“…The most frequently used fibers are glass, carbon and aramid fibers, but the use of basalt, flax, hemp and thermoplastic fibers also increases significantly [1][2][3]. Beside the development of the fiber material many researchers have been working on optimising the cross section shape [4][5][6]. Kim and Park [7] compared concrete reinforced by C-shaped, solid and hollow carbon fiber.…”

Comparative analyses have been completed on hollow and solid E-type glass fibers. Single fiber tensile tests were performed and correlations have been determined between the geometry and the tensile strength of the fibers. The flexural properties of the solid and the hollow fibers have been determined with deflection tests. The hollow glass fibers showed higher tensile strength and flexural rigidity than the solid glass fibers in the case of similar outer diameter. The hollow fibers were filled with the help of capillary effect, and the filling process was examined as a function of the viscosity and the contact angle between glass and fluids. Relationship has been detected between fiber filling speed and the inner diameter of the fibers, and the filling speed was increased by the lower viscosity and contact angle.

“…Due to its high ductility, PCL offers attracting properties to PHB as it can reduce its low intrinsic fragility. PCL shows good miscibility behavior with a wide variety of polymers [21]; nevertheless, immiscibility with PHB has been reported in the literature together with different studies to increase compatibility between them [12,13,22,23].…”

2 AbstractThe present work is focused on the development of binary blends from poly(hydroxybutyrate) (PHB) and poly(caprolactone) (PCL). Miscibility, mechanical and thermal properties as well as blends morphology are evaluated in terms of the blend composition. Binary PHB-PCL blends were manufactured by melt compounding in a twin screw co-rotating extruder and injection molded. Composition of PHB-PCL covered the full range between individual polymers at 25 wt% increments. The obtained results show that PCL acts as an impact modifier thus leading to an increase in flexibility and ductility as the PCL content on PHB-PCL blends increases with a noticeable increase in elongation at break and on

“…The number of papers on the blending of biopolymers is vast, partly because of the huge number and wide diversity of these polymers and partly because of the increased interest in them. PLA and starch are the most often studied materials [36][37][38][39][40][41][42][43][44][45], but one could mention poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)/poly(vinyl phenol) [46], thermoplastic phenol formaldehyde resin/poly(!-caprolactone) (PCL) [47], poly(3-hydroxybutyrate) (PHB)/PCL [48], PLA/poly(butylene succinate) (PBS) [49,50], poly(3-hydroxybutyrate-co-3-hydroxihexanoate)/poly (lactic acid) (PLA) [51], PHB/PLA [52], etc. without even attempting to be comprehensive.…”

Abstract. Blends were prepared from poly(lactic acid) (PLA) and three thermoplastics, polystyrene (PS), polycarbonate (PC) and poly(methyl methacrylate) (PMMA). Rheological and mechanical properties, structure and component interactions were determined by various methods. The results showed that the structure and properties of the blends cover a relatively wide range. All three blends have heterogeneous structure, but the size of the dispersed particles differs by an order of magnitude indicating dissimilar interactions for the corresponding pairs. Properties change accordingly, the blend containing the smallest dispersed particles has the largest tensile strength, while PLA/PS blends with the coarsest structure have the smallest. The latter blends are also very brittle. Component interactions were estimated by four different methods, the determination of the size of the dispersed particles, the calculation of the Flory-Huggins interaction parameter from solvent absorption, from solubility parameters, and by the quantitative evaluation of the composition dependence of tensile strength. All approaches led to the same result indicating strong interaction for the PLA/PMMA pair and weak for PLA and PS. A general correlation was established between interactions and the mechanical properties of the blends.
