Studies from Peking University Further Understanding of Applied Polymer Science

June 17, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Applied Polymer Science have been presented. According to news reporting originating from Beijing, People's Republic of China, by VerticalNews correspondents, research stated, "In this work, a dual-frequency resonance tracking (DFRT) method was applied on atomic force acoustic microscopy (AFAM) and high-resolution, quantitative nanomechanical mapping of a glass fiber-reinforced polymer composites (GFRP) was realized. Results show that even using the single-frequency AFAM, the fiber, and epoxy can give very good contrast in amplitude images."

Our news editors obtained a quote from the research from Peking University, "The modulus mapping result on GFRP by DFRT AFAM was compared with that by dynamic nanoindentation, and it is found that DFRT AFAM can map the elastic modulus with high spatial resolution and more reliable results. The interface of GFRP was especially investigated using a 2 mu m x 2 mu m scanning area. Finite element analysis was implemented to investigate the effect of tip radius and the applied pressing force on the interface measurement using a sharp 'interface'. By setting a linear-modulus-varied interface with finite width in finite element analysis (FEA), similar comparison between FEA and AFAM experimental results was also implemented."

According to the news editors, the research concluded: "The average interface width is determined to be 476 nm based on the high-resolution modulus image, indicating that AFAM is a powerful method for nanoscale interface characterization."
