The invention relates to the technical field of polymer composite materials for machine tools, in particular to an ultrahigh-strength composite material and a preparation process thereof. The ultrahigh-strength composite material is mainly prepared from a modified epoxy resin composition, an epoxy curing agent, fine aggregate, coarse aggregate and a filler composition, the ratio of the total mass of the modified epoxy resin composition and the epoxy curing agent to the total mass of the fine aggregate, the coarse aggregate and the filler composition is (38-44): (56-62); the mass ratio of the fine aggregate to the coarse aggregate to the filler composition is (80-120): 100: (20-50); the fine aggregate is ISO standard sand or quartz sand of which the granularity is less than or equal to 5.0 mm; the coarse aggregate is basalt macadam with the particle size of 5-12mm. The composite material can meet the requirements of various physical properties of machine tool bodies and base parts on materials, and has the excellent characteristics of light weight, high strength, wave absorption, shock absorption, good wear resistance, weather resistance, corrosion resistance and environmental protection.
本申请涉及机床用高分子复合材料技术领域，尤其是一种超高强度复合材料及其制备工艺。一种超高强度复合材料主要是由改性环氧树脂组合物、环氧固化剂、细骨料、粗骨料、填料组合物制成；改性环氧树脂组合物、环氧固化剂的总质量与细骨料、粗骨料、填料组合物的总质量之比＝(38‑44):(56‑62)；细骨料、粗骨料、填料组合物之间的质量之比＝(80‑120):100:(20‑50)；细骨料为粒度≤5.0mm的ISO标准砂或石英砂；粗骨料为粒度5‑12mm的玄武岩碎石。本申请具有能够满足机床床身及底座类零件对材料的各项物理性能要求，具有轻质高强、吸波减震、良好的耐磨性、耐候性、耐腐蚀性且绿色环保的优良特性。
