Background and aim:Polymethyl methacrylate (PMMA) is broadly used as a removable prosthesis denture base. Silver Nano-particles (AgNPs) had been included to PMMA because of their antibacterial homes and higher thermal conductivity, at the same time as it had a destructive effect on the flexural strength and coloration stability that is probably resulted from the inhomogeneous combination. The motive of this research changed into to discover whether the addition of (AgNPs) to PMMA either in liquid form or in powder nation can enhance the flexural strength and the shade balance of PMMA. Also evaluating an edentulous menopausal lady as a multidisciplinary control after wearing a denture made from silver nanoparticles added to (PMMA) denture base. Materials and methods:Fifty specimens of heat cure acrylic resin had been organized for flexural strength and color stability. Twenty-five for each test that become divided into 3 groups. Group 1 was the control group (unmodified acrylic resin specimens) and group 2 turned into Nano silver introduced within the form of powder to the polymer of (PMMA), while group 3 was Nano silver brought in the form of liquid to the monomer of (PMMA). Group 2 and 3 specimens had been break up into subgroups A and B 5 each, with 0.2%, and 0.4 % wt. of Nano silver addition to (PMMA) respectively. A flexural strength was measured via the usage of an Instron regular testing machine. A double beam ultra-violet visible spectrophotometer was checked to the degree of coloration stability. One edentulous menopausal woman that present process treatment below a gynecologist for menopausal signs and symptoms was selected as a case report and received denture made out of silver nanoparticles added to acrylic resin and patient satisfaction became evaluated after 4 months. The results have been gathered tabulated and statically analyzed.Results: There has been a massive distinction in the flexural power values among all corporations (p< 0.05) relative to the non-changed heat treatment (control group). Acrylic resin samples with 0.2% in liquid additive form (3A) ended in more flexural power then 0.4% addition (3B) in comparison to different changed groups .The samples with 0.4 % in powder form(2B) had a lowest (1514) Hoda A Rashad and Faten A S Abutaleb E.D.J. Vol. 64,No. 2 flexural strength in comparison to the all groups (p< 0.05). In comparing the color variations (ΔE) comparable to control group, group 3A and group 3B, showed lowest color variations respectively. At the same time group 2Aand 2B ended in highest shade distinction .Conclusion: Set up on the effects of this results, modifying PMMA with Nano silver debris led to lower in flexural strength and shade stability, addition of Nano silver particles in liquid shape was higher than powder form as concerning flexural strength and better color difference and the addition percentage of 0.2 became better than 0.4. Menopausal pride turned into higher and her complain became managed with the new denture.

“…The increase in flexural strength could be attributed to factors such as enhanced interfacial bonding between the fiber and the resin, as a result of the presence of SiC microfiller. 43 Furthermore, the good dispersion of the microfiller in the matrix can offer an additional load-bearing capacity of the matrix and contribute to the observed increase in flexural strength. The decrease in flexural strength at higher microfiller addition might be a result of microfillers agglomeration leading to a higher tendency for matrix cracking.…”

The effects of microfiller addition on the flexural properties of carbon fiber reinforced phenolic (CFRP) matrix composites were investigated. The CFRP was produced using colloidal silica and silicon carbide (SiC) microfillers, 2 D woven carbon fibers, and two variants of phenolic resole (HRJ-15881 and SP-6877). The resins have the same phenol and solid content but differ in their viscosities and HCHO (formaldehyde) content. The weight fractions of microfillers incorporated into the phenolic matrix are 0.5 wt.%, 1 wt.%, 1.5 wt.%, and 2 wt.%. Flexural properties were determined using a three-point bending test and the damage evolution under flexural loading was investigated using optical and scanning electron microscopy. The results indicated that the reinforcement of phenolic resins with carbon fibers increased the flexural strength of the HRJ-15881 and SP-6877 by 508% and 909%, respectively. The flexural strength of the CFRP composites further increased with the addition of SiC particles up to 1 wt.% SiC but decreased with further increase in the amount of SiC particles. On the other hand, the flexural modulus of the CFRP composites generally decreased with the addition of SiC microfiller. Both the flexural strength and flexural modulus of the CFRP did not improve with the addition of colloidal silica particles. The decrease in flexural properties is caused by the agglomeration of the microfillers, with colloidal silica exhibiting more tendency for agglomeration than SiC. The fractured surfaces revealed fiber breakage, matrix cracking, and delamination under flexural loading. The tendency for failure worsened at microfiller addition of ≥1.5 wt.%.

In this study, the carbon fibre reinforced methyl methacrylate resin composite (CF/MMA) toecaps for safety shoes were manufactured to change impact behaviour by incorporation of nanofillers. Different types of nanofillers such as nanotubes (inorganic halloysite, multiwalled carbon nanotubes) and unmodified and organically modified nanoclays (natural bentonite and montmorillonites) were dispersed inMMA composition. The low-velocity impact test with dropweight machine was performed with respect to the nanofiller nature and carbon fibre stacking sequence. It was found that the most influence on the stiffness and impact damage of the CF/MMA nanocomposite toecaps show organic and inorganic nanotubes or unmodified nanoclay (bentonite). Effective amounts of these nanofillers improve the low velocity impact response in 16 % -20 %. Although the influence of nanofillerson CF/MMA composites energy absorption capability at impact energy level of 90 J is negligible, however, theireffect on thesizeof the composite toecaps damage areais considerable.
