Cocontinuous composites consisting of a porous calcium phosphate matrix (hydroxyapatite, HA, or βtricalcium phosphate, TCP) filled with poly(d,llactide) (PDLLA) were produced with two different methods: in situ polymerization of d,llactide monomer inside the matrix, or infiltration of the matrix with molten polymer. The influence of the calcium phosphate matrix as well as the ...
phosphate – Zirconia composites have been studied, but its mechanical properties are generally inadequate for many loadcarrying applications. Hence, fluorapatite can be used to ameliorate the mechanical properties of tricalcium phosphate – zirconia composites [12]. In fact, Fap is an attractive
Nevertheless, the mechanical properties of openporous scaffolds are often correlated with their porosity, with controversial findings about the validity [24–26]. Furthermore, in addition to the mechanical properties, cell biological compatibility also plays an important role in .

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra226) and strontium in the gastrointestinal (GI) tract.
Jan 14, 2019· Because of the existence of pores, calcium phosphate exhibits mechanical properties such as high brittleness, low impact resistance, and low tensile stress . However, its compressive strength is better than that of natural human bone, and it is used in nonload bearing implants, defect filling, and coating methods.
Nov 12, 2019· The addition of carbon nanotubes has been shown to improve the mechanical properties of CPCs, particularly their fracture strength and toughness. 39,164 In another study, an injectable bone substitute material made of calciumdeficient HA and ed gelatin has been proposed to promote bone ingrowth. 141 Recently, a copperdoped CPC formulation ...
The aim of the present study was to compare the mechanical properties of arterial and venous tissueengineered vascular constructs produced by the selfassembly approach using cells extracted from either the artery or vein harvested from the same human umbilical cord.
Jun 24, 2019· The mechanical properties of human bone, additively manufactured PGF 10 composites, and a continuous PGF/PLA composite are listed in Table 2. Comparing with the mechanical properties of cortical bones, the (dry) flexural strength of the PGF 10 composite is a close approximation, while the flexural modulus is much lower.
