    • A syntactic structural foam product in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres and dry resin powder, of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. Resin powder collected as a waste by-product from resin coating materials can be recycled in the production of the desired product. The foam product is produced by first intermixing the microspheres and powdered resin by physical agitation of the mixture and depositing the mixture as a layer over a surface having a release agent thereover within a dimension defining region between boundary members and then supplying heat with or without pressure to the layer at a temperature and for a time period sufficient to effect a melting of the resin powder and thereafter cooling the resin in a hardened condition to integrate the mixture into the product desired after which the product is withdrawn from the forming zone. Reinforcing elements such as glass or carbon fibers can be selectively included in the mixture for predeterminable desired physical and mechanical properties.
    • 一种平板形式的复合结构泡沫产品或适用于复合层压材料的轻质结构芯的这种用途的弯曲三维形状由中空陶瓷微球和干燥树脂粉末的混合物制成, 分布在微球体的间隙中,用于在加热和冷却时将混合物整合成所需形式。 从树脂涂料中作为废弃副产物收集的树脂粉末可以在所需产品的生产中循环使用。 泡沫产品通过首先将混合物物理搅拌混合并将混合物作为一层层叠在具有脱模剂的表面上,在边界部件之间的尺寸限定区域内,然后在有或没有压力的情况下供应热量 在足以使树脂粉末熔化的温度和时间段内向层中加热,然后在硬化条件下冷却树脂,以将混合物整合到所需的产物中,然后将产物从成形区中取出。 加强元件如玻璃或碳纤维可以选择性地包括在混合物中以获得预定的所需物理和机械性能。

    • A syntactic structural foam product in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres and dry resin powder, of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. The dry resin powder in another embodiment of the invention includes unexpanded expandable powder which will expand into microballoons in the confined spaces in which they reside and effect a bonding relation with surrounding particles upon supply of heat to the mixture. The foam product is produced by thoroughly intermixing and depositing the mixture as a layer over a surface having a release agent thereover within a dimension defined region. Heat is then supplied, with or without pressure, to the layer at a temperature and for a time period sufficient to effect a melting or softening of the resin powder. Thereafter the resin is cooled to a hardened condition to integrate the mixture into the product desired after which the product is withdrawn from the forming zone. The mixture in layer form can be reinforced with honeycomb structures and/or with elements such as glass or carbon fibers selectively included in the mixture for predeterminable physical properties.
