Sole Source Justification_COSigned_Redacted.pdf

This document is a Single Source Justification (Simplified Acquisition) for acquiring composite tooling prepreg from Toray Advanced Composites for a High Gain Collapsible Tube Mast Antenna project by the Air Force. The specific procurement involves purchasing 550 sq ft of Toray AmberToll HX42 12K 2x2 twill prepreg and 100 sq ft of Toray AmberTool HX42 3K 2x2 twill prepreg to improve tooling for processing high gain antenna composite tube masts. The justification emphasizes that Toray Advanced Composites is the only known vendor capable of producing composite tooling prepreg meeting the project's stringent requirements, including ability to cure at low temperatures (<180degF) to a rigid self-supporting state and create a repeatable surface finish for aerospace applications.

The document, dated April 2021 and marked as Controlled Unclassified Information, details that the current request is for composite tooling prepreg sufficient to produce three ~10-foot long tools using existing metallic tooling. The Contracting Activity is 377 MSG/PKB, with the estimated contract cost redacted. Section D notes that while other composite tooling prepreg vendors exist, none meet the technical and schedule requirements for this specific High Gain CTM Antenna project. The Contracting Officer has determined, in accordance with FAR guidelines, that only a single source is reasonably available, with the determination signed and dated for 30-Jun-2025.
