Thermoplastics reinforced by self-welded glass fibers: Effect of interfacial affinity on preferential segregation

In situ reactive interfacial compatibilization of polylactide/sisal fiber biocomposites via melt-blending with an epoxy-functionalized terpolymer elastomer

“…Fu et al found that the poly(ether)urethane had stronger interaction with carbon bers compared with PLA and it played a role of "solder" to weld the carbon bers into a more perfect network during their investigation of incorporating poly(ether)urethane into polylactide/carbon ber composites. 21 The similar phase morphology, so-called self-weld ber structure, 22,23 was obtained in this study for the PLA/SF/EGMA composites via in situ reaction processing. Part of the so EGMA phase enriched on the sisal ber surface, and welded the sisal bers to PLA matrix.…”

Effects of thermal histories on interfacial properties of carbon fiber/polyamide 6 composites: Thickness, modulus, adhesion and shear strength

“…10(b) and listed in Table 1. However, s ult does not give big differences to the s app as was reported that s ult values was much higher than s app [26,41,43]. It shows an average level for Water and 130 specimens and little increase for the others, which means a weak interface property and insignificant influence for residual stress on CF/PA 6 IFSS according to Pisanova et al [44].…”

“…Gorbatkina [40] pointed out that thermal stress also has a great effect on single fiber microcomposite IFSS test. He proposed ultimate adhesion strength, s ult , which is the shear stress required to produce shear failure locally in the interface and can be determined as follows [26,41]:…”

“…Micro-mechanical techniques such as fiber fragmentation [6,22,23], fiber pull-out [6,24,25] and micro-debonding [24,[26][27][28][29] have certain limitations to their use, and have not yet been standardized [30]. Alternatively, macromechanical testing methods can be used to indirectly assess fiber/ matrix interfacial adhesion, but they require the production of bulk composite laminates, which is time-consuming and costly.…”

Effect of Modified Sepiolite Nanofibers on Properties of cis‐Polybutadiene Rubber Composite Nanomaterials

“…The surface energy (SE), dispersive interaction (Disp. ), and polar interaction (Polar) were calculated using the contact angles of three kinds of liquid by Wu's equation: where is the liquid interfacial tension, and are the dispersive interaction and polar interaction of solid, respectively, and are the dispersive interaction and polar interaction of liquid, respectively, and is the contact angle which is measured before [27][28][29]. The rubber composites filled with sepiolite mineral nanofibers were prepared.…”
