摘要： A bumper beam includes a first portion of a first material and a second portion of a second material. The first material has different material properties than the second material. For example, the first material may have a generally higher tensile or yield strength than the second material. In one embodiment, the first material comprises martensitic steel, while the second material comprises a dual-phase, multiphase, complex-phase or TRIP steel. In addition, the first material may have a different thickness than the second material. The bumper beam provides an improved strength to weight ratio than conventional bumper beams. This abstract is provided to comply with the rules requiring an abstract that allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.
摘要翻译：缓冲梁包括第一材料的第一部分和第二材料的第二部分。第一种材料与第二种材料具有不同的材料性质。例如，第一材料可以具有比第二材料普遍更高的拉伸或屈服强度。在一个实施例中，第一材料包括马氏体钢，而第二材料包括双相，多相，复相或TRIP钢。此外，第一材料可以具有与第二材料不同的厚度。保险杠梁比传统的保险杠梁提供了改进的重量比。提供该摘要以符合要求抽象的规则，允许搜索者或其他读者快速确定本公开的主题。提交它的理解是，它不会用于解释或限制权利要求的范围。

摘要： A hollow, reinforced, molded automotive hard top is made using a sheet of thermoplastic material with nanoparticles dispersed therein. The particles comprise less than 15% of total volume of the plastic sheet, at least 50% of the particles have a thickness less than about 20 layers, and at least 99% of the particles have a thickness of less than about 30 layers. The sheet is preheated and molded in an assembly having mold surfaces corresponding to the hard top configuration. Vacuum is applied to one side of the assembly and pressurized gas is applied to the opposite side of the assembly to force the sheet into conformity with the mold surfaces. After cooling, the conformed sheet is transferred to another mold assembly, where a reinforced plastic melt having a blowing agent is applied. Together, the solidified melt and the conformed plastic sheet form the hard top.
摘要翻译：一种中空的，增强的，模制的汽车硬顶是使用其中分散有纳米颗粒的热塑性材料片制成的。颗粒占塑料片的总体积的15％以下，至少50％的颗粒具有小于约20层的厚度，并且至少99％的颗粒具有小于约30层的厚度。片材被预热并在具有对应于硬顶部构造的模具表面的组件中模制。将真空施加到组件的一侧，并将加压气体施加到组件的相对侧，以迫使片材与模具表面一致。冷却后，将合适的片材转移到另一个模具组件，其中施加具有发泡剂的增强塑料熔体。一起，固化的熔体和合适的塑料片形成硬顶。
