Hybrid Titanium - High Modulus Carbon Laminates

钛合金具有高的比强度，目前被广泛应用于航空航天结构.近年来，超高模量碳纤维得到了发展。在本研究计划中，将开发一种钛/高模量碳混杂复合材料，以获得高比强度和高比刚度。将使用无机基质，这也将提供耐高温性。主要目的是评价：无机基质与钛的相容性和制造复合板的可行性。钢板将采用真空装袋技术制造，并进行拉伸和弯曲试验。关键问题是碳纤维与钛板之间的界面行为。如果成功，混杂复合材料将为高温、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很好的应用潜力。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.
