In this work, ozone modification method and air-oxidation are used for the surface treatment of polyacrylonitrile(PAN)based carbon fiber. The surface characteristics of carbon fibers are characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites are investigated by means of the single fiber pull-out tests. As a ...

The use of fabrics in the form grids embedded cementitious matrices—usually termed as textile-reinforced mortar, fiber-reinforced matrix, or concrete—demonstrate a more stable performance elevated temperature conditions compared with polymers. This study investigated residual tensile properties bare yarns and mortar after exposure to 100 °C, 200 300 °C. Three different coated fabric textiles we...

The use of carbon nanostructures to create electrically conductive networks in continuous fiber reinforced composites has been explored through the modification of the fibers. This alternative tries to avoid problems presented in most studied approach which consists of nanostructures addition in the matrix. Two alternative methods to CVD have been studied: electrophoretical deposition and nanor...

In this work, new magnetic amphiphilic composites were prepared by chemical vapor deposition with ethanol on the surface of hydrophilic natural chrysotile matrix containing Fe catalyst. XRD, Raman, Mössbauer and SEM analyses suggest the formation of a complex nanostructured material composed of hydrophobic carbon nanotubes/nanofibers grown on the hydrophilic surface of the MgSi fiber mineral an...

Despite the excellent osseointegration of carbon-fiber-reinforced polyetheretherketone (CFR/PEEK) with a surface hydroxyapatite (HA) coating, the bone-implant interfacial shear strength of HA-coated CFR/PEEK after osseointegration is unclear. We examined the interfacial shear strength of HA-coated CFR/PEEK implants after in vivo implantation in a rabbit femur-implant pull-out test model. HA coa...

Conductive polymers are interesting materials for a number of biological and medical applications requiring electrical stimulation of cells or tissues. Highly conductive polymers (polypyrrole and polyaniline)/Antheraea mylitta silk fibroin coated fibers are fabricated successfully by in situ polymerization without any modification of the native silk fibroin. Coated fibers characterized by scann...

An experimental study of the consolidation and associated grain growth kinetics of silicon carbide monofilaments sputter coated with nanocrystalline Ti-6A14V has been conducted. Bundles of coated fibers were consolidated using a hot isostatic press (HIP) equipped with an eddy current sensor for in situ measurement of the specimens’ relative density. The experiments were conducted at temperature...
