Composite structure and method for high strength door module

The invention provides a carrier for a carrier module of a motor vehicle door assembly and a method of manufacturing the same. The carrier includes a body having opposing wet and dry sides defined by an outer periphery, the body configured to be attached to the inner panel to substantially close the opening. The body is formed of a first material having a first density wherein a plurality of voids are disposed within the body. Each void of the plurality of voids has a second density, where the second density is less than the first density of the first material. 本发明提供了一种用于机动车辆门组件的承载件模块的承载件及其制造方法。该承载件包括本体，该本体具有由外周缘界定的相反的湿侧部和干侧部，该本体构造成附接至内面板以大致封闭开口。该本体由具有第一密度的第一材料形成，其中，本体内设置有多个空隙。多个空隙中的每个空隙具有第二密度，其中，第二密度小于第一材料的第一密度。
