Lignin, cellulose and other compounds fill in the network-like structure[3].
The MRH-g-AM forms a rigid and flexible macromolecular spatial network structure.
The morphological structure of the MRH-g-AM was studied by scanning electron microscopy (SEM).
A FTIR study is also performed to investigate the chemistry of the MRH-g-AM.
Fig.2 shown SEM images at 1000× and revealed the surface structure of RH (a) and MRH-g-AM(b).

The effect on strength of incorporating a natural fibre into the composite is likely to be due to the fact that the fibre is still a small amount in composite with an inner structure prone to be broken by stress transferred by the matrix and thus acting to a certain degree, as a flaw which in turn acts as a crack initiator.
