Purpose: The paper presents the results of investigations of dynamic properties for bone cement with different fillers by means of DMTA method. Addition of any substance causes the change in mechanical properties. Pure PALAMED material and material filled with four different fillers have been analysed. Design/methodology/approach: One of the methods of thermal analysis for polymeric materials has been used for investigations. DMTA method is based on the analysis of the signal (reaction) from the deformed material under particular conditions, at the changeable ambient temperature as well as vibrations frequency and amplitude. DMTA thermograms give information on change in storage modulus E' and the mechanical loss factor tgδ, which is responsible for dissipation of energy during deformation. Pure cement as well as the cement filled with: BiO-OSS and PORESORB bone graft substitute materials, Al2O3 ceramic material and powdered animal bones. Method of specimen preparation and proportion in which the specimens were prepared are presented in the text. Practical implications: As it results from the literature analysis, no investigations of such a wide group of fillers, both organic and inorganic have been carried out yet. The investigations enabled the storage modulus and tgδ to be determined for each of the prepared materials, thus to indicate the material whose properties enable this material to be used in further alloplasty surgeries for hip joint. Practical application of the results of the investigations described in this paper will be possible after long and comprehensive clinical trials. Originality/value: Original value of this paper are the results of tests since such an analysis has never been conducted by scientific environment working on this subject.
