Hybrid Titanium - High Modulus Carbon Laminates

目前钛合金因其具有较高的比强度而被广泛应用于航空航天结构中。近年来，超高模量碳纤维得到了发展。在本研究项目中，将开发一种具有高比强度和高比刚度的钛/高模量碳杂化复合材料。将使用无机基质，也将提供耐高温。主要目的是评估无机基体与钛的相容性以及制造复合板的可行性。这些板材将采用真空装袋技术制作，并将进行拉力和弯曲测试。关键问题是碳纤维与钛板之间的界面行为。如果成功，该复合材料将为高温、高比强度和高刚度结构部件的制造提供新的突破。这些组件将在航空航天、汽车和土木工程结构中具有极好的应用潜力。本项目将招收本科生。通过参与项目，他们将接触到最新的材料及其发展。

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.
