Performance

LOAD TESTING

We instructed an independent testing company to measure the deflection of our carbon brace and compare that against the OEM CSL brace. Both braces were mounted to a custom made jig to which both tensile and compressive loads were applied. The maximum load applied was 10kN.

G1 to G3 are the deflection measurement points in a horizontal plane. The point G4 is the deflection in a vertical plane at the location of G1.

Summary of results at maximum load:

Point G1 at 4.8kN: Eventuri = 58 microns : OEM = 121 microns
Point G2 at 6kN: Eventuri = 85 microns : OEM = 291 microns
Point G3 at 10kN: Eventuri = 613 microns : OEM = 1291 microns
Point G4 at 10kN: Eventuri = 2503 microns : OEM = 3702 microns

Summary of results at maximum load:

Point G1 at 10kN: Eventuri = 83 microns : OEM = 181 microns
Point G2 at 10kN: Eventuri = 1007 microns : OEM = 1051 microns
Point G3 at 6kN: Eventuri = 396 microns : OEM = 300 microns
Point G4 at 10kN: Eventuri = 4210 microns : OEM = 6922 microns

Two car engine brace samples were received in the laboratory on 10 October 2025 :
The samples were given our laboratory reference numbers E684 & E685. The samples were described as follows:
Sample E684: Aluminium engine brace measuring approximately 1200mm maximum length and 530mm width. The thickness was in the range 16-30mm.

Sample E685: Carbon Fibre engine brace approximately 1200mm total length and 510mm width. The thickness was in the range of 25-35mm.

The samples included several fixings points located in 3 areas. These were on the left and right ends (ends A & B) which included 2 fixing holes at each end while the front side (Side B) included 3 fixing holes.

A test rig was manufactured to accommodate the test samples, such that they were fixed in a horizontal plane to a steel plate which was attached to a rigid test bed. The fixing holes were used to bolt the samples to the steel plate.

The testing was affected by fixing two points while applying a lateral load to the third point. At each point, the load was applied in two directions, a pull test away from the brace and a push test into the brace.

The deflection of the brace was measured at 4 locations.

For each test, the load was applied incrementally up to a load of 10kN. The deflection of the samples was measured at 4 points as.
