Rhino Carbon Fiber Independent Testing/Case Studies

Rhino Carbon Fiber is independently tested by third party vendors to ensure it is the highest quality products available. Please review the test results and an engineering case study to learn how strong Rhino Carbon Fiber is. The results of the testing are below.

Tension Testing Horizontals

DESCRIPTION
Two sets of carbon fiber samples were received for room tempaerture tention testing. They were identified as Rhino® Fiber Horizontals.

MECHANICAL
Two sets of tensile specimens, with a nominal gage width of 1.0 inches, were received already prepared by the client. Prior to testing it was noted that the specimens have uneven gage sections, jagged edges, areas of non-existant fibers (epoxy only), and uneven layering. Testing was performed at room temperature on a servo-hydraulic test stand with guidance from ASTM D3039-08. Specimens were loaded in displacement control at a rate of 0.05 in/min until rupture.

Table 1 (Carbon Fiber Horizontals)

Sample	Ultimate Tensile Strength (PSI)
	Rhino Carbon Fiber
1	48,030
2	54,200
3	44,310
4	46,260
5	51,310

RESULTS
The average ultimate tensile strength for Rhino Carbon Fiber equals 48,822 psi. Through tensile testing we are able to determine that Rhino Carbon Fiber Horizontals are substantially stronger that the competition.

Tension Testing Verticals

DESCRIPTION
One set of carbon fiber samples were received for room temperature tension testing. They were identified as Rhino® Carbon Fiber Verticals.

MECHANICAL
One set of tensile specimens, with a nominal gage width of 1.0 inches, were received already prepared by the client. Prior to testing it was noted that the specimens had uneven gage sections, jagged edges, areas of non-existent fibers (epoxy only), and uneven layering. Testing was performed at room temperature on a servo-hydraulic test stand with guidance from ASTM D3039-08. Specimens were loaded in displacement control at a rate of 0.05 in/min until rupture.

The sample results are presented in Table 01.
Total results from test are presented in Table 02 with comparative results from Fortress Stabilization System’s website (www.fortressstabilization.com/weavetest.php).

Table 2 (Carboon Fiber Verticals)

RESULTS
The average ultimate tensile strength for Rhino Carbon Fiber equals 51,571 psi.
The average ultimate tensile strength for Fortress Carbon Fiber equals 18,136 psi.
Through tensile testing we were able to determine that Rhino Carbon Fiber Verticals are substantially stronger than the competition.

Corner Wall Repair

DESCRIPTION
Two sets of composite samples were received for tensile testing in accordance with ACI 440.3R-04.

MECHANICAL
All samples were conditioned for a minimum of 40 hours at 20 ± 3°C and 50 ± 5% relative humidity. All samples were tested in similar conditions. Five samples were received for tensile testing in accordance with ACI 440.3R- 04 which in turn referred to ASTM D3039. The samples were tested in the as-received condition. After recieving the samples, it was noted that the specimens had uneven and jagged gage sections. Some of the samples showed signs of voids within the weave of the material. The samples were tested on a servo-hydraulic test stand at a crosshead speed of 0.05 millimeters per second.

The sample results are presented in Table 01.

Table 1 (Tensile Results)

Sample	Dimensions (in)	Ultimate Strength (psi)	Modulus (ksi)	Failure Strain
1	0.944 x 0.0470	44200	29400	0.016
2	0.988 x 0.0418	53800	40800	0.014
3	0.988 x 0.0395	32700	36400	0.01
4	0.971 x 0.0358	63900	44200	0.015
5	1.098 x 0.0466	51700	36500	0.015
Average	--	49260	37460	0.014
St. Dev.	--	11600	5560	0.002

RESULTS
All samples far exceeded necessary strength to support walls.

Lap Shear Testing

DESCRIPTION
Two sets of composite samples were received for lap shear testing in accordance with ACI 440.3R-04.

MECHANICAL
All samples were conditioned for a minimum of 40 hours at 20 ± 3°C and 50 ± 5% relative humidity. All samples were tested in similar conditions.

LAP SHEAR TESTING

Five samples were received for lap shear testing in accordance with ACI 440.3R-04 which in turn referred to ASTM D3039. The samples were tested in the same condition that they were received in. After recieving the samples, it was noted that they had uneven and jagged gage sections. The lap area of the samples was uneven and the thickness varied. The samples were then tested on a servo-hydraulic test stand at a crosshead speed of 0.05 millimeters per second.

The sample results are presented in Table 01.

Table 1 (Lap Shear Results)

Sample	Overlap Dimensions (in)	Shear Strength (psi)	Failure Strain
1	1.034 x 5.55	369	Tension Failure
2	1.060 x 6.00	156	Tension Failure
3	0.960 x 5.36	342	Tension Failure
4	1.085 x 5.05	324	Tension Failure
5	1.061 x 5.76	218	Tension Failure
Average	--	282	--
St. Dev.	--	90.7	--

RESULTS
Each of the samples did not fail in the lap shear area.

Structure Reinforcement Modification on Concrete Masonry Unit Wall With Rhino Carbon Fiber Reinforce

A static mixer is placed over a cartridge of concrete crack injection material. The material will then be injected through a surface port and into the foundation crack

Static mixers snap tightly into our surface ports. Surface ports allow the concrete crack injection materials to enter the crack.

Injection of polyurethane concrete foundation crack repair material. All repairs are done from the inside of the basement.

Extremely tight hairline concrete cracks can be injected with a high pressure grease gun.
