Surface induced crystallization in ultrahigh-modulus polyethylene fiber-reinforced polyethylene composites

Multi-Scale Carbon (Micro/Nano) Fiber Reinforcement of Polyetheretherketone Using High Shear Melt-Processing

“…Along the length of the fiber, evidence of transcrystallinity, or surface crystallization of PEEK, is evident by the directional crystal growth from the carbon fiber, resulting in a preferred orientation (indicated in the enclosed region in Figure 3d). Surface crystallization is a well-studied occurrence in CF-PEEK composites with the highlighted region matching known transcrystallinity features [22]. In general, polymer surface cyrstallization on CF provides good adhesion between the high stiffness fiber and less stiff polymer, resulting in enhanced mechanical properties [23].…”

Controlled Interphases in Glass Fiber and Particulate Reinforced Polymers: Structure of Silane Coupling Agents in Solutions and on Substrates

“…For these reasons, few of the papers dealing with transciystals reported AO values. Recently, the induction time approach has been proposed as a new method to study transcrystallization (34,35). When an isothermal heterogeneous crystal growth takes place, a threshold period exists when the formation and remelting of the precursors of nuclei takes place.…”

Transcrystallization of PTFE fiber/PP composites?III. Effect of fiber pulling on the crystallization kinetics

“…1,2 Several rated in semicrystalline polymers, under approsuggestions have been proposed to account for the priate conditions, a highly oriented layer is develformation of TCL. [3][4][5] The most interesting subject oped at the fiber/matrix interface. This distinct is the flow-induced (stress-induced or strain-inmorphology is called transcrystalline layer (TCL), duced) crystallization to result in the morphology and is the consequence of a high nucleating ability of TCL.…”

“…Results showed that shear flow has a pronounced effect on the reduction of induction time, shearing to the onset of crystallization. 11,12 fiber (the diameter of the fiber is 30 mm, and the dimenBuerger et al 13 found that there is an inverse sions of the mold are 10 1 6 1 1 mm 3 ).…”

“…A small rectangular mold, 10 1 6 1 1 mm 3 , 142ЊC, to obtain accurate measurement of TCL made of silicone rubber was used to contain the thickness. PP powder, as shown in melt is due to the presence of entanglements, which causes the elastic extension of the chain segments between them.…”
