Deposition of carbon-based coatings on a continuously moving carbon fiber (CF) yarn is a new method for modifying the surface characteristics of the fibers. The coating is formed with the help of CO\*laser by way of a precipitating gaseous phase containing a mixture of carbon and hydrogen, and at th

β¦ Synopsis
temperature of 194K. On the other hand, when the sample temperature was raised to room temperature without evacuation, a considerable part of the absorbed C2H4 molecules was found to remain and to form a stable compound almost similar to that stated above.
We are now studying the structure and the properties of this compound in more detail

The relations between chemical vapor deposition (CVD) parameters and the resultant pyrolytic carbon microstructures have been examined for matrix deposition in fibrous carbon substrates. The parameters considered are temperature (1200-145O"C), pressure (20-630 Torr), C/H ratio (l/4-1/14), total flow
## Abstract **Summary:** Spinβdrawing yarn (SDY) and highβspeed spun (HSS) fibers were produced from recycled poly(ethylene terephthalate) pellets, and the oligomer deposition on the surface of fiber in supercritical carbon dioxide fluid was compared. The oligomer deposition was obvious for SDY, wh
## Abstract **Summary:** The effect of a surfaceβvacuumβevaporated ultrathin carbon layer on the bulk crystallization behavior of isotactic polypropylene (iPP) films was investigated by means of polarized optical microscopy, differential scanning calorimetry (DSC), and wideβangle Xβray diffraction.
