A honeycomb core for dimensionally stable components (e.g., a reflector) in sandwich construction with a plurality of cells with a triangular cell cross section made from carbon fiber reinforced plastic. The honeycomb core is assembled from flat laminate strips by plugging, wherein the laminate strips have slots running transversely to the extension direction respectively on their longitudinal side. The laminate strips are connected to one another in such a way that the slots of three laminate strips engage in a positive-locking manner in one another at a respective intersection point to form the corners of the cells of the honeycomb core.

A method is provided for managing the temperature of heat sensitive material located near a repair patch being thermally cured on a composite skin using a heating blanket. The method comprises configuring an assembly of thermally conductive cooling blocks to fit within a space between the heating blanket and the heat sensitive material. The assembly of thermally conductive cooling blocks is then installed against the skin within the space, forming a heat sink that conducts a portion of heat out of the composite skin away from the heat sensitive material.

Embodiments provide a helical layer structure including: a helical core member which is formed of a flexible, lengthy, flat plate-like core member and which is formed of a steel plate made of a metal material, such as iron; and a polymeric coating layer which is formed of a polymeric material such as a thermosetting elastic material or a thermoplastic elastic material, and which coats the helical core member. The manufacturing method of the helical layer structure includes: a feeding step of feeding a core member having flexibility; a supply step of supplying the polymeric material having fluidity; a coating step of coating the core member with the polymeric material; a cooling step of cooling a coated intermediate which is coated with the polymeric material; and a helix formation step of helically twisting the coated intermediate to form the helical layer structure.

Platforms for gas turbine engines are described. The platforms include a flow structure having a gaspath surface and a non-gaspath surface with a front end, a rear end, a first edge, and a second edge. A platform connector extends from the flow structure. A first layer forms a part of the gaspath surface and is a non-continuous layer terminating at the ends and the edges. A second layer forms a part of the platform connector and is a non-continuous layer terminating at the ends and the edges. The second layer contacts the first layer proximate the first and second edges. A third layer defines an internal void and is a continuous layer arranged between the first layer and the second layer and defines a part of the flow structure and a part of the platform connector.

The invention relates to a method for manufacture of a product or in completion of a product. A flexible mat (20) is manufactured from an incompletely cured thermo-setting plastic, wherein the mat comprises an article (10) of electrically conductive material. The incompletely cured mat (20) including the article (10) is then formed as a function of a forming tool or to lie against or for contact with a product, whereafter final curing of the mat (20) is executed by supplying electric power to the article (10) or by external heat application or ultraviolet light. The invention also relates to an arrangement and uses.

A heater panel includes a core and a heater/dielectric layer including a positive thermal coefficient (PTC) heater layer between a pair of dielectric layers. A structural facing is included, wherein the heater/dielectric layer is bonded directly between the core and the structural facing. A second structural facing can be bonded to the core opposite the heater/dielectric layer. An impact layer can be bonded to the structural facing, e.g., the first structural facing described above, opposite the heater/dielectric layer.
