    • In accordance with embodiments of the herein disclosed subject matter it is described a method of producing a spring (130) wherein the spring (130) comprises at least the tool windings and is formed of a composite material, wherein the composite material and comprises a matrix (120) and the base element (102). The method comprises providing an intermediate product (100, 200) comprising the base element (102) within an outer envelope (104), wherein the base element (102) provides a plurality of cavities (118) within the altar envelope. Further, the method comprises shaping the intermediate product (100, 200) into the at least two windings and introducing the matrix (120) into the cavities (118) before, during or after the shaping of the intermediate product (100, 200). After shaping of the intermediate product (100, 200), the method comprises hardening the matrix (120) in the cavities (118). Optionally, the intermediate product (100, 200) comprises a matrix supply fluid path (110) which promotes flow of the matrix (120) through the intermediate product (100, 200) in order to fill the plurality of cavities (118).
    • 根据本文公开的主题的实施例,描述了一种制造弹簧(130)的方法,其中弹簧(130)至少包括工具绕组并且由复合材料形成,其中复合材料并包括矩阵 (120)和基本元件(102)。 该方法包括在外壳(104)内提供包括基座元件(102)的中间产品(100,200),其中所述基座元件(102)在所述穹顶外壳内提供多个空腔(118)。 此外,该方法包括将中间产品(100,200)成形为至少两个绕组,并且在中间产品(100,200)成形之前,期间或之后将基体(120)引入空腔(118)。 在中间产品(100,200)成形之后,该方法包括使空腔(118)中的基体(120)硬化。 可选地,中间产品(100,200)包括促进基质(120)通过中间产物(100,200)的流动以填充多个空腔(118)的基质供应流体路径(110)。
