Deformation Characteristics of Fiberboard Due to the Localized Heating
Year: 2025
Type: article
Abstract: In this study, we investigated the deformation characteristics of fiberboard used for the preparation of metal casting molds due to the localized heating caused by the high-temperature load. Through high-temperature heating experiments on fiberboards (MDF, LDF, HDF) and woods (White ash, Balsa, Ebony), it was revealed that the localized heating causes expansion and dent in the materials. The expansion is due to the behavior of moisture inside the material, and the dent is due to the deterioration of surface strength caused by pyrolysis of cellulose in the materials. We also clarified the effects of the physical properties and structure of the material on the height of expansion and the depth of dent.
