Shortening Stabilization Time Using Pressurized Air Flow in Manufacturing Mesophase Pitch-Based Carbon Fiber

Meltblown Solvated Mesophase Pitch-Based Carbon Fibers: Fiber Evolution and Characteristics

Potentially low-cost continuous carbon fibers are produced from solvated mesophase pitch through a patented meltblowing process. The structural evolution and properties of the fibers are characterized by various analytical methods. The meltblown fibers are continuous fibers which are collected into a fibrous web form, and the diameter of the filaments is attenuated by the flow rate of air strea...

Mesophase Pitch-based Carbon Fiber and Its Composites: Preparation and Characterization

Simulation of Flow–induced Texture Formation in Mesophase Pitch

Mesophase pitches are multicomponent discotic nematic liquid crystals (DNLCs), whose characteristic molecular weight is intermediate between low molar mass and polymeric nematic liquid crystals. The distinguishing features of the mechanical behavior can be summarized by stating that LC materials exhibit anisotropic, non-linear, viscoelastic behaviour quite distinct from Newtonian viscous materi...

" Mesophase " - Pitch - Based Carbon Fibers : Part ‡ U Mechanical Properties and Thermal Expansion

Mechanical properties such as strength, modulus and strain to break, and coefficients of thermal expansion of mesophase-pitch-based carbon fibers were measured using the fibers with four different microtextures heat-treated at two different temperatures. The textures were radial with wedge, radial, random and onion. In strain to break of the fibers, there were not so much difference with differ...

Production of graphene oxide from pitch-based carbon fiber

Pitch-based graphene oxide (p-GO) whose compositional/structural features are comparable to those of graphene oxide (GO) was firstly produced by chemical exfoliation of pitch-based carbon fiber rather than natural graphite. Incorporation of p-GO as nanofillers into poly(methyl methacrylate) (PMMA) as a matrix polymer resulted in excellent mechanical reinforcement. p-GO/PMMA nanocomposite (1 wt....
