Automotive Carbon Fiber Applications

Carbon fiber is a superior mechanical properties of new materials, 1/4, tensile strength carbon fiber resin composite material is less than the proportion of its steel in 3500Mpa more generally, it is 7-9 times stronger than steel, tensile modulus of elasticity of 23,000 ~ 43000Mpa also higher than steel, but carbon fiber materials only exhibit high strength along the fiber axis direction, but poor impact resistance, easy to damage, so when manufacturing becomes structural components, often using their pull-resistant lightweight advantages while avoiding side impact do bear some of the general density of carbon fiber is 1750 kg / cubic meter, this density is widely used in large aircraft, such as Airbus A350 and A380, Boeing 787 all use of carbon fiber composites to reduce fuel consumption the amount of addition of large wind turbine blades, car, high-end bicycle body are an important factor in the demand for carbon fiber composite material increases.

Currently carbon fiber material in civilian production cars, especially the mid-range product applications are very wide, many manufacturers have begun to offer gadget carbon fiber material, such as rear-view mirror housing, interior door panels, door handles, gear lever, racing seats, air packages, etc., while the original bit installation to the engine compartment bellows, intake manifolds carbon fiber modification parts is variety.

Each carbon fibers by the thousands more tiny carbon fibers composed of a diameter of about 5-8 microns in atomic level with graphite carbon fiber is very similar, is composed of a layer of carbon atoms arranged in a hexagonal pattern composed Both differences that the link between the layers of graphite crystal structure, loose link between its layers, while the carbon fibers are not crystal structure, the interlayer coupling is irregular.

From the paper as soft to steely tough qualitative change process; by pressing in a mold staggered stacked CFRP fiber direction; the use of an epoxy adhesive layer by layer multilayer diced CFRP stand together, this process requires with 5-10 layers or more of CFRP, bonded into a thicker version of CFRP. In this case it's flexibility has been very poor, almost with a rigid material almost.

Solid feel and plastic almost, but has the strength and toughness of the steel is generally carbon fiber components, not only to help the vehicle effectively lose weight, but also because of its expensive properties and become a symbol of luxury. In Ferrari, Lamborghini, Pagani, represented Italian supercar surely we are very familiar with, in order to pursue lightweight, almost regardless of the cost due to the manufacturing process, so in the car and even large-scale application of carbon fiber components of the vehicle using a carbon fiber material is totally not a problem.

In the civil automotive sector, Mercedes-Benz tries to apply carbon fiber material as the crumple zone first in the SLR McLaren has been applied. Showed a minaret-like carbon fiber crumple column by the numerous root thick carbon fibers through the woven, although the structure is still very hard, but it can be broken in the design of the frontal collision into a thousand tiny pieces, to absorb a lot of energy, and the debris will not harm people, it is very similar to the broken car glass of principle.
