Ceramic fiber board is a refractory material that maintains good mechanical strength after heating. Pump it into the forming tank and stir with compressed air. Put the mold into the forming tank, and use the principle of vacuuming to adsorb the fiber slurry on the mold. What is its bending resistance?
When we studied the ceramic fiberboard, we analyzed the fracture micro morphology of the reinforced silica sol shell after bending fracture. At this time, the enhancement effect of the matrix is not obvious, only 0.28 MPa and 0.45 MPa, an increase of about 12 to 19%. As the fiber content increases to 0.6% and 0.8%, the number of fibers on the fracture surface of the ceramic fiberboard gradually increases and is evenly distributed in the mold shell. This indicates that the fibers are well dispersed during the coating preparation process, so the fibers that participate in the strengthening effect The number has increased, thus showing an improvement in the overall strengthening effect.
At this time, diameter shrinkage can be observed on the fibers existing on the broken surface of the product, which is caused by elastic deformation in the process of fiber fracture and debonding. By increasing the number of fibers, the residual shell can be observed from the fibers on the fracture surface of the ceramic fiberboard, which indicates that the ceramic fiberboard effectively bears the load during the debonding process, which indicates that the experimental analysis results help to enhance the bending performance of the fiberboard .
