The effects of the ceramic matrix composites on anti-wear and self-lubricating were investigated using a reciprocating test method and cylinder liner samples (boron copper cast iron) as the sliding partner.
The NASA Langley Research Center Curved Duct Test Rig (CDTR) is designed to test aircraft engine nacelle liner samples in an environment approximating that of the engine on a scale that approaches the full scale dimensions of the aft bypass duct.
A novel, integrally heated, rotational moulding tool has been developed to produce PEEK polymer liners, samples of which have then been overwrapped using CF/PEEK in a laser assisted tape-placement (LATP) process to produce demonstrator samples of a polymer lined COPV.
Our study includes three Beznoska samples: (i) Beznoska UHMWPE liner from 1991 – sample L3 in Tables 1 and 3, (ii) Beznoska UHMWPE liner from 1996 – sample L4 in Tables 1 and 3 and (iii) unused Beznoska UHMWPE liner from 2007 – sample PE3 in Table 2.
The sensitivity of the fissile mass measurement is enhanced by the use of two measurements, with and without a cadmium liner between the sample and a hydrogenous moderator that surrounds the sample.
A liner increment in sample crystallinity was observed with the cellulose amount as the sample was treated with 1% H2SO4, 0.25%, or 0.5% NaOH, corresponding to cellulose percentages of 51%, 66%, and 68%, respectively.
To perform abrasive wear test, pin-shaped sample of liner material has been developed for the purpose of testing.
Results showed that a hydraulic testing machine fitted with a pressure hydrogen chamber enables to create a liner collapse on small samples by explosive decompression experiments.
I bounce over to Silverlight Office/Chatter/Yammer and check what's up at the office, then catch up on New York Times, TechCrunch, Wall Street Journal, sample the interactive liner notes of the new David Sanborn record playing in the background, and keep an eye on news alerts before the White house press briefing direct feed lights up.
There are many one-liners you can find with a quick search on the internet, but here's a small sample of one-liners showing how you might use them: Never frown, you never know who might be noticing your smile.
