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.

Paper tubes are usually produced by expert workers who are trained from experience. The manufacture technology can also be developed by this empirical rule. The so-called expert is non-expert person who is trained in the daily working and improve the technology by himself. It is a task for middle and small-sized enterprises in how to train the workers in a short time effectively. This is not only for paper tubes production, but also for a small factory on how to inherit its technology in a short time effectively. The objective of this is to analyze the motion for paper tubes fabricating by observe difference between expert and non-expert at work site as one of “Great master’s work” in middle and small-sized enterprises.

In this research, the bamboo charcoal paperboards (BCPs) were manufactured by paper making method. The paperboards constitute of many layers and each layer could be produced by different fibers materials. Bamboo charcoal was used and combined with recycled paper such as magazine, newspaper and corrugated paper box and so on. The mechanical properties included tension, compression, and pealing were tested to evaluate its potential applications. The scanning electron microscope observation was also conducted on the bamboo charcoal particle. At the same time, the benefit of bamboo charcoal paperboards on promoting attention for study was also evaluated. For attention effects on study, questionnaire survey was conducted from student to evaluate the effects of BCPs environment on studying. The brain wave data could be obtained during this process and investigated. The results indicated bamboo charcoal walls have good effect on concentrate attention to study.

Recycled paper is helpful to reduce trash discharge, save resource and cost. Recycled paper tube is one of the most successful cases in application of recycled paper. It is an excellent choice for packing. It’s also used in the construction of temporary structures for both exhibition spaces or for rapid-recovery shelters in emergency operations. As paper tubes are laminated composite materials composited of paperboard which is inherent anisotropy materials, the research on mechanical property and fracture behavior becomes more complicated. In order to analyze deformation and fracture behavior of paper tubes under lateral compressive load, six types of paper tube fabricated with different kinds of paperboard and number of ply were examined in this study. The six types included three different kinds of paperboard. Cracks propagation was observed through lateral compression test process. At the same time, energy absorption in elastic stage was discussed between different paper tubes.Copyright © 2013 by ASME

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.
