The present disclosure refers to a method for manufacturing carbon fiber panels stiffened with omega stringers for the construction of aircraft structures, such as fuselage sections, wing panels, etc. One tubular pressure member is provided for each omega stringer of the structure to be manufactured, wherein the tubular pressure member is configured with the shape of the omega stringer. Each tubular pressure member is enclosed between the omega stringer and part of the laminate, and autoclave pressure is applied to the interior of the tubular pressure member, so that the tubular pressure member is used to consolidate the omega stringers and/or part of the laminate from the interior of these two elements, while these two elements are being co-cured or co-bonded in an autoclave. Imperfections on those internal surfaces such as resin wrinkles of the structure are reduced.

A device for absorbing heat generated by curing of a curable matrix material, particularly heat generated by curing of a curable matrix material embedding a textile structure including a number of reinforcing fibers is provided. The device includes at least one envelope element defining at least one inner volume, and at least one thermally conductive heat absorbing element disposed within the at least one inner volume of the at least one envelope element. In a further embodiment, the at least one envelope element may be built of or include at least one non-adhering material which does not adhere to the curable or cured matrix material.

A production method of pseudo-wood and pseudo-stone furniture or ornament material with natural grains has a characteristic in that, the magnesia, the magnesium chloride, the water and the glass fiber are used to function as the primary staple. Then, a determined amount of modifier, sawdust powder and talcum powder is added into the primary staple. Then, the mold and the framework are operated according to the determined steps. Then, the primary staple is shaped. Then, the primary staple performs an oxidation process to form the product. Thus, the product is directly manufactured by the mold, without needing multiple and complicated working steps.
