In this study, the structural and material properties of a new semi-rigid material, Scotchcast SoftCast (SCS), were compared to the properties of two rigid materials, plaster of paris (POP) and Scotchcast Plus (SCP). Cylinders and flat beams made from 4, 6, 8, and 10 layers of each casting material were tested in three-point bending and diametrical compression. Initial stiffness and yield force values of SCS casts were significantly lower than for casts of SCP and POP made of the same number of layers. Casts made from SCS may be indicated for non-rigid applications, but not where rigid immobilization is required.
在本研究中,将一种新型半刚性材料Scotchcast SoftCast(SCS)的结构和材料性能与两种刚性材料——熟石膏(POP)和Scotchcast Plus(SCP)的性能进行了比较。对由每种铸造材料的4层、6层、8层和10层制成的圆柱体和平板梁进行了三点弯曲和径向压缩测试。SCS铸件的初始刚度和屈服力值明显低于相同层数的SCP和POP铸件。由SCS制成的铸件可能适用于非刚性应用,但不适用于需要刚性固定的情况。
