About this file
This document is a set of questions and responses related to a federal contract opportunity for the Advanced Composite Development Challenges (ACDC) program.
The key details are:
- The ACDC program seeks weight-efficient methods for improving the interlaminar mechanical properties of existing continuous carbon fiber reinforced polymer (CFRP) laminates that are integrable with existing lamination production processes. This includes continuous fiber reinforced thermoplastics as a viable alternative.
- Offerors are not required to provide a specific baseline fiber/resin system, as the baseline should be dependent on the proposed technology to isolate the effect of the proposed interlaminar enhancement. Offerors must propose baseline metrics relating to the technical objectives and substantiate expected performance improvements.
- Examples of potentially suitable metrics are provided in the ACDC SORE Task 3.2, and offerors should either include coupon testing per Task 3 or provide a TRL Substantiation Report.
The related federal contract opportunity is solicitation number W911W624R0002 for the Advanced Composite Development Challenges (ACDC) program, issued by the Department of the Army Materiel Command Contracting Command at Redstone Arsenal.

Ques�ons and Responses
W911W624R0002 0002 01
Ques�on 01 Received 03 May 2024
Sec�on 2 "Research Opportunity Descrip�on" paragraph 1 - "ACDC seeks weight-efficient methods for improving the interlaminar mechanical proper�es of exis�ng con�nuous CFRPs that are integrable with the exis�ng lamina�on produc�on processes of two or more exis�ng composite material systems."
Please clarify that only con�nuous carbon fiber reinforced polymer (CFRP) laminate structures, i.e.
thermosets, are in scope for this solicita�on. Thermoplas�cs are viable alterna�ves, but these appear to be out of scope, correct?
Government Response Ques�on 01, 08 May 2024
Con�nuous fiber reinforced thermoplas�cs are considered a type of carbon fiber reinforced polymer (CFRP) and they are in scope; however, any proposed performance improvement should not be the result of changing the fiber/resin system (e.g. changing a thermoset matrix baseline to a thermoplas�c matrix to achieve higher toughness). A baseline system is not prescribed in the Call because the baseline should be dependent on the proposed technology to isolate the effect of the proposed interlaminar enhancement.
Ques�on 02 Received 03 May 2024
Sec�on 2 "Research Opportunity Descrip�on" paragraph 3 - "The ACDC technical requirement is that the proposed technology solu�on will advance at least one Technical Objec�ve that is primarily or secondarily impacted by structures technology, listed below."
Please clarify how proposers will advance technical objec�ves without provided baseline metrics. As stated, it appears that offerors must have verifiable baseline data on current design and manufacturing prac�ces to meet solicita�on intent.
Government Response Ques�on 02, 08 May 2024
A baseline fiber/resin system is not given because it is dependent on the proposed technology (see Ques�on 1); therefore, the baseline metrics rela�ng to Technical Objec�ves must be proposed and proposals should substan�ate expected performance with and without the proposed interlaminar enhancement. Examples of poten�ally suitable metrics are provided in Atachment 1 ACDC SORE Task
3.2. Jus�fica�on may originate from public or private data; however, per Atachment 1 ACDC SORE, proposals should either include coupon tes�ng per Task 3, or a TRL Substan�a�on Report to provide that informa�on to the Government if such data has already been collected.
