    • There is provided a method of constructing a laminate vehicle body shell component, comprising forming a damping prepreg or semipreg comprising a sheet-like curable prepreg or semipreg comprising resin and structural fibres having intimately contacted thereto a damping layer (14), wherein the damping layer (14) is formed by immersing a fibrous open web material in a solution of damping material and removing the solvent by evaporation, laying down the damping prepreg or semipreg, and forming the damping prepreg or semipreg into the eventual shape of the body shell component; either before or after, laying down additional fibre structural layers (12, 16) to form a curable laminate vehicle body shell component, then exposing the laminate to elevated temperature and optionally elevated pressure, thereby to cure the laminate to produce the laminate vehicle body shell component.
    • 提供一种构造层压车身壳体部件的方法,其包括形成阻尼预浸料或半平板,其包括片状可固化预浸料或半树脂,所述半固化片包含树脂和与其紧密接触的阻尼层(14),其中所述阻尼层 (14)通过将纤维性开纤网材料浸入阻尼材料溶液中并通过蒸发除去溶剂而形成,铺设阻尼预浸料或半胱氨酸盐,并将阻尼预浸料坯或半成品制成最终形状的壳体组分; 在之前或之后,放置另外的纤维结构层(12,16)以形成可固化的层压车身壳体部件,然后将层压板暴露于升高的温度和任选的高压,从而固化层压板以产生层压车身壳体 零件。
