In this study, the chopped carbon fibers and jute fibers were used to fabricate hybrid paperboard. The paper making process was used. Combined with unsaturated polyester resin, paperboard fiber reinforced plastic (FRP), carbon hybrid FRP and jute hybrid FRP were fabricated and the mechanical property included tensile test, bending test and Izod impact test were carried out to compared the mechanical property of these three kinds of materials. The drilled holes tensile test was also carried out to examine the drilled holes property. Scanning electron microscope was employed to observe the fracture characteristic on failure specimens. It was found due to the manufacture process of paperboard, the materials expressed obvious anisotropic property. The paperboard composite has an excellent static property but lower impact property compared with carbon hybrid FRP. [ABSTRACT FROM AUTHOR]

Fiber reinforced plastic composite (FRP) has gained remarkable development because of its excellent properties, such as low density, high stiffness, high strength, corrosion resistance, long fatigue life, and so on. However, as more and more products made of FRP, the rubbish of FRP is also increasing which has become an important problem to the environment. Recycling and reusing is a noticeable method to reduce trash discharge and to save resource. Although it is a more challenging work for FRP, many researchers have report their scores in this area, such as the group from The University of Nottingham who have developed a new technology to recycle the carbon fiber. The objective of this research is to make short fiber mat from recycled carbon fiber by paperboard making method. In this method the fiber can be made into very thin layers and be laid into mat. After that the mats were used to fabricate FRP and the tensile property of the materials was investigated. The property was evaluated between recycled carbon fiber and jute fiber as well as hybrid one. It was found that the hybrid one has better performance. [ABSTRACT FROM AUTHOR]
