“…And this could be attributed to the sintering process as SPS usually achieve better densification with negligible defect, minimal grain growth, and pores size acceptable for engineering applications over traditional methods. 29–31 Furthermore, the SEM microstructure of 6 wt% shows that the TiO 2 nanoparticles are distributed uniformly into the PI material in comparison with other weight percentage of reinforcement materials, such as 0, 2, and 4 wt% nanoparticles as can be seen in Figure 2. However, with aid of the SEM results, there is evidence that the TiO 2 nanoparticles hybridized with ECR glass/PI particles.…”

This paper presents the mechanical behaviour of novel class composites consisting of ECR-glass type reinforced polyimide (PI) composite loaded with TiO2 nanoparticles. ECR glass reinforced PI composites were fabricated by adding TiO2 particles at three different concentrations namely; 2, 4, and 6 wt% using 3D-Turbula dispersion and Spark Plasma Sintering (SPS) method. The morphologies, crystallinity, mechanical, and electrical properties of the produced composites were evaluated using scanning electron microscope (SEM), X-ray diffractometer, nanoindentation test, and LCR meter device. The SEM results revealed that the TiO2 nanoparticles were homogenously dispersed into the PI composites. The mechanical properties, such as hardness, stiffness, and elastic modulus of the pure PI and ECR glass reinforced PI composite was improved by the incorporation of TiO2 nanoparticles. Maximum hardness and elastic modulus values of 2.19 GPa and 13.99 GP, respectively, was observed in ECR reinforced PI composited loaded with 6 wt% TiO2 nanoparticles. In addition, ECR glass reinforced PI composites with 6 wt% TiO2 nanoparticles depicted the lowest dielectric constant (1.18), dielectric loss (1.14) and electrical conductivity (3.16 × 10−6 S/cm). Finally, the findings suggest the easy processability of PI nanocomposites and their potential for mechanical and electrical insulation applications.

“…As the Young's modulus of Ti-50 vol % NaCl, which was 5 to 10 GPa, was somehow lower than that of bone which was 10 to 40 GPa. According to Watanabe et al, 14) Young's modulus of porous Ti sintered at 973 K for 5 min by SPS was around 10 GPa. There were no differences between their and our results.…”

Because of its excellent biocompatibility, good corrosion resistance and relatively lower Young's modulus, Ti was suitable for biomaterial. It, however, showed still bigger Young's modulus comparing to the living bone. It was necessary to decrease the Young's modulus in order to avoid adversely affect to the bone, such as stress sheilding. In this study, porous Ti were fablicated to decrease the Young's modulus by space holder method from Ti/NaCl composites sintered using spark plasma sintering (SPS) method. The sintering condition and the size of NaCl affected to the porous structure and mechanical properties. According to the scanning electron microscope (SEM) observation and the relative density measurement of specimens sintered with several sintering conditions, the desirable sintering condition was concluded as 973 K of sintering temperature and 1.2 ks of sintering time. The specimens made from NaCl powder whose size were from 106 to 214 µm showed almost opened and connected pores. The Young's modulus was decreased with increasing the porosity.

In the present work an attempt has been made to fabricate Polyester based Titanium Functionally Graded Materials. Titanium particles are produced through conventional filing operation, by rotating Titanium rod of 50 mm diameter on lathe machine. Filing operation has been carried out at 650 rpm using a course file. The obtained powder was demagnetized to remove the foreign material related iron. Powders are subjected to sieving operation to get desired range of particle size i.e 300 microns. FGMs with 2.5 gm, 5 gm and 10 gm titanium by weight are fabricated through sedimentation technique. The quality of the FGMs is examined through liquid penetrant non-destructive testing. FGMs are tested and analyzed from density, hardness and optical microscopy point of view. Obtained results are compared and analyzed.
