Pros and Cons of Common Body Kit’s Materials: ABS, Carbon, Polyurethane and Fiberglass

The desire to own a car that will be noticeably different from the production model is simply ineradicable for many car owners. Thanks to the external tuning body kit and you have a pretty wide selection. You should decide on the material for its manufacture. It must satisfy the following requirements:

  • Provide the necessary strength and rigidity of the structure.
  • The material should have a low density, be light and affordable.
  • Have good adhesion characteristics in relation to paints.
  • Have the ability to restore their geometry after insignificant deformations.

1. ABS Body Kit

ABS Body Kit

ABS is a form of impact-resistant plastic based on acrylonitrile with added styrene and/or butadiene. ABS plastic is quite popular and is used in various fields – in the manufacture of furniture, household appliances, and of course, automotive parts. Domestic manufacturers of car body kits use this material, perhaps more often than others.

  • Low cost when compared with polyurethane and even more carbon fiber.
  • Good impact resistance with good flexibility, which allows it to withstand minor deformations, returning to its original shape.
  • Good adhesion characteristics.
  • A slight deviation from the optimal manufacturing technology, as well as violations of the chemical composition, cause a sharp increase in fragility at negative temperatures.
  • Weak resistance to heat (corrugation appears at 90 degrees and above).
  • Insufficient resistance to aggressive substances.

2. Carbon Body Kit

Carbon Body Kit

Carbon is a modern composite material, a member of the extensive family of carbon fiber reinforced plastics. The technology of manufacturing carbon plastics is characterized by the use of carbon elements as a filler, which is glued together with resins. Carbon has the best weight-to-strength ratio, which has led to its widespread use in the design of carbon e bike and racing cars, including Formula 1.

  • Original easily recognizable appearance.
  • Relatively low weight (40% less than steel, 20% less than aluminum).
  • With good strength.
  • Higher cost than ABS plastic or fiberglass.
  • Low tensile index, which makes it fragile and susceptible to directional mechanical shock loads.

3. Polyurethane Body Kit

Polyurethane Body Kit

The chemical formula of polyurethane includes a chain of macromolecules with inserts of the -NH-CO-O- type, representing a group of urethanes, which gave the name to the material. Currently, two varieties of polyurethane: rubberized and foamed.

3.1 Rubberized Polyurethane Body Kit

  • Characterized by a very high-quality indicator for almost all important criteria.
  • Excellent impact resistance.
  • The inclusion of rubber fillers in the material makes it elastic and flexible;
  • An excellent combination of strength and flexibility allows polyurethane products to withstand rather serious mechanical stress without collapsing, and in case of serious deformations – return to their original shape.
  • It is very difficult to break a product made of this material.
  • High accuracy of the casting of body kit parts.
  • Has good adhesion to hold paint.
  • High cost

3.2 Foamed Polyurethane Body Kit

  • In quality, it is slightly inferior to the rubberized counterpart.
  • High impact resistance.
  • Usually, with no installation problems.
  • EP thickness is greater than other materials, with low weight and high density.
  • Insufficient resistance to fracture.
  • High cost.

4. Fiberglass Body Kit

Fiberglass Body Kit

Made of fiberglass by resin impregnation, it is considered one of the most demanded materials in external and internal car tuning.

  • The most affordable cost.
  • Its quality is not inferior to either polyurethane or ABS plastic.
  • Lightweight.
  • Ease of Processing.
  • Good flexibility.
  • Manufacturing accuracy is inferior to other materials. During installation, it requires careful adjustment of the body kit;
  • Fiberglass is considered a toxic material due to the presence of epoxy resins in its composition. When working with it, compliance with TB is required (it is recommended to use a respirator).
