    • The invention relates to a process for the manufacture of an object, curved in one or more directions, from a package of at least one stacked ply containing polymeric fibres by the deforming thereof at elevated temperature, the process comprising imposing on the fibres a tensile stress at a temperature lying between the melting point of the fibres at the imposed tensile stress and 20° C. below the melting point, which tensile stress is high enough for the fibres to be drawn. This process allows objects, curved in one or more directions, to be produced from flat fibre plies without appreciable wrinkling using even fibre plies with low internal and/or mutual deformability and without material being drawn into the die in a controlled manner. The invention also relates to an object, curved in one or more directions, obtainable by the process according to the invention.
    • 本发明涉及一种用于通过在高温下使其变形而从包含聚合物纤维的至少一个层叠层的一个或多个方向弯曲的物体的方法,该方法包括在纤维上施加拉伸应力 在施加的拉伸应力下的纤维的熔点之间的温度和低于熔点的20℃的温度下,该拉伸应力足够高以使纤维被拉伸。 该方法允许在一个或多个方向上弯曲的物体由扁平纤维层制成,而使用甚至具有低内部和/或相互变形能力的纤维层并且没有材料以受控的方式被吸入到模具中而没有明显的起皱。 本发明还涉及通过根据本发明的方法可获得的在一个或多个方向上弯曲的物体。
