E-MAIL: Kimberly D. Duncan, k.d.duncan@larc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR 1-168-RCE.1095 Fabricate Graphite-Epoxy Composite Test Specimens. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to notify the posting of a REVISED DROP OFF PANEL 2 DRAWING. The specifications listed in the combined synopsis/RFQ are hereby deleted and replaced with "The Metals & Thermal Structures Branch (MTSB) of NASA LaRC requires the fabrication of research quality test specimens for the "Cryogenic Tank Subcomponent Test and Development" Program. The panels will be used for coupon pull/peel-off tests and for a large integrated panel test at the Cryogenic Pressure Box Test (CPB) Facility. The specimen shall be a fabricated using Graphite-Epoxy IM7/977-2 (Gr-Ep) tape and fabric. The specimens shall be hand laid-up, co-bonded using FM300 film adhesive and cured in an autoclave for adequate consolidation. The Contractor shall purchase all materials (IM7/977 Gr-Ep and FM300 Adhesive, 6-8 week delivery). The Contractor shall fabricate all required tooling and shall follow the design drawings developed by LaRC. A full set of complete design drawing will be provided to the awarded Contractor. Only design sketches are available at the present time. The CPB panel shall be approximately 65 in. by 76 in. and shall have external I-stiffeners. All of the test panels will be subjected to combined thermal and mechanical loading at LaRC. The stringers shall be co-bonded to a flat Gr-Ep panel for the coupon pull/peel off specimens and a curved Gr-Ep panel for the CPB panel using FM 300 film adhesive Tolerances shall be +/- 0.005 in.. The panels are: A. (24 each) Coupons for pull/peel-off tests with a design similar to the curved Gr-Ep panel (see attached peel/pull off specimen drawing), B. (1 each) plan form 65 in. by 76 in. curved 156 in. radius Gr-Ep cryogenic pressure box panel. Deliverables: 1) The Contractor shall deliver biweekly reports on progress of work completed. 2) The Contractor shall participate in bi-weekly teleconferences with the NASA Technical Monitor. 3) The Contractor shall deliver the panels by 7/21/00 and the curved panel by 8/25/00. No extension will be granted. The contractor must meet the specified days. 4) The Contractor shall record the weight of each component (Stringers and curved membrane) of the curved Gr-Ep panel before assembly. 6) The Contractor shall NDE all panels (NDE with a C-Scan for inclusions, voids, and gaps), number, and measure for quality assurance before delivery. 7) The Contractor shall provide a summary report at the end of the contract on the fabrication process used to fabricate the panels. The summary shall be in the form of a contractor report. NOTE: A REVISED DROP OFF PANEL 2 IS ATTACHED. The following design drawings are available on the Internet at: http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=23 a) Cryogenic pressure box panel pull/peel-off coupon design, (b) Cryogenic pressure box panel design." The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on May 19, 2000.
