Various reinforcements have been evaluated according to their effect on the mechanical properties of a silicone elastomer used for the preparation of maxillofacial prosthetic compositions. Emphasis was given to silica reinforcing fillers since fibrillar reinforcements [e.g., short aramid, glass or high modulus polyethylene (UHMPE)] seemed not to improve mechanical properties. An optimal behaviour at filler concentration 35% was determined. As a measure of the crosslinking density, the swelling of specimens immersed in various solvents, at 25 degrees C, was also investigated.
根据各种增强材料对用于制备颌面修复组合物的有机硅弹性体机械性能的影响进行了评估。由于纤维状增强材料（如短芳纶、玻璃或高模量聚乙烯（UHMPE））似乎无法改善机械性能，因此重点研究了二氧化硅增强填料。确定了填料浓度为35%时的最佳性能。作为交联密度的一种衡量方法，还研究了在25摄氏度下浸泡在各种溶剂中的试样的溶胀情况。
