The universal structural role of collagen fiber networks has motivated the development of collagen gels, films, coatings, injectables, and other formulations. However, reported synthetic collagen fiber fabrication schemes have either culminated in short, discontinuous fiber segments at unsuitably low production rates, or have incompletely replicated the internal fibrillar structure that dictate...

Ductile fiber-reinforced cement-based composites (DFRCCs) are being investigated for new design as well as retrofitting of structures in seismic regions. DFRCC is highly ductile and is characterized by strain-hardening in tension to strains over 3% and by unique cyclic loading behavior. To accurately predict the structural performance of DFRCC components under cyclic and seismic loading, a robu...

Consolidated-drained triaxial compression tests were conducted to compare the stress-strain and volume change response of sands and clayey sands reinforced with discrete randomly distributed poly-propylene fibers. The influence of various test parameters such as fiber content (0.0%, 0.5% and 1.0% by weight), clay content (0%, 10% and 20% by weight), relative density (50% and 90%) and confining ...

ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(pan)-based carbon fiber. the surface characteristics of carbon fibers were characterized by x-ray photoelectron spectroscopy (xps). the interfacial properties of carbon fiber reinforced polyamide 6 (cf/pa6) composites were investigated by means of the single fiber pull-out tests. as a result, it...
