    • Composite materials comprising at least 70 volume % of particles of finely powdered inorganic material in a matrix of polymer material are made by forming separate mixtures of the components in respective liquid dispersion media, mixing the mixtures to produce thorough dispersion of the components together, dewatering the mixture and forming green articles therefrom. The green articles are heated and pressed to a temperature sufficient to melt the polymer and to a pressure sufficient to disperse the melted polymer into the interstices between the inorganic particles. Mixtures of different inorganic materials may be used to tailor the electrical and physical properties of the final materials. The inorganic materials may be obtained in finely divided form by precipitation or coprecipitation. The articles preferably comprise substrates for use in electronic circuits. The invention also comprises apparatus for carrying out the method and the composite materials that result. Polymer particles of required small size are made by cooling a strip or rod to a brittle fracture temperature and feeding it against a moving grinding surface of coarseness to produce the particles.
    • 在聚合物材料基质中包含至少70体积%的细粉末状无机材料颗粒的复合材料通过在各自的液体分散介质中形成各组分的分离混合物,混合混合物以使组分完全分散在一起,脱水 混合物并从中形成绿色制品。 将绿色制品加热并压制至足以熔化聚合物的温度和足以将熔融的聚合物分散到无机颗粒之间的空隙中的压力。 可以使用不同无机材料的混合物来定制最终材料的电学和物理性能。 无机材料可以通过沉淀或共沉淀而以细碎的形式获得。 物品优选地包括用于电子电路的基底。 本发明还包括用于执行所产生的方法和复合材料的装置。 所需小尺寸的聚合物颗粒通过将条或棒冷却至脆性断裂温度并将其输送到移动的粗糙的研磨表面来制备颗粒。
