Statement of Objectives

Task Order 0002

High Temperature Composites Performance

1.0 Scope: The scope of this task order is to perform on-site research and development at the Air Force Research Laboratory, Materials & Manufacturing Directorate, Structural Materials Division (AFRL/RXC) located at Wright-Patterson Air Force Base in the area of behavior and life prediction of aerospace composite materials.

2.0 Objective: The objective of this task order is to conduct basic, applied, and advanced research to develop and validate multiscale and multi-physics models of polymer matrix composite, ceramic matrix composite, and other materials, in addition to developing novel composite characterization methods and conducting said tests. The developed models shall inform component, subsystem, and system level risk determinations that can be transitioned to AF and other DoD customers.

3.0 Description of Work: The contractor shall perform research and development related to the stated objective. Research activities may include, but are not limited to:

3.1 The contractor shall characterize composite materials and develop and improve computational tools to determine materials performance. Multi-scale and multi-physics characterization and other experimental results, computational tools, computer software, and models will be developed to determine potential applications of composite materials in DoD systems, predict lifetime and failure, and improve materials and processing designs. Verification and extensive validation of all models is required. Development of new mechanical testing methods to represent AF components and simulate real world failure modes shall be performed.

The material models shall be valid under service relevant temperature, environment, stress and time (TEST) conditions, including multi-axial and mission loading conditions and at critical component life-limiting locations such as holes and other similar sites with steep stress gradients.

Fabrication, characterization, and modeling shall be necessary to evaluate the influence of material composition, reinforcement designs, and processing method on component performance. Usage of data analytics and development of machine learning techniques to gain additional insight into material performance shall be performed.

3.2 Specific aerospace materials systems to be investigated include, but are not limited to ceramic, and organic matrix composites, filled elastomers, additively manufactured composites, functionally graded bonded materials, and high temperature composites. The investigations shall be conducted such that the understanding of the underlying physical, thermal, and chemical mechanisms is developed into a model useful for design and as manufactured performance prediction in the targeted materials within a relevant environment including moisture, fatigue loading, and thermoxidation.

3.3 Research related activities in the laboratory include fabrication of test samples, maintaining and modifying on-site laboratory equipment and computer software associated with research, and the acquisition of new Special Test Equipment (STE) or computer software to realize new capabilities.

3.4 The contractor shall perform incidental calibration and repair. Servo-hydraulic testing systems and laboratory equipment used for the research effort shall be maintained, scheduled for calibration, and repaired as necessary. The Base and Laboratory calibration and repair facilities (Precision Metrology Equipment Laboratory, PMEL) as well as the Equipment Maintenance Management Program shall be utilized to the greatest extent possible.

4.0 Program Management: Reviews will be an informal, ongoing activity due to the nature of the on-site research work. This can include reviews that will occur during the weekly Research Group (RG) meetings held between the government and contractor personnel. The contractor shall actively participate in both informal meetings and formal RG meetings. In addition, the contractor shall present the results of its R&D efforts at conferences and publish the results in appropriate peer-reviewed scientific journals.

5.2 Computer Software. It is anticipated that the successful contractor will be required to provide computer software, which includes, but is not limited to: subroutines used in commercial finite element codes, data reduction and visualization codes, deformation and life prediction models, and testing control codes.

5.3 Hardware. It is anticipated that the successful contractor will be required to provide hardware which includes, but is not limited to special test equipment (e.g., furnaces, test systems, displacement measurement systems, etc.).

5.4 Test Samples, Prototypes and Residual Materials. The contractor shall return to the Government all test samples, prototypes and residual materials not consumed in testing at the conclusion of the technical effort.

6.0 Operations Security (OPSEC) Requirements:

6.1 All contractors shall participate in all activities associated with the disciplines of the organization’s OPSEC program following appropriate measures required for this particular contract. This is required in an effort to reduce program vulnerability from successful adversary collection of possible sensitive unclassified and/or proprietary information, and violations of export control requirements. The prime contractor will ensure that all subcontractors, if applicable, conform to these requirements as required by the prime contractor. Guidance can be provided by AFRL/RX Security as needed.

6.2 Program Protection Plan (PPP): Any potential critical program information (CPI) generated as part of this effort will be reviewed to determine the need for a PPP, or to be included as part of an existing PPP.
