Properties Of Composites

The properties of composites based on thermosetting polyester and barite for use in the radiological protection area have been investigated with the objective to study the effect of different variables in the attainment of composites. To verify the efficiency of the composites produced in relation to radiological protection, lead was adopted as reference. A factorial experimental design was carried out and the studied variables were: type of polyester resin (orthophthalic or isophthalic), coupling agent (titanate or organosilane) and the ratio of resin to accelerator, catalyst and barite. The variables analyzed were: efficiency for barring the X-radiation, apparent density and mechanical properties. The effect, obtained from the experimental design, due to ratio of resin to barite in the apparent density was 0.036. The average apparent density of the samples produced with barite/resin value equal 2.0 (weight ratio) was 2.16g/cm3, while the average density of the samples produced with the weight ratio of barite/resin equal 3.0 was 2.2g/cm3. It was observed same trend for the density to mechanical properties. It was observed that the samples attenuated X-ray radiation adequately up to 116 kV.

Bioresorbable Polymers

Mechanical properties of bioceramics are poor and need to be improved for biomedical applications. In order to do this, bioceramics may be strengthened by bioresorbable polymers. In this study, the mechanical properties of poly(ε-caprolactone), PCL, coated dense bioceramic pellets made of silica-contained calcium phosphates were studied and analyzed using a statistical experimental design in conjunction with Taguchi methods for optimization. The aim of this experimental work was to maximize the pellet flexural strength and minimize the amount of deposited PCL. The most important factors affecting the strengthening of the ceramic pellets were evaluated. Four independent processing variables (a removal technique of an excess polymer solution, concentration of PCL in the solution, a heat treatment temperature and the number of dipping) with three levels of variability were tested using an L9 (34) orthogonal array. A statistical experimental design using the analysis of means and orthogonal array was applied to optimize the responses of these variables. The optimal conditions for achieving the maximal flexural strength of the coated pellets at the minimal amount of the deposited PCL were determined. A high quality dense bioceramic pellets with ~ 10.5 MPa flexural strength and ~ 80 μm thickness (~ 21 mg weight) of the deposited PCL coating were manufactured as a result.

A 2³ factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing of binders on the mechanical properties. The results obtained from this study suggest that the nature (i.e. plastic/elastic) and ratio of binders coprocessed together alter the influence of C and P on TS and BFI.
