Mechanical Properties of Polymer Composite Materials
In this paper, composite materials and its properties are discussed in detail. It is also discussed their importance and replacement for metals because of their properties like low weight, corrosion resistance etc. Now-a-days, there is a great importance of usage of these materials in various applications in all Engg. Fields. The paper also brings out the manufacturing techniques and costs invo...
متن کاملImpact of Packing and Processing Technique on Mechanical Properties of Acrylic Denture Base Materials
The fracture resistance of polymethylmethacrylate (PMMA) as the most popular denture base material is not satisfactory. Different factors can be involved in denture fracture. Among them, flexural fatigue and impact are the most common failure mechanisms of an acrylic denture base. It has been shown that there is a correlation between the static strength and fatigue life of composite resins. The...
متن کاملMechanical and thermal properties of polyamide versus reinforced PMMA denture base materials
PURPOSE This in vitro study intended to investigate the mechanical and thermal characteristics of Valplast, and of polymethyl methacrylate denture base resin in which different esthetic fibers (E-glass, nylon 6 or nylon 6.6) were added. MATERIALS AND METHODS FIVE GROUPS WERE FORMED: control (PMMA), PMMA-E glass, PMMA-nylon 6, PMMA-nylon 6.6 and Valplast resin. For the transverse strength test...
متن کاملShear Bond Strength of Acrylic Denture Teeth to PMMA and Polyamide Denture Base Materials
Introduction: Detachment of denture teeth from denture base is one of the most common reasons for costly denture repairs .This study aimed at evaluating the bond strength of an acrylic denture tooth to polyamide injection-molded thermoplastic denture base material compared with three conventional polymethylmethacrylate (PMMA) denture base resins. Materials and Method: A total of 40 acrylic dent...
متن کاملProperties of Composite Materials
strength, flexural modulus, and contraction stress of one orthodontic composite and two flowable composites. Orthodontic brackets were bonded to 45 human maxillary premolars with the composites Transbond XT, Filtek Z-350 flow and Opallis flow and tested for shear bond strength. For measurement of flexural strength and flexural modulus, specimens were fabricated and tested under flexion. For the...
