Studies on “Mesophase”-Pitch-Based Carbon Fibers

" 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...

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...

Computational Modeling of Ring Textures in Mesophase Carbon Fibers

Carbon fibers are widely used in many industrial applications due the fact of their excellent properties. Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the melt spinning process, which is a flow cascade consisting of pressure driven flow-converging die flow-free surface extensional spinline flow that modifies the pr...

High Thermal Conductivity Mesophase Pitch-Derived Graphitic Foams

1. Introduction In recent years there has been an increasing number of applications requiring more efficient and lightweight thermal management such as high-density electronics, hybrid diesel-electric vehicles, communication satellites, and advanced aircraft. The primary concerns in these thermal management applications are high thermal conductivity, low weight, low coefficient of thermal expan...
