TL;DR: In this paper, the surface structure and chemistry of various surface oxidized HT carbon fibers, an IM and a HM carbon fiber were studied by SEM, STM, CAM (contact angle measurement), XPS and TPD with special reference to adsorbed oxidized water.

TL;DR: The surface functional groups of various surface oxidized carbon fibers were chemically modified by reaction with methanol/HCl and reduction with sodium boron hydride and lithium aluminum hydrate as discussed by the authors.

TL;DR: In order to gain a better understanding of the role that the carbon fiber surface plays in adhesion, it is necessary to be able to observe it at atomic dimensions as discussed by the authors, and two scanning probe microscopes have been found to be particularly useful for this task.

TL;DR: In this paper, the results of XPS (O1s:C1s ratio) can be correlated with the results from TPD, however, the work of adhesion results as determined by CAM (contact angle measurements) do not correlate with either of the other two methods.

TL;DR: In this article, unidirectional composites were fabricated with fibers of different modulus (HT, IM, HM) and different surface treatments using various thermoplastics as the matrix Mechanical properties were determined and correlated with the properties of the fibers.
