摘要： A syntactic foam-core material and method for its production are disclosed wherein glass microspheres and chopped fiberglass are dispersed within a slurry comprised of a suitable resin such as an epoxy and a suitable solvent such as methyl ethyl ketone. Under carefully controlled vacuum and rate of addition conditions, the microspheres and chopped fiberglass are added to the slurry to form a light weight syntactic foam-core material. The material may either be stored under cold conditions for use at a later time as a B-stage material or it may be shaped and/or molded to conform to a desired configuration which, for example, may correspond with a desired component part. After curing, the material may be machined to final dimensions. The material may be characterized as a tightly packed network of resin-coated microspheres spaced by controlled, yet random voids comprising at least 20%, and more usually, between 23 and 25% by volume, of the fully-cured material.
摘要翻译：公开了一种复合泡沫芯材料及其制备方法，其中将玻璃微球和短切玻璃纤维分散在由合适的树脂如环氧树脂和合适的溶剂如甲基乙基酮组成的浆料中。在精心控制的真空和加入速率条件下，将微球和短切玻璃纤维加入到浆料中以形成轻质复合泡沫芯材料。该材料可以在较冷的条件下储存以供以后使用，作为B级材料，或者可将其成型和/或模塑成符合例如可能对应于所需组分部分的所需构型。固化后，材料可以加工成最终尺寸。该材料可以被表征为通过控制但无规的空隙隔开的树脂涂覆的微球的紧密堆积网络，其包含完全固化的材料的至少20％，更通常为23至25体积％。
