Five series SnO2/C Morph-genetic composite materials were prepared using ramie fiber as biological templates, Sn(OH)4 sol as impregnant, and phenolic resin as supplementary adhesive. The influences of calcination temperature, holding time, and phenolic resin treatment on the mechanical wear property of the SnO2/C morph-genetic materials were studied. The results showed that when the calcination temperature reached 630 and holding time increased, SnO2 was reduced by C and CO to needle-like flakes and pellet mixed SnO/SnO2 tissue, and their pinning and supportive effects significantly increased wear resistance of the samples. Glass Carbon derived from phenolic resin decomposition and ramie carbon were difficult to distinguish, but glass carbon had obvious supportive and strengthening effects on ramie carbon walls. With the formation of homogeneous carbon membrane in the process of friction, the alternative distribution of soft carbon and hard carbon could effectively improve wear resistance of the matrix ramie carbon.
Punching bonding made for study context and Autoform selected for platform, numerical simulation of stamping was carried under different shapes, different materials, different parameters, and the different simulation results was gained . And deformation, the thickness of the forming limit analysis of simulation results, etc., and thus such important parameters as the thickness of sheet metal, punch diameter, the speed and the size of power punching and etc.,was modified and debuged, the combination of optimized process parameters of sheet metal was achieved in the final. Therefore, AutoForm not only can be used to overcome the difficulties,which there is no standard available, relying on repeated experiments to determine the parameters of the connected so as to achieve green design stamping; but also be made for stamping die design and production of connections to increase the efficiency and the expansion of the stamping connections the scope of the application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
