Material Logic (DARPA BAA 10-64) - Frequently Asked Questions

1) What is the "Material Logic" opportunity?

Material Logic is a DARPA Defense Sciences Office research opportunity (DARPA BAA 10-64) focused on developing new material systems that go beyond conventional structural and protective materials used in military vehicles, aircraft, ships, and buildings.

2) What problem is DARPA trying to solve with this program?

DARPA is targeting the challenge that modern military platforms operate in harsh, dynamic environments where shock loads and vibrations can change rapidly and unpredictably. These changing stresses can reduce performance, damage components, and shorten service life. Traditional materials typically do not adjust their behavior as conditions change.

3) Why are conventional materials not enough for these environments?

Many existing materials are designed around a fixed set of properties and are often optimized primarily for extreme stiffness. While stiffness can help in certain scenarios, it can come at the expense of vibration mitigation and survivability across a broader range of load cases. In dynamic environments, a single "locked-in" material response can be a limitation.

4) What does DARPA mean by "adaptive" material systems?

In this opportunity, "adaptive" materials are material systems that can change their mechanical response as conditions change, rather than remaining fixed in one behavior. The intent is to enable structures to tune how they respond to different loading environments over time.

5) What mechanical properties is DARPA specifically looking to combine?

DARPA highlights the need for material systems that can achieve high stiffness and high damping simultaneously, while also providing a meaningful adaptive dynamic range. This combination is emphasized as a central technical goal of the program.

6) Why is combining high stiffness and high damping important?

Stiffness helps maintain structural integrity and precise performance, such as keeping alignment, preventing excessive deflection, and supporting loads. Damping dissipates energy to reduce vibrations and shock transmission, helping protect equipment and occupants and reducing fatigue-related damage. The program is aimed at material concepts that deliver both capabilities together, rather than trading one for the other.

7) What does "adaptive dynamic range" mean in the context provided?

Based on the description, adaptive dynamic range refers to how meaningfully the material system can shift its mechanical response as operating conditions change. The program is positioned around systems that are not confined to a narrow set of behaviors, but can adjust across conditions on demand.

8) What kinds of applications does DARPA mention for these materials?

The opportunity references military vehicles, aircraft, ships, and even buildings. The broader vision is platform and infrastructure structures that can tune properties in real time to match mission needs and environmental conditions.

9) What types of loading conditions are motivating this research?

The announcement emphasizes rapidly changing and unpredictable shock loads and vibrations. It also notes potential operating scenarios that include vibration, blasts, impacts, and other transient loads where a more dissipative response could improve survivability and reduce damage.

10) What is the anticipated payoff if the program is successful?

DARPA signals that success could enable military platforms and buildings that continually tune their properties in real time. For example, a structure might be rigid when precision and load-bearing are critical, then shift to a more energy-dissipative response when encountering vibrations or transient shock events, and potentially shift back again as conditions change.

11) Is this opportunity focused on incremental improvements to existing materials?

No. The description characterizes Material Logic as foundational science and technology research and development aimed at pushing beyond conventional materials, rather than incremental improvements to current material solutions.

12) What funding category or program classification is referenced?

The opportunity is described as a discretionary funding opportunity under CFDA 12.910, identified as Research and Technology Development.

13) Is cost sharing required?

No cost-sharing requirement is indicated in the provided description.

14) What award instruments might DARPA use for this opportunity?

DARPA indicated multiple potential award instruments, including cooperative agreements, grants, other procurement contracts, and related mechanisms.

15) Who is eligible to apply?

Eligibility is described as broadly open (unrestricted) to any type of applicant, subject to any specific clarifications that may be stated in the full BAA text.

16) Where are the full technical and submission requirements located?

The full technical and submission requirements are provided in the attached solicitation document referenced as DARPA BAA 10-64.

17) When was the announcement posted?

The announcement was posted on May 24, 2010.

18) What was the closing date for submissions?

The original and current closing date listed was July 7, 2010.

19) What does it mean that the opportunity was "archived"?

The listing indicates it was archived on August 6, 2010, which typically signals that the public posting is no longer active for new submissions under that announcement as of that archive date.

20) Who is the point of contact mentioned for solicitation access issues?

DARPA listed a BAA Coordinator as the point of contact for access issues related to the solicitation.
