Abstract 

Five lots of high-energy gun propellants were tested in uniaxial compression 

at temperatures of 21°, 63", and -32 "C. The materials were taken to -60% strain 

using a deformation rate of 1.5 m/s. The stress at failure, strain at failure, 

compressive modulus, failure modulus, incremental energy density, and the 

fracture assessment values were recorded for each test.

1. Introduction 

The following is the U.S. Army Research Laboratory's (ARL's) report of 

the material test systems (MTS) servo-hydraulic tester (SHT) high-rate 

mechanical response of one lot of Aerojet 3744 lot no. 8194D, and three lots of 

Thiokol lot no. JA-1835-2-01, JA-1835-2-02, and JA-1835-2-03. The Aerojet and 

Thiokol materials are Future Combat System candidate (Figure 1) gun 

propellants (test sets 65-80 Fiscal 01). A production lot of JA2 lot no. HCL93- 

J014-001 was also tested using similar test conditions for comparative purposes. 

Figure 1. MI Abrams tank with 120-mm gun. 

2. Background 

ARL received four lots of Aerojet and Thiokol gun propellants (Figure 2) from 

Ms. Thelma Manning of the U.S. Army Armament Research, Development, and 

Engineering Center (ARDEC). The Aerojet next-generation high-energy 

propellant was manufactured in a mixer and extruded thermally into a 

solid-sheet configuration. The sheet material had a thickness of -1.3 m. 

Several sheets from the lot of experimental gun propellant were shipped to Dr. 

Robert Lieb of ARL. The Thiokol lots were extruded into solid-stick 

configuration and also shipped to Dr. Lieb. Also, a production lot of JA2 

granular propellant was procured from Aberdeen Proving Ground (APG) for 

comparison testing. All of these materials were tested during August 2001 for 

high-rate uniaxial compression mechanical response evaluation.

under each test condition (Figure 3). Strain rates of 125.0 s-1 were achieved. The 

specimens were taken to failure at ambient pressure to -50% end strain while 

conditioned at temperatures of 21°, 63", and -32 "C. The stress at failure, strain 

at failure, modulus, failure modulus, incremental energy density, and fracture 

assessment value were recorded for each test. The average values achieved from 

the tests are listed in Table 1. 

4. Conclusions 

One lot of Aerojet 3744 lot no. 8194D, three lots of Thiokol high-energy gun 

propellants, and one production lot of JA2 were tested for mechanical response 

at ambient pressure while conditioned at 21°, 63", and -32 OC. The materials 

were tested in uniaxial compression to -50% end strain using a deformation rate 

of 1.50 m/s.

Young's modulus values showed some "softening" as a result of the higher 

testing temperature, as would be expected. The stress/strain plot (Figure 6) 

shows all lots able at sustaining load. The tested specimens (see Figure 5) again 

showed very minimal axial fracture and deformation. 

At -32 "C, the tested specimens (see Figure 5) suffered moderate amounts of 

axial and shear fracture; however, the core area of the tested specimens remained 

mostly whole. Note the stress/strain plot at - 32 "C (Figure 7) shows the JA2 lot 

able at sustaining load and workhardening up to 50% strain and thus the only lot 

yielding a positive failure modulus value. The Thiokol lots showed more 

strength at yield than the Aerojet lot. 

Overall, each material's mechanical response at 21" and 63 "C was quite good. 

At -32 "C, the JA2 lot was clearly the better material, followed by the Thiokol 

and Aerojet lots.

aThe failure modulus (slope of the curve after failure) has been added. Generally, the lower the 

value, the worse the material (i-e., negative value indicates the material is unable to sustain load). 

A positive value indicates a positive failure slope (i.e., the material is better able to support load 

after failure). 

bThe incremental energy density (IED) value reported is the amount of energy per unit volume 

absorbed at 25% strain; this includes a portion of the area located beneath the stress/strain curve. 

qhe tested specimens were assigned a fracture assessment value (FAV). The values range from 0 

(no observed fracturing) through 9 (severe fracturing observed). The type of fracture was also 

characterized using the following methodology: A = axial fracture, S = shear fracture, 

B = barreling/deformation, R = radial splitting (i.e., 9A indicates the tested specimens showed a 

severe amount of axial fracture).

AGENCY REPORT NUMBER 

Five lots of high-energy gun propellants were tested in uniaxial compression at temperatures of 21°, 63O, and 

-32 OC. The materials were taken to -60% strain using a deformation rate of 1.5 mk. The stress at failure, strain at 

failure, compressive modulus, failure modulus, incremental energy density, and the fi-acture assessment values were 

recorded for each test.
