The First Test Lab Dedicated to Additive Manufacturing

SPECIALIZING IN THE VALIDATION, QUALIFICATION AND CERTIFICATION OF
SPACE FLIGHT MATERIAL, LAUNCH VEHICLES AND SATELLITE TECHNOLOGIES

Launch Sooner

ASTRO serves as a partner for aerospace primes and advanced space companies contributing to the incorporation of advanced materials and intelligent engineering into complex flight hardware.

Along with our customer base, we work hand-in-hand with the industry’s raw material providers, international standards developers and AM research institutes to engage in the meticulous analysis of the properties of novel super alloys and the innovative technologies that fabricate with them. Throughout this process, we support progress in AM development and production methodologies through qualification and certification pathways towards the industrialization and democratization of additive.

NOBODY WANTS TO FALL BACK TO EARTH

With a rich legacy in the testing of flight hardware, our team has played a pivotal role in risk mitigation and prevention following catastrophic events in aerospace history.

From breaking landing legs on rockets and wheels on Martian rovers, to dismantling foam insulation on the Space Shuttle and destroying lunar components, our experience in failure analysis spans over three decades.

We firmly believe that this history of navigating orbital challenges has uniquely positioned us with a comprehensive understanding of acceptance criteria through testing the physical properties of materials under both dynamic and static forces. With a focus on additive manufacturing, we have paired our practices with further chemical and metallurgical analysis to create a full scope approach to conformance.

Testing Services

We focus on the two most favored methods of mechanical testing : Tensile + Fatigue
We can perform Tensile & Fatigue tests in Environmental Test Chambers for Cryogenic and Elevated Temperatures

 

Our fleet of testing machines consist of Instron and MTS stands with varying capabilities.
We have the option of various load cells and increasing pound-force to meet hundreds of specimen testing requirements

 
 
 

  • Tensile testing is used to determine the behavior of a sample while an axial stretching load is applied. Tensile testing is used to determine the maximum load (tensile strength) that a material can withstand.

    Our tensile testing machines utilize state-of-the-art digital instrumentation to report the ultimate tensile strength, maximum elongation, and reduction of the area of a material. Based on your requirements, testing results may include:

    • Maximum Load, Deflection and Work

    • Stress and Strain

    • Young's Modulus: elastic limit, yield point, yield strength and elongation

    • Poisson's Ration: lateral strain, longitudinal strain

  • Fatigue testing is used to characterize material properties behavior during cycling loading. It measures how cyclic forces will affect a product or material over time, using varying loads, speeds and environmental conditions to create predictive patterns for material behavior. Based on your requirements, results show a fatigue strength curve, which demonstrates the material’s resistance to cyclic loading over varying stress levels.

    Our fatigue testing capabilities include:

    • Low Cycle Fatigue (LCF)

    • High Cycle Fatigue (HCF)

    • Room & Elevated Temperature

  • We can perform Tensile & Fatigue tests in Environmental Test Chambers for Cryogenic and Elevated Temperatures

    • Tension/Compression

    • Shear Properties

    • Fracture Toughness

    • Impact Testing (Charpy, IZOD)

    • Universal Hardness (Rockwell, Brinell)

    • Creep and Stress Rupture

    • Bend Testing

    • Coefficient of Thermal Expansion
