Abstract

Abstract: Silvergrass is a natural biomass and has great potential as reinforced material in composites. To investigate the interface failure mechanism of silvergrass composites, the displacement field information of the interfaces of melamine-urea-formaldehyde resin(MUF)-silvergrass, phenol-formaldehyde resin(PF)-silvergrass and urea-formaldehyde resin(UF)-silvergrass in the process of tensile shearing were abstracted with digital speckle correlation method(DSCM). Results indicated that strain concentration occurred in the two ends of interface and extended to interface center along the tensile direction. The interface fracture also occurred first in the two ends. The PF-silvergrass interface showed the most obvious strain concentration during the tensile process, while the MUF-silvergrass interface presented the highest bond strength with better strain distribution.
