Abstract:

The paper pulp compression molding material is one of the most commonly used materials in packing industry. Their mechanical properties attract attentions from professional visitors and researchers. It is a difficult work to test the mechanical properties as the paper pulps are thin, anisotropic and sometimes wet. To spray ink spots with the surface of the specimens is not allowed either. The digit image frequency correlation method (DIFC) is presented in the paper, the information carrier of the displacement is the nature texture on the tested surface. Image acquiring and analysis are accomplished by the CCD camera and computer. From the displacement field strain distributions were obtained and the mechanical properties of the paper pulp compression molding material were evaluated. The test system is simple and the sensitivity is adjustable. DIFC is approved a suitable test method for paper pulp compression molding material.
