摘要
本文探讨了铝覆层夹芯碳纤维增强铝基(CF/Al)复合材料燕尾榫头的制备及其力学性能。采用T700-12K碳纤维和ZL207铝合金,通过液固浸渗挤压工艺,在660~715℃的不同温度下进行浸渗测试。结果显示,浸渗温度的升高显著提升了试样的拉伸强度(154 MPa)和剪切强度(88 MPa),尤其在700~715℃时,复合材料表现出均匀的碳纤维分布和无明显缺陷。研究还分析了温度梯度对浸渗行为的影响,发现优化的浸渗压力(45 MPa)及适当温度有助于提高浸渗质量。测试结果表明,制备的复合材料具有优异的力学性能和良好的加工适应性,为其在实际应用中提供了可靠依据。
This study explores the preparation and mechanical properties of aluminum-clad core carbon fiber reinforced aluminum matrix(CF/Al)composite dovetail joints.T700-12K carbon fiber and ZL207 aluminum alloy were utilized,and infiltration tests were performed at various temperatures ranging from 660℃to 715℃using a liquid-solid infiltration extrusion process.The results indicate that increasing the infiltration temperature significantly enhances the tensile strength(154 MPa)and shear strength(88 MPa)of the specimens.Particularly within the temperature range of 700℃to 715℃,the composite demonstrated a uniform distribution of carbon fibers with no significant defects present.The study also analyzed the influence of temperature gradients on infiltration behavior,revealing that optimized infiltration pressure(45 MPa)and appropriate temperature contribute to improved infiltration quality.The testing results demonstrate that the prepared composite materials possess excellent mechanical properties and good processing adaptability,providing a reliable basis for their practical applications.
