A -- COMPOSITE MATERIALS TESTING SOL RFO3-154476 DUE 091000 POC Glen M. Williams, Contracting Officer, Phone (216) 433-2885, Fax (216) 433-2480, Email Glen.M.Williams@grc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=22#RFO3-154476. E-MAIL: Glen M. Williams, Glen.M.Williams@grc.nasa.gov. NASA/GRC plans to issue a Request for Offer (RFO) for both mechanical and physical testing of 8 different carbon/carbon (C/C) and 8 different carbon/silicon carbide (C/SiC) ceramic matrix composites (CMCs) in support of the Pratt&Whitney/NASA GTX program. Mechanical testing will consist of 4pt flexural strength testing (1"x6"x0.1" specimen, 70F to 3200F, inert atmosphere), and interlaminar shear strength testing by both the double-notch shear method (0.5"x1.25"x0.1" specimen, 70F to 3200F, inert atmosphere) and the short-beam shear method (TBD specimen, 70F to 3200F, inert atmosphere). Physical properties will consist of cross-ply and in-plane thermal conductivity testing by both the comparative rod method (1" diax1" specimen, 70F to 1800F, inert atmosphere) and the radial inflow method (.7"x.7"x2" specimen, 1800F to 3500F, inert atmosphere), and permeability testing (2.055" and 2.315" ID tubes, 70F to 1300F). An option to perform additional flexural and thermal conductivity tests is also included.The total period of performance is 6 months. NASA/GRC intends to purchase the items from Southern Research, Birmingham, AL 35255 using 10 U.S.C. 2304(c)(1) Only one responsible source and no other supplies or services will satisfy agency requirements. Southern Research is the only source capable of performing inert atmosphere testing to 3200F, radial inflow thermal conductivity testing to 3500F and permeability testing room temperature to 3200 degree F in an inert atmosphere using the radial in-flow thermal conductivity test. Results of these tests using Southern Research equipment will be compared to previous tests of C/C and C/SiC CMCs performed by the same contractor using the same equipment. This ensures a scientifically acceptable comparison of the results. The Government intends to acquire a commercial item using FAR Part 12. 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 11, 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. An Ombudsman has been appointed. See NASA Specific Note "B". Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nasanote.html Posted 07/24/00 (D-SN478169). (0206)
