“…Specially, the development of interfacial crystallization occurring in the interface between fiber and matrix would enhance interfacial adhesion [14][15][16][17][18][19][20]. It is generally accepted that the interfacial crystallization would substantially influence mechanical behavior [21][22][23][24].…”

Abstract:In this work, an economical modifier silane agent-KH550-was used for surface treatment of basalt fiber. Then, a biodegradable poly(butylene succinate) (PBS)/modified basalt fiber (MBF) biocomposite was successfully developed. The effects of silane treatment and fiber mass content on crystalline structure, isothermal crystallization process and mechanical performance of composites were evaluated. The interfacial crystallization of PBS on the surface of MBF was investigated by using a polarized optical microscope (POM). The transcrystalline (TC) structure could be clearly observed and it grew perpendicular to the surface of MBF, which boosted the nucleation ability on PBS crystallization and the strong interfacial interaction between PBS and silane-treated basalt fiber. Under isothermal crystallization kinetics, the incorporation of basalt fiber enhanced the crystallization rate and reduced the crystallization half-time values of composites compared with that of neat PBS due to a heterogeneous nucleation effect. Furthermore, tensile results confirmed that the presence of MBF could greatly improve the tensile strength and modulus. The predicted interfacial shear strength (IFSS) suggested that an enhancement of interfacial bonding could be realized via interfacial crystallization, which was also verified by SEM images. The PBS/MBF biocomposites can be applied in many fields as a low-cost, lightweight, and biodegradable composite material.

“…The concept was first described by Capiati and Porter [2] decades ago for high density polyethylene. Following their pioneering work, single polymer composites have been successfully manufactured for a variety of different semi-crystalline and amorphous polymers, including polyethylene [3], polypropylene [4], poly(ethylene napthalate) [5], poly(lactic acid) [6], polyamide [7] and poly(methyl methacrylate) (PMMA) [8][9]. Several techniques have been reported for the production of these composites, such as film-stacking [10] which will be used in this study, hot compaction [11] and co-extrusion [12].…”

Abstract. The dynamic mechanical properties of single polymer composites of poly(methyl methacrylate) (PMMA) reinforced with electrospun PMMA nanofibers of different diameters are reported. The effect of electrospinning parameters on the morphology and diameters of the electrospun high molecular weight PMMA was investigated in order to obtain suitable diameters for the reinforcing fibers. Scanning electron microscopy (SEM) was used to study the morphology and diameters of the nanofibers produced at different electrospinning conditions. It was found that polymer solution concentration influences the diameter of the electrospun nanofibers more than the spinning voltage and spinning distance. SEM analysis of the PMMA nanofibers showed that the fibers had a smooth, regular and cylindrical morphology with no beads and junctions. Effects of the processing temperature for the preparation of the single polymer composites via film stacking were investigated. Dynamic mechanical analysis showed a pronounced improvement in the storage modulus of the composites compared to the matrix.

The original concept of self-reinforced composite, a composite with matrix and reinforcement from the same polymer, was presented by Capiati and Porter [1] three decades ago for high density polyethylene. Later this concept was adopted to polypropylene (PP) [2][3][4][5] [20,21]. Particularly, in a series of recent papers, Alcock and coworkers [22][23][24] described composite materials in which both the reinforcement and the matrix were based on PP. The related composites under the trade name of PURE ® are produced from highly oriented co-extruded tapes having a skin-core-skin (A:B:A) morphology. The skin layer (A) contains a PP random copolymer, whereas the core layer (B) is composed of PP homopolymer.Since the copolymer skin layer has a melting temperature below that of the homopolymer core, selfreinforced (also termed as homocomposites or all-PP composites) PP systems can be produced using a suitable processing window. Note that during consolidation the PP copolymer forms the matrix, while the highly oriented PP homopolymer fraction acts as continuous reinforcement. This approach (i. e. copolymer for the matrix and homopolymer for the reinforcement) can be used to produce all-PP composites using the film stacking technique, as well [25]. The most recent development with all-PP composites is to exploit the polymorphism-related difference in the melting range between the beta-(giving the matrix) and alpha-phases (serving as reinforcement) PPs [26,27]. All-PP composites are characterized by their outstanding mechanical properties at very low density. Their main advantage over conventional glass fiber reinforced ver-519 * Corresponding author, e-mail: karger@ivw.uni-kl.de © BME-PT and GTE Abstract. All polypropylene (all-PP) composite laminates with unidirectional (UD) and cross-ply (CP) lay-ups were produced by hot consolidation from oriented coextruded PP tapes (PURE ® ). The consolidation of the tapes, wound on a steel plate, occurred in autoclave vacuum bag molding. The set processing conditions resulted in all-PP laminates of high rigidity as the PP copolymer surface layers of the tapes were molten and thus forming the matrix, while their PP homopolymer core remained unaffected and thus fulfilled its role as reinforcement. Specimens cut off from the laminates were subjected to dynamic mechanical thermal analysis (DMTA) in a broad temperature range (T = -50…120°C) at various frequencies (f = 10 -2 …10 1 ). For the DMTA results the time-temperature superposition principle was adopted and master curves in the form of storage modulus vs. frequency (f = 10 -9 …10 20 ) and loss factor vs. frequency were created.
