A method for producing a composite component including a bottom layer, cover layer and honeycomb structure, including applying the honeycomb structure to the bottom layer wherein honeycomb chambers are formed. Honeycomb chambers are filled in a reinforcement region with a granular material and granular material is removed from other honeycomb chambers wherein each honeycomb chamber is filled up to a granular-material filling height and honeycomb chambers outside the reinforcement region are free of granular material. The cover layer is applied to the honeycomb structure wherein the honeycomb chambers are closed. The composite component is heated so the granular material in the honeycomb chambers expands to fill it with granular material and the cover layer, the bottom layer, the honeycomb structure and the expanded granular material harden, the density of the expanded granular material in the honeycomb chambers filled with granular material being dependent on the granular-material filling height.

A method of manufacturing a load structure may include first forming a panel having a first side and a second side. The method may then include trimming the panel, including clearing a fill passage through the panel from the first side to the second side. The method may then include applying an over rim coating on the second side of the panel via an over rim tool by which a resin may be injected through the fill passage to the second side. The method may further include performing final trimming of the panel, and finally performing final assembly to form the load structure.

Aspects herein provide for a remoldable article configured to attenuate or reduce the results of an impact. The article comprises a plate that is remoldable in a temperature range of about 41 degrees Celsius to about 43.3 degrees Celsius.

A method for producing an acoustically resistive structure includes the steps of creating, consolidating and cutting a first layer of reinforcing fibres embedded in a first thermoplastic resin having a first melting point so as to obtain an interlayer, a step of laying a second layer of reinforcing fibres against a first face of the interlayer, a second consolidation step of consolidating the second layer of reinforcing fibres embedded in a second thermoplastic resin having a second consolidation temperature lower than the first melting point of the first resin so as to obtain a non-perforated external layer bound to the interlayer, a step of perforating the external layer and a step of laying an internal layer on a second face of the interlayer. An acoustically resistive structure obtained from the method as well as a sound-absorption panel including such an acoustically resistive structure are also described.

A method of manufacturing a sandwich panel (100) includes: a step of preparing a plurality of sheet-like prepregs (211); a step of performing a first heating and pressurization process through a release film (25) on upper and lower surfaces of a laminate where the plurality of prepregs (211) are laminated such that the laminate is integrated to obtain a composite facing material (40); and a step of disposing the composite facing material (40) on each of an upper surface side and a lower surface side of a sheet-like core layer (10) having a honeycomb structure and integrating the laminate through a second heating and pressurization process, in which a pressure of the first heating and pressurization process is higher than or equal to a pressure of the second heating and pressurization process.

The present invention provides a laminated plate capable of not only achieving a reduced weight and an increased rigidity but also improving a sound absorbing performance, and a method for manufacturing the same. A laminated plate (1) is supposed to include a core layer (2) including a plate-shaped paper honeycomb structure (4) and a pair of fiber reinforcement layers (3) sandwiching the paper honeycomb structure (4) from both sides in a thickness direction and integrated with the paper honeycomb structure 4. The through-holes (5) of the paper honeycomb structure (4) are filled with a foam resin (6), and the core layer (2) is made up of the paper honeycomb structure 4 and the foam resin (6) filled in the through-holes (5). When the foam resin (6) is filled in the through-holes (5) of the paper honeycomb structure (4), the foam resin plate (6A) is pushed into the through-holes (5) as a filling material by utilizing a compression force of a mold (11).
