چکیده

JCO/DECEMBER 2005 T lingual technique is considered to be one of the most difficult, requiring extended treatment times and often achieving less-than-satisfactory results. Firstand third-order tooth movements are complicated by the variable lingual tooth anatomy.1 Torque control is also more problematic; with the reduced interbracket distance, even small variations in bracket height can have a substantial effect on torque. These factors have led to the development of various indirect bracket-positioning methods.2 A new, inexpensive, self-ligating bracket overcomes many of the drawbacks of lingual treatment while still providing high-quality results.3,4 Instead of a rectangular slot, the Philippe 2D lingual bracket* has two wings on the lingual surface to contain the archwire (Fig. 1). Brackets are directly bonded to the lingual surfaces without an indirect setup. A progression of round nickel titanium archwires can be used to ensure

Creep Behavior of Basalt and Glass Fiber Reinforced Epoxy Composites

The creep behavior of basalt fiber reinforced epoxy (BFRE) and glass fiber reinforced epoxy (GFRE) composites was studied through tensile testing at high temperature. To study the effect of reinforcing epoxy, the micro glass powder (MGP) was added at various volume percentage into the epoxy resin in BFRE composites. The initial strain for all the specimens were evaluated and compared with each ...

MECHANICAL CHARACTERIZATION AND ANALYSIS OF RANDOMLY DISTRIBUTED SHORT BANANA FIBER REINFORCED EPOXY COMPOSITES

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...

Fiber reinforced plastic composites using recycled materials

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

Meso-scale Modeling of Tension Analysis of Pure and Intra-ply Hybrid Woven Composites Using Finite Element Method

One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...
