Carrera Group is master distributor for GBRacing, the leading manufacturer of race developed crash protection products. GBRacing products are designed, tested and manufactured to the highest standards using best quality materials, so that every product meets or exceeds customers' expectations.

One of the key differences between GBRacing and other crash protection products is the use of Long Glass Fibred Nylon 6.6 based materials across their range of products. Long Glass Fibred Nylon 6.6 compounds not only provide exceptional impact resistance, they also offer an excellent alternative to die-cast metal materials. The table below shows just how much more tensile and impact strength is offered by Long Glass Fibred Nylon 6.6 compared with other commonly used materials. 

Materials Comparison

Type/Grade	Material	Tensile Strength (MPa)	Impact Srength, Izod Notched (J/m)
Acetal Base Resin	Delrin / Acetal	60	80
Acetal 30%	Delrin / Acetal Short Glass Fibre 30%	110	72
ABS Base Resin	Acrylonitrile Butadiene Styrene	46	276
ABS 30%	ABS Short Glass Fibre 30%	97	64
SGFN 30%	Nylon 6.6 Short Glass Fibre 30%	159	80
SGFN 60%	Nylon 6.6 Short Glass Fibre 60%	207	139
CFN 60%	Nylon 6.6 Carbon Fibre 60%	221	69
LGFN 60%	Nylon 6.6 Long Glass Fibre 60%	276	481

One can clearly see from the pellet comparison picture below that the LONG GLASS Fibred Nylon pellets on the right are 4-5 longer than the Short Glass Fibered Nylon materials on the left. The grade of material used is LGFN 60%.

After processing the Long glass fibres are 10-20 times greater in length than conventional short glass fibres, providing:

• Greater than 100% improved impact resistance at any temperature, plus extreme stiffness
   
• Outstanding fatigue performance
   
• Low warpage and good dimensional stability
   
• The long fibres absorb more energy before and after fracture initiates. Fracture crack lines are forced around the fibre ends, resulting in a limited fracture area.

Injection Moulding Process

GBRacing uses injection mounlding as its primary manufacturing process; injection moulded products offer additional built in strength and flexibility compared to conventional machined plastics.

The majority of competitors crash protectors / frame sliders are manufactured from extruded materials, such as Delrin, Nylon etc. These materials are then CNC machined into various shapes. The choice of materials used may indeed be correct for their machining qualities, but not necessarily the best for the application.

As an injection moulded process, GBRacing crash protectors / frame sliders are designed with variable wall sections, and distortion joints. They have an internal, Steel plated tube structure, where the fixing bolt passes through. This enables the 2 part moulding to be joined together, without the rigidity of a solid construction. These design features ultimately allow greater impact absorbtion and distortion within the moulded structure itself. Having an overall effect of reducing the impact forces transmitted to the engine mounting points.

Bolt Specifications

The standard Bolt choice for Frame sliders is A2 Stainless Steel, chosen for it's Elastic Modulus. For Engine Covers it is Class 12.9, chosen for the proven durability and tensile strength. A separate de-embrittlement process is added after plating to reduce bolt shearing. These bolts, washers and lock nuts can be supplied in either our Bright Nickel Secondary Plate (BNSP), or a Blackened Finished Secondary Plating (BFSP) process. The BNSP & BFSP process ensures a virtual rust free product, by adding a layer of copper plating, prior to the surface finish plating.
