A method of manufacturing a cured composite structure includes placing a radius filler element into a radius cavity extending along a length of a composite base member. The radius filler element is formed of a permeable material. The method also includes absorbing resin from the composite base member into the permeable material of the radius filler element. The method additionally includes curing or solidifying the resin in the radius filler element and in the composite base member to form a cured composite structure in which the resin bonds the radius filler element to the composite base member.

A method of manufacturing a cured composite structure includes placing a radius filler element into a radius cavity extending along a length of a composite base member formed of dry fiber material comprised of reinforcing fibers. The radius filler element is formed of a radius filler material. The method also includes infusing resin into the dry fiber material, and chemically reacting the resin with the radius filler material to create a mixture of resin and radius filler material along side surface interfaces between the radius filler element and the composite base member. The method additionally includes curing or solidifying the resin, and allowing solvent in the resin to evaporate causing hardening of the mixture and bonding of the radius filler element to the composite base member, and resulting in a cured composite structure.

A method of manufacturing a cured composite structure includes inserting a plurality of radius filler segments into a radius cavity extending along a length of an uncured composite base member to form an uncured structural assembly. The plurality of radius filler segments are placed in end-to-end arrangement within the radius cavity and each having opposing segment ends and being formed of a thermoplastic material. The method additionally includes heating the structural assembly at least to a base member cure temperature that causes the segment ends of end-to-end pairs of the plurality of radius filler segments to fuse together and form a continuous radius filler element that extends along the length of the composite base member. The method also includes allowing the structural assembly to cure to form a cured composite structure.

A composite member is provided with a bonding member made of a fiber-reinforced resin and a bracket in which the bracket is bonded to the bonding member via a resin. The bracket has a through-hole. The bonding member has a front surface side fiber-reinforced resin sheet and a rear-surface-side fiber-reinforced resin sheet. The front surface side fiber-reinforced resin sheet, the rear surface side fiber-reinforced resin sheet and the bracket are integrally bonded to each other by the resin in a state in which the front surface side fiber-reinforced resin sheet is inserted into the through-hole of the bracket to thereby enhance the bonding strength between the bonding member to the bracket.

A barrier including an outer edge and a plurality of elements such as bristles projecting inwardly from the outer edge. An electrical fitting including a body having an inner cavity, an aperture within the inner cavity between a first portion and a second portion, and a barrier positioned within or adjacent to the aperture, the barrier including an outer edge and a plurality of bendable elements. A method of assembling an electrical fitting including providing a barrier including an outer edge and a plurality of bendable elements projecting inwardly, placing the barrier within an inner cavity of the electrical fitting, placing a conductor into the second portion of the inner cavity, a distal portion of the conductor extending through the barrier and into a first portion of the inner cavity, and filling the first portion of the inner cavity with a sealing compound.

A self-healing glass panel includes first and second glass layers, a reservoir between the first and second glass layers, and a liquid healing agent for healing the first or second glass layers if a crack occurs. The liquid healing agent is entrapped in the reservoir by at least one of the first or second glass layers.

A housing assembly includes a housing, a printed circuit board (PCB) contained in a housing, and a cup-shaped cap having an interior and a flange portion. A tall component extending from the PCB is covered by the cap such that the tall component is disposed in the interior of the cap and the flange portion of the cap engages the PCB. A vacuum is applied and while maintaining the vacuum, an encapsulant is introduced into the housing to a level so as to cover the PCB and certain other components not the relatively taller component(s). When the vacuum is released, a pressure differential between the environmental pressure and the vacuum remaining in the cap interior forces encapsulant into the cap interior to a level higher than that outside of the cap. A multi-level height potting process is achieved.

A method suitable for manufacturing complex and stable objects of a wide range of sizes. The method involves producing an object structure by a generative production method and/or by an injection molding method, and producing a fiber-reinforced resin layer in at least one sub-region of the object structure.

The invention provides a method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).

An apparatus for modifying the geometry of at least one part of a turbine can include a shell assembly 3 that includes an outer shell that is shaped to modify the shape of a pre-existing element of a turbine. The outer shell 8 of the shell assembly 3 can be composed of a fiber-reinforced polymeric material and can at least partially define an inner cavity. The outer shell 8 can be bonded to a structure to modify the geometrical shape of that structure. Thereafter, a polymer casting 12 can be injected into the inner cavity via at least one injection port attached to the shell assembly. In some embodiments, one or more stiffeners 9 and/or a core 10 can be positioned within the inner cavity to help improve the bonding of the polymer casting 12 to the shell 2 and/or improve a structural property of the apparatus.
