深水浮力材料需具有高的强度和尽可能低的密度。为了开发它,人们在高的强度和尽可能低的密度间寻求平衡。我们研制出一种由树脂基体填充微小的空心球构成的一类复合材料。这类材料的性质取决于基体树脂的类型、空心球的种类及各种成分的百分比,同时也取决于成型技术。将热电厂粉煤灰中分选出的玻璃微珠填充于热固性的环氧树脂 Deepwater buoyancy materials need to have high strength and as low a density as possible. To develop it, people seek balance between high strength and the lowest possible density. We have developed a kind of composite material composed of tiny hollow spheres filled with a resin matrix. The properties of these materials depend on the type of matrix resin, the type of hollow spheres, and the percentage of various components, but also on the molding technique.
