Objectives: This In-vitro study was designed to compare the Impact strength and Residual monomer content of conventional and high impact types of denture base resins polymerized by Compression and Injection molding technique with short curing cycle. Materials and Methods: Forty samples were made (twenty from each technique)in the dimension of 60 × 10 × 3 with 2 mm notch on the thickness side. T...
The mechanical properties and morphology of polypropylene/wood flour (PP/WF) composites with different impact modifiers and maleated polypropylene (MAPP) as a compatibilizer have been studied. Two different ethylene/propylene/diene terpolymers (EPDM) and one maleated styrene-ethylene/butylene-styrene triblock copolymer (SEBS-MA) have been used as impact modifiers in the PP/WF systems. All three...
Health impact assessment (HIA) on a strategic level focuses on the broad determinants of health. However, the evidence with regard to the health impacts is often necessarily 'soft'. The example of a health impact review on national housing policy in the Netherlands shows that HIA can be effective even in the absence of hard data. Strategies used to overcome the problem of not having hard data a...

in the current study an experimental/statistical approach addressing key mechanical properties (compressive, tensile and flexural strength) and impact resistance of such new fibers with inclusion of different volume of polyphenylene sulfide (pps) fibers has been carried out on 288 specimens. results from this study revealed that compressive, tensile and flexural strength exhibit a good fit with...
Glass fiber reinforced polymer composites are one of the most widely used composite materials. The addition of Coal ash to polymer matrix dramatically increases the overall mechanical strength of the composite material as compared to the polymer composite. In view of this, a method is proposed for mixing coal ash powder (size 52-75 μm) into resin and Ash reinforced polymer composites are fabric...
In this study, the influence of different weight percentages of glass fiber (GF) reinforcement on the mechanical properties of nylon (PA6) composite is investigated. Test specimens of pure nylon, 95% nylon + 5% GF, 90% nylon + 10% GF, 85% nylon + 15% GF and 80% nylon + 20% GF are prepared using an injection molding machine. In the experiments, tensile tests and impact tests are carried out. The...
