have a coating applied to the exterior of the glass layer. The at least one interior layer may be configured to withstand a greater compressive force than the upper layer and the lower layer and/or the upper layer and the lower layer may be lighter than the at least one interior layer.

In order to satisfy a demand for various shapes of windows of a mobile terminal and manufacture a mobile terminal with a low price, provided is a mobile terminal comprising a display panel and a window assembly disposed on the front surface of the display panel, wherein the window assembly comprises: an outer window forming a front outer appearance; an inner window disposed on the rear surface of the outer window while having a space between the outer window and the inner window; and a resin disposed in the space to fix the outer window to the inner window.
