Carbon Fiber Material Properties

Carbon fibers or carbon fibres alternatively cf graphite fiber or graphite fibre are fibers about 5 to 10 micrometers 0 00020 0 00039 in in diameter and composed mostly of carbon atoms.

Carbon fiber material properties. Onyx our flagship composite base material is a nylon mixed with chopped carbon fiber that yields accurate parts with impeccable surface finish. Carbon fibers have several advantages including high stiffness high tensile strength low weight high chemical resistance high temperature tolerance and low thermal expansion. Carbon fiber can have a broad range of cte s 1 to 8 depending on the direction measured the fabric weave the precursor material pan based high strength higher cte or pitch based high modulus stiffness lower cte. Each property range of values reported is minimum and maximum values of appropriate matweb entries.

Carbon fiber material comes in a variety of raw building blocks including yarns uni directional weaves braids and several others which are in turn used to create composite parts. Composite materials engineering specialists in carbon fibre in liquidation july 2009 for financial legal enquiries the liquidators details can be found on the home page the contact page is for technical enquires only. Carbon fiber fabric is a strong fiber that is light in weight and has long strands interwoven together so that it forms a fabric like structure. The two different equations governing the net elastic modulus of composite materials using the properties of the carbon fibers and the polymer matrix can also be applied to carbon fiber reinforced plastics.

The properties of a carbon fiber part are close to that of steel and the weight is close to that of plastic. However carbon nanotubes are agglomerated because of their high aspect ratio the ratio of length to diameter and superficial energy 54 which causes the properties of the composite to drop sharply. Few materials have the versatility of onyx. Mechanical properties of carbon fibre composite materials.

Properties of carbon fiber composites are dependent on the direction and the properties shown above are only valid for one direction typically referred to as the longitudinal direction. Today there are more than a million onyx parts in the field transforming manufacturing. 7 5 can be used as a carbon fiber filler to increase electrical conductivity and mechanical properties of the composite. This property data is a summary of similar materials in the matweb database for the category epoxy carbon fiber composite.

The properties of cfrp depend on the layouts of the carbon fiber and the proportion of the carbon fibers relative to the polymer. This data and information shown should only be used for comparison purposes it should not in any way be used for design purposes as actual properties will vary based on many factors including.
