Hybrid Titanium - High Modulus Carbon Laminates

点击翻译按钮获取中文摘要

Currently titanium alloys are being used for aerospace structures because of the high specificstrength. Recently carbon fiber with ultra high modulus has been developed. In this research program a titanium / high modulus carbon hybrid composite will be developed to obtain both high specific strength andhigh specific stiffness. An inorganic matrix will be used which will also provide high temperatureresistance. The primary objectives are to evaluate: the compatibility of the inorganic matrix withtitanium and the feasibility of fabricating composite plates. The plates will be made using vacuumbagging technique and will be tested in tension and bending. The key issue is the behavior of interfacebetween carbon fibers and the titanium plates. If successful, the hybrid composite will provide a new breakthrough for the fabrication of high temperature,high specific strength and high stiffness structural components. These components will haveexcellent potential for use in aerospace, automotive and civil engineering structures.Undergraduate students will be recruited for the project. Through their involvement in the projectthey will be exposed to latest materials and their development.
