“…Volume 78 the bonding between PVA and (NaI) salt, which increases the density of the effective mechanical bond as well as increasing the packing and interlocking, which reduces the movement of the base material molecules , thus increase the resistance to scratching and cutting [11], i.e the addition of salt (NaI) led to a lack of flexibility and increase in the surface resistance to penetration, When attaching at the weight ratio (16wt%) the hardness value decreases significantly, the decrease in the hardness due to the high viscosity gained by the prepared composite material when adding the high weight ratios of the filler materials (NaI) salt inside the (PVA) polymer when it is in a liquid state and that caused the difficulty penetration of sodium salts into the Interfaces distances of polymer (PVA) in the prepared composite material which is due creating many gaps within the prepared composite material at hardened, which was caused a decrease in the value of hardness [7]. Table 2 shows the hardness values of (PVA-NaI) composites films.…”

Abstract. The effect of Sodium Iodide (NaI) salt on mechanical properties of polyvinyl alcohol (PVA) was studied in this work. The interaction between (NaI) salt and polymer (PVA) was investigated by (FTIR) spectroscopy. The effect of (NaI) salt on the mechanical properties of the polymer (PVA) was studied by hardness and tensile tests. FTIR spectra analysis of pure and (NaI) filled (PVA) films showed that the vibrational modes have changed due to the effect of filler salt in the polymer (PVA). Hardness test showed that the hardness increases unsystematically with increasing the weight ratio of added sodium iodide salt except the weight ratio of (16 wt %) compared with pure (PVA) film, while the experimental results of the tensile test for (PVA-NaI) composite films showed unsystematic change of tensile strength, elongation at break and Young's modulus after filling with different weight ratios of (NaI) salt compared with pure (PVA) film.

“…The efficiency of load transfer between the matrix and reinforcements depends directly on the bonding which in turn depends on wetting of surfaces. The non-uniform distribution of particles may reduce wetting and bonding, and as a result of excessive particles that are not well dispersed in the polymer, stress concentrations and defects will be created in the matrix, and thus decreases the tensile strength [7]. In general, the clustering or entanglement of particles and/or fibers in some areas and the irregularities may create resin poor areas and so weaken the forces of adhesions well as creating many of defects within the composites and other defects formed within the fiber layer itself and that this will lead to the generation of…”

Abstract:In this work, glass fiber reinforced epoxy composites were fabricated. Epoxy resin was used as polymer matrix material and glass fiber was used as reinforcing material. The main focus of this work was to fabricate this composite material by the cheapest and easiest way. For this, hand layup method was used to fabricate glass fiber reinforced epoxy resin composites and TiO 2 material was used as filler material. Six types of compositions were made with and without filler material keeping the glass fiber constant and changing the epoxy resin with respect to filler material addition. Mechanical properties such as tensile, impact, hardness, compression and flexural properties were investigated. Additionally, microscopic analysis was done. The experimental investigations show that without filler material the composites exhibit overall lower value in mechanical properties than with addition of filler material in the composites. The results also show that addition of filler material increases the mechanical properties but highest values were obtained for different filler material addition. From the obtained results, it was observed that composites filled by 15wt% of TiO 2 particulate exhibited maximum tensile strength, 20wt% of TiO 2 particulate exhibited maximum impact strength, 25wt% of TiO 2 particulate exhibited maximum hardness value, 25wt% of TiO 2 particulate exhibited maximum compressive strength, 20wt% of TiO 2 particulate exhibited maximum flexural strength.

A promising group of biomaterials assigned for the production of intramedullary nails are composites with a polylactide (PLA) matrix, reinforced with wires made of magnesium alloys and carbon fibres. The paper describes the effect of the composition of magnesium alloy wires, their number and orientation in the composite, as well as their connection with differently directed long carbon fibres, on the mechanical properties and the degradation rate of the obtained intramedullary nails. Among the tested implant prototypes, the best mechanical characteristics and a gradual and uniform course of magnesium alloy wires were exhibited by the PLA + CF1D + MgI composite nails (with a unidirectional orientation of carbon fibres and an axially oriented single Mg alloy wire). The strength of these nails became gradually decreased with the incubation time, which should allow for a gradual loading of the bone. In the case of the PLA with only magnesium alloy wires (without carbon fibres), the increase of the number of wires, on the one hand, stimulates the improvement of the nails' strength, yet on the other hand, a higher content of magnesium alloys in the PLA matrix affects the nails' faster resorption.
