Carbon Fiber Laminate Density

Carbon fiber used in mclaren 650s trim in the steering wheel.

Carbon fiber laminate density.

Carbon fiber composite design guide. Carbon fibres exhibit generally superior performance in tensile compressive and flexural properties as well as fatigue resistance. In other words it takes half as much carbon or aramid fiber to get the same. Weight per unit volume or density of carbon fibre kevlar and e glass.

Carbon laminate density is so low it even beats the lightest structural metal magnesium which has a density of 1 8 g cc. Density 0 058 lb in3 1 60 g cm3. Carbon fiber laminate for structural strengthening product description sika carbodur s is a pultruded carbon fiber reinforced polymer cfrp laminate designed for strengthening concrete timber and masonry structures. The denser a material is the heavier it will feel for an equal sized chunk.

Laminate thickness mm fiber mass content material requirements for simple laminates. From the mechanical properties of the composite listed in table 16 2 and the shear lag model the axial modulus of as4 3501 6 carbon epoxy cross ply laminate 0 90 2 s was calculated as a function of matrix crack density from equation 16 24 and compared with the experimental data as well as the results without the effects of residual thermal. Nevertheless the table below is shown for comparison purposes to help the end user get a better understanding of the properties of the more common laminate designs. You would find that the glass composite is almost twice as heavy as the kevlar or the carbon fiber laminates.

Best tensile strength flexural modulus heat distortion temperature and linear expansion compared with other epoxy laminates. Density matrix g cm. As an example a plain weave carbon fiber reinforced laminate has an elastic modulus of approximately 6 msi and a volumetric density of about 83 lbs ft 3. Because there are literally thousands and thousands of options when it comes to carbon fiber it is impossible to list and explain all of the potential properties of carbon fiber.

Thus the stiffness to weight for this material is 107 ft. The purpose of this design guide is to provide general information and specifications on graphite carbon fiber composite materials and some guidelines for designing lightweight high performance products with graphite composites. Also excellent interlaminar and in plane shear strengths.
