    • A new composite damping material is presented which exhibits an enhanced ability to dampen mechanical oscillations. The enhanced damping properties of this material are achieved through the entrapment of highly viscous damping fluids within the pores of a porous material (such as: an expanded polymer, felt, foam, fabric, metal, etc.). The entrapment of the fluid within the porous scaffold prevents flow, providing a stable composite which may be shaped into useful articles. Such a construct allows utilization of the high performance damping properties of fluids which, in pure form, are too fluid-like for most practical applications (which typically require a solid, stable, material). This composite, possessing damping performance approaching that of certain fluids, combined with stability in a solid form, can be used in many applications where materials are needed to damp the vibration of mechanical systems. Such applications include, but are not limited to, damping of vibrations which produce noise or degrade performance in airplanes, automobiles, space structures, machine tools, sporting goods, disk drive components and assemblies, electrical/electronic components such as transformers, electrical cables, etc. In addition, these composites may be used to alter or tune the mechanical response of a variety of systems to produce desired impulse or vibrational response.
    • 提出了一种新的复合阻尼材料,其具有增强的抑制机械振荡的能力。 该材料的增强的阻尼性能通过在多孔材料(例如:膨胀聚合物,毡,泡沫,织物,金属等)的孔内截留高粘性阻尼流体来实现。 流体在多孔支架内的捕获可防止流动,提供可形成有用制品的稳定的复合材料。 这种结构允许利用流体的高性能阻尼性能,其在纯形式下对于大多数实际应用(通常需要固体,稳定的材料)而言太流体状。 该复合材料具有接近某些流体的阻尼性能,结合固体形式的稳定性,可用于许多需要材料以阻尼机械系统的振动的应用中。 这样的应用包括但不限于在飞机,汽车,空间结构,机床,运动用品,盘驱动部件和组件中产生噪声或降低性能的振动的阻尼,诸如变压器,电缆的电气/电子部件, 此外,这些复合材料可用于改变或调整各种系统的机械响应以产生期望的冲击或振动响应。

    • A foamed molding having a fastener comprises: a foamed body (41), pile threads (42) each having a leading end protruding from the front side of the first foamed body and a rear end exposing from the back side of the first foamed body, and a foamed body (60) formed on the back side of the foamed body (41). The pile threads (41) each have an extended portion (43) for locking at the leading end thereof. A part of stock solution for forming the foamed body (60) is impregnated from the back side of the foamed body (41) to thereby form an impregnated layer (61) between the foamed body (41) and the foamed body (60), the impregnated layer (61) functioning to secure the rear ends of the pile threads (42). The foamed molding having a fastener can follow a contraction phenomenon produced in the foaming process of foam resin when an impregnated type foamed molding is formed on the back side of the face-like fastener.
