Introduction. Carbon–carbon (C/C) composites with their high strength and modulus at elevated temperatures, thermal stability and low weight are ideal materials for numerous structural applications.The matrices in C/C composites are usually derived either from phenolic, or polyfurfurylalcohol, resins and pitches.Polymeric resins have a principal Cited by: C.G.

Cash, in Encyclopedia of Materials: Science and Technology, Coal-tar Pitch Built-up Roofing. Coal-tar pitch membranes using coal-tar saturated organic felts is one of the oldest systems listed in Table systems perform very well historically, but are limited to very low slope applications and must be gravel surfaced because of the low viscosity of coal-tar pitch at.

Coal-tar pitch Petroleum pitch Synthetic pitch Matrix precursor Pitch vs. Resin Advantages ¾Higher carbon yield ¾Graphitizability ¾Development of open porosity on carbonization ¾Wide variety of structures and properties ¾Price Pitch vs.

Resin Advantages ¾Higher carbon yield ¾Graphitizability ¾Development of open porosity on carbonization. The matrix is a vitally important element in carbon – carbon composites.

It acts as a binder maintaining the alignment of the fi bers and fi ber bundles, also isolating the fi bers from one. Carbon Carbon Composites are those special composites in which both the reinforcing fibers and the matrix material are both pure carbon. Carbon-Carbon Composites are the woven mesh of Carbon-fibers.

Carbon-Carbon Composites are used for their high strength and modulus of rigidity. Carbon-Carbon Composites are light weight material which can.

Carbon/carbon composites have been made with coal tar pitch as matrix precursor and mesophase pitch based carbon fibers with different microstructures as reinforcements. Composites are made with. Carbon-Carbon Composites are composite materials consisting of a carbon. matrix reinforced by carbon fibers.

Infiltration of the preform with a liquid precursor: petroleum pitch/phenolic resin/coal tar. Pyrolysis/carbonization (chemical decomposition by heat. Flexure, compressive, and shear properties of the carbon matrix in carbon/carbon (C/C) composites made via a pitch impregnation method have been determined.

The pitch carbon matrix was made using the same densification cycle used in making the C/C composite. Cyclic compression tests were performed on the matrix by: 3. Fitzer E, Huttner W, Manocha LM () Influence of process parameters on the mechanical properties of carbon/carbon-composites with pitch as matrix precursor.

Carbon-carbon (CC) composites are categorized under the graphite/epoxy family of polymer matrix composites [2]. They consist of carbon fiber reinforced in a matrix graphite.

The element carbon is well recognized as having some anomalous properties, including its ability to embrace the three major divisions of materials science; polymers,Author: Weishen Yee. Coal tar pitch has been traditionally used in the aluminium and graphite industry as a binder for anode and electrode manu facture.

Further, coal-tar pitches have been studied as matrix precursors in carbon-carbon composites for carbon foam preparation and for energy storage carbons among others. Silicon carbide nanoparticles (nSiC) have been used to modify coal tar pitch (CTP) as a carbon binder.

The influence of ceramic nanoparticles on the structure and microstructure was studied. The structure of CTP-based carbon residue with various nSiC contents was analyzed by using SEM with EDAX, Raman spectroscopy, and X-ray diffraction. The effect of ceramic nanofiller Cited by: 5.

Coal-tar pitch, which is a by-product of the coke oven, is frequently used as a binder and impregnator in the manufacture of electrodes in the aluminium and steel industries. Coal-tar pitch can be also used as a matrix precursor for carbon/carbon composite due to high carbon by: 4. An oxidation process for stabilization of pitch-based matrices in the fabrication of carbon-carbon composites.

By oxidizing a fiber preform impregnated with petroleum-derived mesophase pitch at temperatures in the range of ° to ° C. for periods of the order of ten hours, the matrix is fixed in place within the preform so that softening, bloating, and expulsion.

Petroleum and coal tar pitches are excellent carbon matrix precursors or binders for manufacturing C/C composites; high density and coke yield can be obtained with these binders [10,11].The coke yield depends on the pyrolysis conditions and pitch : Jae-Yeon Yang, Jong-Hyun Park, Yun-Su Kuk, Byoung-Suhk Kim, Min-Kang Seo.

Sciences which are used to understand the properties and applications of carbons and graphites need to be described, comprehensively, in book format, at an up-to-date and introductory level. This book introduces the reader, comprehensively, to the sciences of structure of carbons, applications of carbon in nuclear energy, the chemistry of pitch carbonization, the spinnig of.

In addition to the high carbon yield and potential price advantage (owing to the relatively low cost of carbonaceous raw materials) of mesophase pitch, it has become a high-quality precursor material for fabricating high-performance and multifunctional carbon materials as shown in Figure 1, such as mesophase pitch-based coke, needle coke, high Author: Guanming Yuan, Zhengwei Cui.

What are Carbon-Carbon Composites?• Amorphous carbon matrix composite• Carbon matrix reinforced by graphitic carbon fibers• First developed inbut not intensively researched until the Space Shuttle Program 2.

What are C/C Composites. The U.S. Department of Energy's Office of Scientific and Technical Information. In Carbon Fiber Composites, the reader is introduced to a wide range of carbon fiber composites, including polymer-matrix, metal matrix, carbon-matrix, ceramic-matrix and hybrid composites. The subject is examined in a tutorial fashion, so that no prior knowledge of the field is required.The first high-performance carbon fibers on the market were made from rayon precursor.

PAN-based carbon fibers have long since replaced rayon in structural applications, but the latter’s “dogbone” cross-section and high-temperature performance often makes it the fiber of choice for carbon/carbon (C/C) composites in ablative heat shields.Short carbon fiber reinforced pitch-based carbon-carbon composites (SCFRCs) were fabricated under atmospheric environment using the mould pressing and semi-carbonization shaping technology.

The effect of the molding pressure and molding temperature on the density and the mechanical properties of the SCFRCs was studied in detail. Keywords: pitch.
