In addition to blending with additives, glass and carbon fiber reinforcements are used to enhance the stiffhess and the strength of polystyrenes. Thetmofil and RTF supply commercial glass fiber filled polystyrenes. RTF also sirpplies carbon fiber filled polystyrenes. 

Glass and carbon fiber reinforcements are the most important filler for all of the PEK family. While elastic extensibility is sacrificed, the additional heat resistance and moduli improvements allow glass- or carbon-fiber formulations entry into many applications. 

Glass and carbon fiber reinforcements are the most important fillers for all of the PEK family. While elastic extensibility is sacrificed, the additional heat resistance and moduli improvements allow glass or carbon fiber formulations entry into many applications. PEK is polymerized either through self-condensation of the structure in Fig. 1.32a, or via the reaction of intermediates as in Fig. 1.326. Since these polymers can crystallize and tend, therefore, to precipitate from the reactant mixture, they must be reacted in high boiling solvents close to the 320°C melt temperature. ... 

The polymer has very high tensile strength, an Underwriter s Laboratories (UL) temperature index of 170°C, flame resistance, and low smoke emission. The polymer is resistant to alcohols, acids, and hydrocarbon solvent but will dissolve in partially halogenated solvents. Both glass- and carbon fiber-reinforced grades are available.

Taking into account (i) that the width of the transcrystalline layers in this particular case is much smaller than that of the well studied transcrystalline layers in glass and carbon fibers reinforced PP and other polymer matrix composites [93-96], and (ii) the superior mechanical properties profile of the samples of MFCs from LDPE/PET blend [49], at least in this particular case one can assume a positive effect of the transcrystalline layers regarding the mechanical properties profile.

Another interesting approach for considerable improvement of the interfacial adhesion is offered by the phenomenon of transcrystallization. The formation of transcrystaUine layers comprising PP spheroUtes on the surface of glass and carbon fibers reinforced PP and other polymer matrix composites is well known and widely studied case (e.g., [28]). Lamellar transcrystalline layers of PP or of PE (matrix) have been observed also on the surface of PET microfibrils (reinforcement) in the respective microfibrillar composites (MECs) prepared from the PP/PET or PE/PET blend [29-32]. 

This method, resembling to conventional composite manufacturing techniques, uses melt or powder impregnations. The reinforcing fibers are impregnated with a highly viscous polymer resin (similar to the production of glass and carbon fiber-reinforced...
