E-MAIL: Andrea Bone, andrea.bone@msfc.nasa.gov. NASA/MSFC plans to issue a Request for Quotation (RFQ) for Ceramic Matrix Composite Tensile Specimens. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/MSFC intends to purchase the items from Honeywell Advanced Composites. 1. T300/SIC Melt infiltrated Tensile samples per NASA Drawing(s). Volume fraction of fibers is to be between 38 and 45% with 1K Tow Size. Samples need to be approximately 0.120 inches thick per NASA Drawing(s). All specimens are to be delivered within 12 weeks. The fiber architecture is to be plain weave, 0/90 layup. Provide images of demonstrated 10% or less residual, free silicon in the matrix. Density should be at least 2.0 G/CC. This melt infiltration processed T300/SIC must have published or submitted for publication, room temperature values of: Average tensile strength of 50 KSI or greater, and an interlaminar shear strength of 3.5 KSI or greater: quantity 54 1-ea; 2. Enhanced T300/SIC chemical vapor processed tensile specimens. The enhancement is to provide additional oxidation resistance. Fiber volume fraction is between 38% & 45%, with 1K TOW. Specimens are to be per NASA Drawing(s). All specimens are to be delivered within 12 weeks. The fiber architecture is to be plain weave, 0/90 lay-up. Thickness 0.120 inches per drawing(s). This CVI enhanced C/SIC must have published, room temperature values of: Average tensile strength of 35KSI or greater, and an average tensile strain at maximum stress of 0.5% or greater, and a nonlinear stress-strain curve: quantity 18 1-each; 3. Hi-Nicalon/SIC melt infiltrated tensile samples per NASA Drawing(s). Volume fraction of fibers is to be between 38% and 45%. Samples need to be approximately 0.120 inches thick per NASA Drawing(s). All specimens are to be delivered within 12 weeks. The fiber architecture is to be plain weave, 0/90 lay-up. Density is to be at least 2.4 G/CC. This melt infiltration processed Hi-Nicalon/SIC must have room tempearture property values of: Average tensile strength of 45 KSI or greater: quantity 16 1-each; 4. T300/SIC Chemical vapor infiltration processed tensile samples per NASA Drawings. Volume fraction of fibers is to be between 38 & 45% with 1K tow. Samples need to be approximately 0.120 inches thick per NASA Drawing(s). All specimens are to be delivered within 12 weeks. The fiber architecture is to be plain weave, 0/90 lay-up. Density is to be greater than 1.95G/CC. Demonstrated 10% or less residual free silicon in the SIC Matrix. This CVI processed C/SIC must have published room temperature property values of: Average tensile strength of 60KSI or greater, average tensile strain at maximum stress of 0.8% or greater, and a nonlinear stress-strain curve: quantity 18 1-each; The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on August 29, 2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
