High-density ceramic fiber board with curved surface structure and preparation method thereof
The invention provides a high-density ceramic fiber board with a curved surface structure. The curvature radius of the high-density ceramic fiber board with a curved surface structure is larger than or equal to 500 mm. The thickness is 5-15 mm; and the central angle of the circular arc is 20-80 degrees. Due to the fact that the resilience of a high-density board wet blank is poor, when the curvature radius is smaller than 500 mm and the product thickness is larger than 15 mm, cracks are prone to occurring at the two ends of the curved surface; after the curvature radius is increased, the tensile stress of the high-density board wet blank is correspondingly reduced, so that the thickness of the product can be increased without cracking. The invention further provides a preparation method of the high-density ceramic fiber board with a curved surface structure.
本发明提供了一种曲面结构的高密度陶瓷纤维板，所述曲面结构的高密度陶瓷纤维板的曲率半径≥500mm；厚度为5～15mm；圆弧中心角为20°～80°。在本发明中，由于高密度板湿坯本身的回弹性较差，当曲率半径低于500mm，产品厚度大于15mm时，弯曲面的两端容易出现裂纹；当曲率半径扩大后，高密度板湿坯的拉伸应力相应减小，因此产品厚度可以增大而不出现开裂问题。本发明还提供了一种曲面结构的高密度陶瓷纤维板的制备方法。
