Material information
Carbon fiber reinforced polymer, carbon fiber reinforced plastic, or carbon fiber reinforced thermoplastic (CFRP, CRP, CFRTP), is an extremely strong and light fiber-reinforced plastic which contains carbon fibers[1]. CFRPs can be expensive to produce but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, the superstructure of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications[2].
CFRPs are composite materials. In this case, the composite consists of two parts: a matrix and a reinforcement. In CFRP the reinforcement is carbon fiber, which provides the strength. The matrix is usually a polymer resin, such as epoxy, to bind the reinforcements together [3]. Because CFRP consists of two distinct elements, the material properties depend on these two elements.
The increasing use of carbon fiber composites is displacing aluminum from aerospace applications in favor of other metals because of galvanic corrosion issues [4,5].
Characterization brief
In this proposal, three characterization methods: Nuclear Magnetic Resonance Spectroscopy, Differential Scanning Calorimetry and Scanning Electron Microscope are selected and described in detail. Further rheological and mechanical properties also should be tested to better understand the material’s properties and finally the application range of this kind CFRP can be determined.
Nuclear Magnetic Resonance Spectroscopy (NMR)
Conclusion
In general, refer to the material performance table on other pages. Its excellent mechanical properties are the key to the use of this material, and these representations can show the performance of these materials to a certain extent and are an indispensable part of this material museum.
