Carbon fibre-reinforced carbon (aka carbon–carbon‚ abbreviated C/C) is a composite material consisting of carbon fibre reinforcement in a matrix of graphite. It was developed for the nose cones of intercontinental ballistic missiles‚ and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter. It has been used in the brake systems of Formula One racing cars since 1976; carbon–carbon brake discs and pads are a standard component of Formula One brake

Stress relaxation is an intrinsic property of a material‚ in which‚ the material decreases the applied load held at constant strain with passage of time. The total strain remains constant but a fraction of the elastic strain transforms into plastic strain [3]. Stress relaxation characteristics of a material become vital when designing mechanical fasteners‚ riveted or bolted assemblies‚ shrink or press-fit components‚ solderless electrical connectors‚ etc. Moreover‚ stress relaxation data could be

C. Central Composite Design As PBD considers only main effects and ignores the interactions among the factors‚ therefore‚ a new design is required. Central composite design (CCD) is type of experimental design‚ which was first described by Box and Wilson (1951). Nowadays it is widely used in response surface methodology (RSM; discussed in the next section of the review) for building a second order (quadratic) model for the response variable without using a complete three-level factorial experiment

an overview of the smart materials. The various types of smart material are also presented in this paper. To get the clear idea about the smart materials‚ its definition and types are explained briefly. Some of the types of these include piezoelectric materials‚ magneto-rheostatic materials‚ electro-rheostatic materials‚ and shape memory alloys piezoelectric‚ Varieties of smart materials already exist‚ and research is being carried out extensively to derive new materials.

[pic] INTRODUCTION Materials are an important determinant of the total cost of production‚ as it constitutes around 50% to 60% of total cost. Materials as our input in production system are receiving attention of the industrialists from 1900 onwards. Since the beginning of 20th century‚ materials have been occupying a place of importance among the M’s of Materials‚ Money‚ Man‚ Machine and this will continue to be so in the years to come. Materials management is one of the areas covered

Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

Insulation has been used to keep heat in and keep out air for a long time. Fiberglass insulation can be described as glass fibers combined with other materials (Sheppard‚ 2012). It has different materials in it that help the material insulate. The material is also chosen very commonly because of the cost efficient price on this insulation (Thermaxx Jackets‚ 2011). In an overall view‚ fiberglass insulation is chosen by more people from the efficient and inexpensive price compared to the other insulations
