what is the density of carbon fiber composite?
155629
Not enough information provided. The density of any carbon fiber product is based apon the requirements of the product and its use. The amount of polymer to fiber ratio is based on that information.

Iron has a density of 7.86 g·cm−3 and chrome has a density of 7.15 g·cm−3 which would make Iron heavier.

MDF typically has a density of 600-800 kg/m³\n\ntherefore, taking a value of 700 kg/m³ -\n\n1*1*0.006*700 = 4.2 kg/m2\n\nis that near enough?

Most often, especially for low speed applications, it is a matrix of carbon fibers in a foam substrate.  At higher speeds, carbon fiber composites can be used, but radar waves can even be reflected from insulating materials (due to the change in dielectric constant between air and the material).  Many of these things reflect very poorly, though.  Coating the front of your car would not likely help with the local police radar -- however.

If the density is 'd' kg/m^3 then the weight is '9.81d' Newton. [remember weight is force]

density is mass / volume. so 514 grams / 500 mL sample

It would be because of the density of the matter..

The density of dry loose gravel regardless of size is on average about 90 to 105 pounds per cubic foot. This assumes a fairly consistent size. If the gravel is a mixture of large and very fine material then it will be some what higher because the fine grains will fill in between the larger pieces. \n\nAny granular material that is evenly graded (all pieces about the same size) will have the same degree of void space between granules. It calculates to around 30% (I don't remember the exact number but you can calculate it you like). Most sand and gravel is made of the same ground up rock, therefore density of the individual grains or pieces is the same. With 30% of any cubic foot the same and the density of the grains the same, sand or gravel will have the same density.

You could consider reporting on the soon to be widespread use of CF (carbon fiber) to build giant airplanes and automobiles.  CF weighs much less than aluminum or steel and is stronger.  Reducing weight will save on fuel and will help enable the oncoming hydrogen/fuelcell cars.  CF also must be used in the larger wind turbine blades (about 300 ft in diameter) because it is light enough yet stiff enough to avoid bending and hitting the tower.  Also carbon nanotubes will provide the strongest CF if the cost can be reduced.

Saturn. It's density, if I remember right is something on the order of .97 gm/cc. I remember seeing an illustration in an old book of Saturn floating in a sea.

we know that mass = volume * density\nin the first case, mass = 278.1g\nvolume of the cube = 3*3*3 = 27 cm^3\ntherefore density = mass/ volume\n density of steel = 278.1/27 = 10.3\nThrefore the mass of 1 cm^3 of steel= volume * density\n                                    = 1 * 10.3\n                                    = 10.3 g\n\nNote: denstiy of any material is always a constant- it is an intrinsic property of the material. It is important to get these concepts right when you study them so that you can have a good foundation for higher studies. Please promise me that once you understand how to do this problem, you will try it on your own. Thanks. goodluck

Density is a physical property of matter that describes the degree of compactness of a substance, in other words, closely packed together the atoms of an element or molecules of a compound are. The more closely packed together the individual particles of a substance are, the more dense that substance is. Since different substances have different densities, density measurements are a useful means for identifying substances. \n\nFor example, how could you distinguish a metric ton of feathers versus a metric ton of bricks if you could not see them? \n\n    \n\nOne metric ton of either feathers or bricks will have an identical mass of 1,000 kilograms (one metric ton). However, a metric ton of feathers will occupy a volume of almost 400 million cm3(about the size of four tractor trailer trucks), while a metric ton of bricks will occupy only one half million cm3 (about the size of a large screen TV). The bricks are denser than the feathers because their mass is packed into a smaller volume. This relationship between the mass and volume of a substance is what defines the physical property of density: \n\nDensity = Mass/Volume \n\nDensity is an intensive property of matter that is defined as the ratio of an objects mass to its volume. Mass is the amount of matter contained in an object and is commonly measured in units of grams (g). Volume is the amount of space taken up by a quantity of matter and is commonly expressed in cubic centimeters (cm3) or in milliliters (ml) (1cm3 = 1 ml). Therefore, common units used to express density are grams per milliliters (g/ml) and grams per cubic centimeter (g/cm3). \n\n\nLet's look at an example. A typical brick has a mass of 2,268 g and occupies a volume of 1,230 cm3. The density of the brick is therefore: \n\n\n\n2,268 g/1,230 cm3 = 1.84 g/cm3 \n\nDensity is an easy concept to confuse. For example, many items that we commonly think of as ‘light’ or ‘heavy’ do not have different masses, but they do have different densities. Look at the table below for examples of the densities of common substances.
