Burn Rate:

Sample description: AeroTek® Composite Board material with an average measured thickness of .115″

AeroTek® (1.03″/min)

Azdel Onboard (1.85″/min)

Tensile Strength:

Objective: To evaluate the performance and bond strength of panels before and after accelerated aging cycle

Procedure: 3rd party testing service received eight sets of 2-inch by 2-inch cut-out samples. The samples were construed with RV64021 and the following materials:

MT1 A-E Azdel Onboard composite; Ambient FWT (Max Tensile Strength) – 60.24

MT2 A-E AeroTek® composite; Ambient FWT (Max Tensile Strength) – 67.89

MT5 A-E Azdel Onboard composite; Thermal Cycled + FWT (Max Tensile Strength) – 53.57

MT6 A-E AeroTek® composite; Thermal Cycled + FWT (Max Tensile Strength) – 70.60

Aged Preparation:

Samples MT5 and MT6 were placed into accelerated aging cycle

The parameters for the aging test were as follows:

1) 10 hours at 180°F and 10% Relative Humidity (RH)

2) 2 hours transition to next setting

3) 10 hours at -40°F and 0% RH

4) 2 hours transition to next setting)

5) 10 hours at 100°F and 90% RH

6) 2 hours transition back to 1) setting

The six-step cyclic testing described above was repeated for five cycles. The total time for the aging process was 7.5 days.
