The following can be obtained through experiments: the impact strength is also higher when the titanate coupling agent NXT-201 is present at a higher proportion in the coupling agent, whereas the flexural strength is higher, but not to the same extent, when the silane coupling agent is present at a higher proportion in the coupling agent. The transport case mainly prevents impact damage, so the proportion of titanate coupling agent NXT-201 in the coupling agent should be increased.
The steam explosion treatment is that under the physical and chemical actions, most hemicellulose is degraded, part lignin is dissolved, and the fiber bundle is increased by explosion, which is beneficial to improving the compatibility of the fiber and the matrix; when the coupling agent is processed, the inner layer fiber and the matrix have stronger interface bonding force.
NaOH can destroy ester bonds of lignin, open hydroxyl groups of partial fibers and increase porosity, cellulose cannot be hydrolyzed, the silane coupling agent can react with the hydroxyl groups on the surfaces of the fibers more easily, and the adhesion between the fibers and a PP matrix is enhanced. It has been shown that alkali treatment can lead to fibrillation of the fibres, i.e. splitting of the fibre bundles in the composite into smaller fibres, decreasing the fibre diameter, increasing the aspect ratio and increasing the effective contact area with the matrix.
