MECHANICAL PROPERTIES OF PAPER THERMOSETTING RESIN COMPOSITES BY VARIOUS PAPER MATERIALS

Recycling and reusing is a noticeable method for environment protecting. Recycled paper is one of the most successful cases as it contributes to energy saving, low cost, low wood consumption and environmental protection. During paper recycling process, many different kinds of raw materials can be used. Paperboards made of different raw materials showed different properties. In this study, three kinds of raw materials were selected to fabricate paperboards respectively combining with thermosetting resin, paperboards reinforced plastic composite was laminated by hand layup method. Detailed observation were carried out to analysis the molding stations including the tensile property which was investigated on both unnotched and notched specimens, besides, to investigate the anisotropy, tensile test was conducted on the specimens both in machine rolling direction and transverse direction. SEM was also employed to observe the materials and fracture area respectively.
