    摘要： A polymeric composite material contains a biodegradable polymeric material that can be biologically decomposed in soil. More specifically, it contains bacterial cellulose including ribbon-shaped micro-fibrils that can be biologically decomposed by microbes in addition to the biodegradable polymeric material and shows improved physical properties including tensile strength. Such a polymeric composite material can be prepared by a method including steps of causing predetermined microbes cultured in a liquid culture medium to produce bacterial cellulose, collecting and drying the produced bacterial cellulose into a powdery state and mixing the powdery bacterial cellulose and a biodegradable polymeric material to produce a composite material.

    摘要： This invention provides an acoustic vibrational material containing various fibers as the reinforcement material and having the epoxy resin as the matrix resin, wherein the epoxy resin is modified by a polybutadiene base elastomer containing not less than 90 mole percent of 1,2-linked units. The epoxy resin modified with the above polybutadiene elastomer exhibits a maximum value of loss coefficient at the temperature region near the room temperature. This region is much higher than that of the conventional epoxy resin modified with polybutadiene elastomer mainly including 1,4-linked unit. Decrease in elastic modulus of the epoxy resin with increase of temperature is lesser in the epoxy resin of the present invention, whereas larger in the conventional one. Thus compatibility between large internal loss and high elastic modulus is achieved.

    摘要翻译： 本发明提供一种包含各种纤维作为增强材料并具有环氧树脂作为基质树脂的声振动材料，其中环氧树脂由含有不少于90摩尔％的1,2-连接单元的聚丁二烯基弹性体改性。 用上述聚丁二烯弹性体改性的环氧树脂在室温附近的温度区域具有最大的损失系数值。 该区域比用主要包括1,4-连接单元的聚丁二烯弹性体改性的常规环氧树脂高得多。 本发明的环氧树脂中环氧树脂的弹性模量随着温度的升高而降低，而常规环氧树脂的弹性模量较小。 因此实现了大的内部损耗和高弹性模量之间的兼容性。

    摘要： A speaker diaphragm made of a resin containing a thermoplastic polymeric material is provided. The speaker diaphragm includes a changed portion formed on the diaphragm that is molded using the resin. The changed portion is formed by partially changing physical properties of the thermoplastic polymeric material for dispersing local vibrations based on a characteristic of local vibrations measured in advance.
