Fracture of Ceramic-Polymer Composite Biomaterials
Fracture toughness, strength, and elastic modulus of poly(methyl methacrylate) (PMMA)and poly(buty1 methacrylate) (PBMA)-impregnated alumina ceramics were measured as a function of polymer volume fraction, mean polymer particle size, and interfacial bonding between the polymer and ceramic. Fracture toughness was found to increase with increasing polymer volume fraction and decreasing polymer pa...
متن کاملCeramic Biomaterials: an Introductory Overview
A review of classes of biomaterials and their applications is presented. Particular interest is paid to bioceramics, calcium phosphates and hydroxyapatite which are the leading biomaterials employed today. Several methods for producing hydroxyapatite are presented, including the characteristics and disadvantages of each methodology reported in specialized literature. The main trends of the mode...
متن کاملPolymer and ceramic nanocomposites for aerospace applications
This paper reviews the potential of polymer and ceramic matrix composites for aerospace/space vehicle applications. Special, unique and multifunctional properties arising due to the dispersion of nanoparticles in ceramic and metal matrix are briefly discussed followed by a classification of resulting aerospace applications. The paper presents polymer matrix composites comprising majority of aer...
متن کاملFracture of ceramic/ceramic/polymer trilayers for biomechanical applications.
Fracture damage in trilayers consisting of outer and inner brittle layers bonded to a compliant (polycarbonate) substrate and subjected to concentrated surface loading is analyzed. The principal mode of fracture is radial cracking at the undersurface of the inner (core) layer, even in the strongest of core ceramics--other damage modes, including radial cracking in the outer (veneer) layer, are ...
متن کاملCurrent Research Progress of Ceramic Biomaterials in Japan.
The R&D of ceramic biomaterials has extensively progressed in Japan since commercial production of calcium phosphates of hydroxyapatite and β-tricalcium phosphate, A-W glass, chemicalsand SBF (simulated body fluid)-treated metals, and yttria-stabilized zirconia for dental and medical applications. The centers of R&D excellence in Japan consist of universities and national research institutes in...
