“…The Carbon fibers, produced from polyacrylonitrile and viscose fibers, petroleum pitch, etc., are now widely used for the reinforcement of plastics. High-strength carbon fibers have substantially lower surface energy: 53-57 mJ/m 2 estimated in [85], 29-49 mJ/m 2 according to data in [86]. Quite naturally the reduced s S values secure better compatibility between the carbon fibers and the polymers during the creation of composite materials reinforced with carbon fibers for various purposes.…”

Published data and the author's own data on the surface energy of hydrophilic oxides, silicates, and hydrophobic adsorbents based on them are reviewed. The prospects of using the combined Gibbs-Helmholtz-Young equation to obtain data on the surface pressure, heat of wetting, and wetting contact angle of hydrophilic and hydrophobic adsorbents are demonstrated. These data are used to estimate the thermodynamic characteristics of the surface and interfacial regions at the boundary between the materials and water. It is shown that the boundary layers of water close to the hydrophobic surfaces are more ordered while those close to the hydrophobic surfaces are less ordered than with liquid water.

“…Plasma surface treatment of fibers and use of the corresponding fibers in composites have been studied since the 1980s [15,91,92]. The plasma coating or polymerization seems to be one of the most effective methods to achieve both high strength and high toughness when suitable materials are selected for coating.…”

This review summarizes the recent (from year 2000) advancements in the interphase tailoring of fiber-reinforced polymer composites. The scientific and technological achievements are classified on the basis of the selected strategies distinguishing between i) interphase tailoring via sizing/coating on fibers, ii) creation of hierarchical fibers by nanostructures, iii) fiber surface modifications by polymer deposition and iv) potential effects of matrix modifications on the interphase formation. Special attention was paid to report on efforts dedicated to the creation on (multi)functional interphase in polymer composites. This review is round up by listing current trends in the characterization and modelling of the interphase. In the final outlook, future opportunities and challenges in the engineering of fiber/matrix interphase are summarized.

“…Precise contact angle measurement of fibrous materials is a difficult and complex process; however, several methods for measuring the wettability of fibrous material have been proposed (17)(18)(19)(20). In the early 1970s, Chwastiak (21) introduced a procedure for wicking rate measurement by enclosing a carbon fiber bundle in a glass tube so that the porosity is fixed for a given strand of carbon fibers.…”
