	Optimizing and Evaluating the Biocompatibility of Fiber Composites with CaP Additives Suchý, Tomáš ; Sucharda, Zbyněk ; Balík, Karel ; Sochor, M. ; Bačáková, Lucie Composite materials based on a polyamide fabric (aramid) and a polydymethyl-siloxane (PDMS) matrix were designed for application in bone surgery. In order to increase the bioactivity, 2, 5, 10, 15, 20 and 25 vol. % of nano/micro hydroxyapatite (HA) and tricalcium phosphate (TCP) were added. The effect of the additives on the biocompatibility was studied. It appears that nano additives have a more favorable effect than micro particles on mechanical properties. For final application of the composites as substitutes for bone tissues, 15 vol. % of nano hydroxyapatite additives is an optimum amount: in this case both the mechanical properties and the biological properties are optimized without distinct changes in the inner structure of the composite.

	The Influence of Steam Sterilization Processes on the Micro- and Macromechanical Properties of Polyamide Fiber-Reinforced PDMS Composites for Medical Device Applications Sochor, M. ; Balík, Karel ; Sedláček, R. ; Suchý, Tomáš ; Sucharda, Zbyněk ; Šepitka, J. ; Lukeš, J. The effect of multiple steam sterilization processes on the structural integrity of the polymer matrix composite polydimethylsiloxane (PDMS) reinforced with polyamide fibers (Aramid) is investigated by 3- and 4-point bending tests and by nanoindentation.

	Sterilization Decomposition Evaluation of Radiolucent Composite Materials for Use in Medicine Sochor, M. ; Balík, Karel ; Suchý, Tomáš ; Sedláček, R. ; Sucharda, Zbyněk ; Beneš, J. ; Prokop, J. This study evaluates the resistance against multiple sterilization processes of radiolucent composite materials for use in medicine as an intraoperative imaging device material. The composite materials under investigation here are composed of carbon fibers, polyphenylene sulfide and polyetheretherketone matrix. The influence of multiple sterilization processes on changes in their mechanical and structural properties are determined. The radiolucency of the proposed composites is verified. Úplný záznam
