Aminimide-cured epoxy resins as surface modifiers for mica flakes in particle-reinforced thermoplastics

Effect of pimelic acid treatment on the crystallization, morphology, and mechanical properties of isotactic polypropylene/mica composites

“…It had been found that MC flakes orientate in the direction of melt flow during injection molding [5, 7, 11, 24, 26–28] and increase the tensile and flexural strength [5, 24]. Inubushi et al [13] indicated that the interface is the most highly stressed region in a composite material. It must be effective to lower these stress concentrations either by placing a buffer material of intermediate modulus or a ductile one in the interphase.…”

“…Therefore, MC‐reinforced PP composites possess several excellent properties, among them are improved strength, high stiffness, good dimensional stability, enhanced heat resistance and electrical resistivity, and reduced cost [1–3]. In the literature, the mechanical properties [4–22], fracture mechanisms [23–28], dynamic mechanical behaviors [29–31], rheological behaviors [4, 21, 32–35], crystallization behaviors [14, 30, 31, 36–39], surface texture [40], mechanical degradation of MC during processing [41], ultrasonic weld strength [42], heat transmission behavior [43], coupling mechanisms of chlorinated paraffins [44, 45] in PP/MC composites, and the mechanical properties of PP/poly(vinyl butyral)/MC [46], PP/ethylene vinylalcohol copolymer/MC [47], and PP–MC–glass mat‐reinforced thermoplastics composites [48] were reported.…”

Prediction of mechanical properties of composites of HDPE/HA/EAA

“…The results of E, σ B and ε B shown in Table 1 suggest that several parameters affect the mechanical properties of the composites: average particle size and particle size distribution of the filler (Busigin et al, 1983), adhesion of the compatibilizer or coupling agent to the filler (Newman and Meyer, 1980), the wettability of the filler (Inubushi et al, 1988) and the amount of compatibilizer or coupling agent used (Anderson and Farris, 1988). It is also important to note that for small particles, the interface between the filler and the binder plays a significant role (Inubushi et al, 1988;De Debnath and Khastgir, 1987;Jarvela and Jarvela, 1996).…”

“…It is also important to note that for small particles, the interface between the filler and the binder plays a significant role (Inubushi et al, 1988;De Debnath and Khastgir, 1987;Jarvela and Jarvela, 1996). The experimental Young's modulus values were compared with the theoretical predictions given by the Verbeek model (Verbeek, 2001(Verbeek, , 2003, and by the Guth (Guth, 1945) and Kerner modified models (Kerner, 1956).…”

Epoxy resins as surface treatments for mica flakes in propylene/ethylene copolymer composites

“…A new surface treatment based on an epoxy resin was used because of its low price compared to a silane coating. A previous study [ 13] using a combination of an epoxy prepolymer and various aminimide curing agents had already been carried out. The results give evidence for (i) the same increase in tensile strength with these epoxy systems comp釭ed to unfilled matrix as when silane coupling treatments are used, and for ( ii) the importance of the choice of the curing agent used to harden the epoxy resin.…”
