The invention relates to a method for manufacturing an aircraft central wing box. The aircraft central wing box is manufactured from a plurality of U-shaped profile sections (44) and C-shaped profilesections (46) made of composite materials and outer skins (48) of fiber reinforcements formed on the U-shaped profile sections and the C-shaped profile sections. The method is characterized in that the C-shaped profile sections (46) and the U-shaped profile sections (44) are obtained through a method involving a step of compressing the resin-impregnated fiber reinforcements at a pressure larger than or equal to 7 Pa and at a temperature less than or equal to 90 DEG C. The invention further relates to the aircraft central wing box obtained through using the above method. The dimensional accuracy and the geometric accuracy of the profile sections and the surface finishment of the profile sections can be optimized through the solution.
本发明涉及一种用于制造飞行器中央机翼箱盒的方法,该飞行器中央机翼箱盒从由复合材料制成的多个U形型材区段(44)和C形型材区段(46)并且从形成在所述U形型材区段和C形型材区段上的纤维增强物的外蒙皮(48)来制造。所述方法的特征在于,所述C形型材区段(46)和所述U形型材区段(44)通过涉及以大于或等于7巴的压力并且以小于或等于90℃的温度压缩经树脂浸渍的纤维增强物的步骤的方法获得。本发明还涉及采用上述方法制作的一种飞行器中央机翼箱盒。此解决方案使得可以优化所述型材区段的尺寸准确度和几何准确度以及其表面光洁度。
