织物结构对2.5D-C_f/Al复合材料微观组织与力学性能的影响
|
摘要
选用浅交弯联、浅交直联、层联结构的M40碳纤维机织物为增强体材料,采用真空气压浸渗法制备纤维体积分数为48%,基体合金为ZL301的2.5D编织M40碳纤维增强铝基复合材料(2.5D-Cf/Al),研究织物结构对2.5D-Cf/Al复合材料微观组织与力学性能的影响。结果表明:复合材料的致密度随着织物结构的改变而变化,其中浅交直联结构的2.5D-Cf/Al复合材料的致密度最大为98.5%;织物结构对复合材料的经向拉伸强度有较大影响,浅交直联结构的2.5D-Cf/Al复合材料经向拉伸强度最高,为414.85 MPa,其拉伸断口参差不齐,呈现出适中的界面结合强度;织物结构对复合材料纬向拉伸强度的影响较小,拉伸断口形貌差异不明显。
The vacuum gas pressure infiltration was used to compose the 2.5 D-C_f/Al composites with the volume fraction of 48%,of which the reinforced material was M40 carbon fiber with shallow-bend joint woven,shallow-straight joint woven and layer linking,the matrix alloy was ZL301,to find the effect of woven fabric structure on microstructure and mechanical properties of 2.5 D-C_f/Al composites.The results show that the density of 2.5 D-C_f/Al composites changes with woven fabric structure,the density of shallow-straight joint woven reaches maximum,98.5%;the woven fabric structure has great influence on the warp tensile strength of the composites;the warp tensile strength of shallow-straight joint woven reaches maximum,414.85 MPa,and its tensile fracture surface is uneven and shows moderate interfacial bonding strength;the fabric structure has little influence on the weft tensile strength of the composites,and the difference of tensile fracture surface is not obvious.
