Abstract
In order to enable the recycling of FRP waste, the pulverization method is proposed based on surface grinding process. In the experiments, the pulverization characteristics are examined, and then, the change in the property of the FRP material pulverized to particles is confirmed. From the examination, the following were clarified: The FRP material can be pulverized with surface grinding process, and the sizes of the generated particles are almost 10μm or less. The size distribution of the generated particles hardly changes regardless of the change in grinding condition, such as depth of cut or feed rate. However, the increase in depth of cut or feed rate makes the particles easily cohere together. To improve the pulverization efficiency, the supply of the semi-cold-air is effective because this markedly prevents the particle cohesion. The pulverization improves the water suspension ability of FRP in water, and this gives FRP waste the possibility of recycling.
