Study on the microstructure of plant fiber/MMT/NR foaming composites
The micro structure of the microwave treated plant fiber and natural rubber(NR) foam composites as well as the morphology and distribution of the foam cell were investigated with SEM. The results show that the plant fiber forms an uniform pore structure after microwave treating. The morphology and the distribution of cell structure of the composite are effected by plant fiber and montmorillnate added. The plant fiber bonds well to the rubber matrix and forma special network structure. Furthermore, the microcellular surface of the foam becomes mote smooth because of the adding of montmorillnate. It also indicates that the optimal cell structure can be achieved by adding these two additives simultaneously.
