A device to form a honeycomb has an upper continuous belt and a lower continuous belt disposed in parallel and carrying opposing cores. The belts act on liquid wax which is injected into an inlet of the device, with both belts moving in opposition. The inlet has in succession: a scraping zone disposed straight with respect to the upper belt; a zone for opening the cores, which has a certain curvature designed to receive a first injection of wax; and a third straight zone for sealing and expelling any excess wax. At an exit of the device, the longest length of the upper belt has multiple groups of magnetic and non-magnetic rollers for a local curving of the belt to progressively release the honeycomb.

A method for continuously fabricating a composite sandwich structure includes the steps of: (1) moving a laminate, substantially continuously, through a preheating zone, wherein the laminate includes a first face sheet, a second face sheet and a core sandwiched between the first face sheet and the second face sheet; (2) preheating the laminate to a preforming temperature above a glass transition temperature of the laminate and below or equal to a crystalline melt temperature of the laminate as the laminate is being moved through the preheating zone; (3) moving the laminate, substantially continuously, through a consolidation zone; and (4) consolidating the laminate as the laminate is being moved through the consolidation zone to form a continuous length of the composite sandwich structure.

A composite structure assembly includes a composite core including a flexible base and a plurality of cells extending from the flexible base. The composite core is conformable to different shapes. The plurality of cells are configured to move in response to movement of the flexible base. At least one of the plurality of cells may include a central column connected to a first flared end and a second flared end that is opposite from the first flared end.

An insulating molding (1) for a housing of at least one battery cell is disclosed, specifically for a housing of at least one lithium-ion battery cell, wherein, on at least one molding sidewall (3a, 3b) of the insulating molding (1), a depression (5) is configured, which is constituted by means of a reduced wall thickness, in order to reduce the force acting on the battery cell.

In the present disclosure, a method may include forming a three-dimensional composite fiber pre-form by three-dimensionally weaving a plurality of composite fibers. The composite fiber pre-form includes a plurality of open cells formed adjacent to and interlocked with each other, and a composite fiber forms at least a portion of a first side of a first open cell and at least a portion of a second side of a second open cell. The first open cell and the second open cell are adjacent to and interlocked with each other.

A process for manufacturing a composite structure includes: providing first mandrels, each first mandrel including a base and a plurality of projections arranged longitudinally along and projecting vertically out from the base; providing second mandrels; providing first ribbon plies, each first ribbon ply including a sheet of fibrous material; arranging each first ribbon ply with a respective first mandrel, the arranging of each first ribbon ply including substantially covering each surface of each of the projections of one of the first mandrels with a respective first ribbon ply; mating each second mandrel with a respective first mandrel such that each first ribbon ply is sandwiched between a respective first mandrel and a respective second mandrel; and curing resin disposed with the first ribbon plies to consolidate the first ribbon plies together and form a fiber-reinforced composite core structure of an acoustic panel.

In a transmission case mounted on a FF type vehicle, the transmission case includes a resin side cover formed at a front side of the vehicle. The resin side cover constitutes a vehicle front side surface section of an oil storage section configured to store oil in the transmission case, and includes a protrusion disposed above an oil surface of the oil stored in the oil storage section and protruding toward the front side of the vehicle to constitute the foremost section of the transmission case and a fragile section disposed between the protrusion and the oil surface of the oil and extending transversely in a lateral direction.

An anti-icing honeycomb core composite manufactured by forming an electromagnetic wave absorption layer by using dielectric fiber, molding the electromagnetic wave absorption layer into a honeycomb core structure by using a molded part including a first base, a second base, and an inner block, hardening the honeycomb core structure, and removing the molded part. The molding step includes first stacking, on the first base including a plurality of grooves in which the inner blocks each having a hexagonal column shape are able to be seated, a plurality of the inner blocks and a plurality of the electromagnetic wave absorption layers as the honeycomb core structure so that the electromagnetic wave absorption layer is disposed between the plurality of inner blocks, and second stacking covering the inner blocks and the electromagnetic wave absorption layers stacked on the first base with the second base having the same shape as the first base.

A method for producing a composite tank is disclosed. The tank has a continuous fiber reinforcement, a prismatic shape, and a thickness e for the storage of a pressurized gas in an internal cavity of the tank. The tank comprises fibers extending between two non-contiguous faces of the tank through the internal cavity. The method includes: (i) obtaining a prismatic fibrous preform having a thickness e comprising three-dimensional continuous reinforcements throughout its thickness; (ii) impregnating an outer layer of the preform with a polymer over a thickness of less than of the thickness e so as to constitute a composite outer shell extending over all faces of the prism; and (iii) forming a sealed layer constituting an inner lining, having a thickness of less than 1/10th of the thickness e between the outer shell and the fibrous network contained in the cavity of the tank.

Embodiments disclosed herein relate to polymer resins having a first thermoset and one or more additional components (e.g., a second thermoset and/or a thermoplastic), composite laminates including the same, methods of making and using the same, and composite laminate structures including the same.
