“…This process requires a hot-press which would allow for temperature to be controlled within AE2 C [44] , which is manageable in a small-scale operation. In SPCs of PET nanofibrils produced by hot-compaction, it has been shown that only 10-20% of the fibrils were melted [46] , meaning that the composite obtained has a very high content of the reinforcement.…”

Nanofibrillar composites (NFCs) of polypropylene (PP) and poly(butylene terephthalate) (PBT) were produced with PBT as reinforcement. The two polymers were melt-blended, extruded and cold-drawn via necking in order to convert PBT into a nanofibrillar state. The drawn blend was used for manufacture of NFCs via compression moulding. PBT fibrils were isolated by selective dissolution of PP, and used to produce single polymer composites (SPCs), using a one-constituent approach (hot compaction), and a two-constituent approach (film stacking). NFCs and SPCs were subjected to tensile testing to obtain tensile modulus and tensile strength values. Scanning electron microscopy was used to observe PBT fibrils before and after processing of SPCs, having diameters between 100 and 150 nm. For the SPCs, the improvements in tensile modulus (compared to isotropic PBT) were 32% and 36% for the one constituent and two constituent approach, respectively. The corresponding values for tensile strength were 20% and À18%. NFCs of PP/ PBT showed an improvement of 55% in tensile modulus, and 50.24% in tensile strength as compared to isotropic PP.

“…Ward and coworkers [7][8][9][10][11] further developed this type of composite material using the 'hot compaction' technique. Following this study, opening literatures has reported numerous studies on the preparation of self-reinforced polypropylene (PP) [8,[11][12][13][14][15][16][17], polyethylene terephthalate (PET) [4,9,[18][19], polymethyl methacrylate [20], liquid crystal copolymer [21][22], polylactic acid [23], and poly amide [24][25][26] composites. In particular, the self-reinforced PP composites are now available on the market under the trade name Curv ® , Armordon ® , and Pure ® [5].…”

“…These polymers can be entirely melted down at the end of their product life for recycling. The self-reinforced polymeric composite material possesses many advantages and features, such as thermoformability, high stiffness, high tensile strength, outstanding impact resistance at low density, and containing no glass [2][3][4][5]. Because the reinforcement and the matrix are compatible chemically; therefore, they usually have no interfacial problems.…”

Abstract. Self-reinforced poly(ethylene terephthalate) (PET) composites prepared by using a modified film-stacking technique were examined in this study. The starting materials included a high tenacity PET yarn (reinforcement) and a low melting temperature biodegradable polyester resin (matrix), both of which differ in their melting temperatures with a value of 56°C. This experiment produced composite sheets at three consolidation temperatures (T c : 215, 225, and 235°C) at a constant holding time (t h : 6.5 min), and three holding times (3, 6.5 and 10 min) at a constant consolidation temperature of 225°C. This study observed a significant improvement in the mechanical properties obtained in self-reinforced PET composites compared to the pure polyester resin. The results of tensile, flexural, and Izod impact tests proved that optimal conditions are low consolidation temperature and short holding time. The absorbed impact energy of the best self-reinforced PET composite material was 854.0 J/m, which is 63 times that of pure polyester resin.

“…They are currently utilized for manufacturing automotive components, luggage, sporting, and protective goods, and their flame retardation properties attracted significant interest [5]. However, the thermal stability and related service temperatures of srPP composites are relatively low; therefore, various attempts have been made to develop srPC-based materials from high temperature polymers [4] such as polyethylene terephthalate (PET) [6][7][8] (for example, PET-based soft drink bottles can be easily converted to textile fibers using a simple recycling procedure [9]). Many currently manufactured textile products already contain recycled PET (rPET) fibers, and their use for the development of novel srPC composites fits the described 'upcycling' strategy relatively well.…”

Abstract. Creep deformation of polymers results from their inherent viscoelastic nature that changes polymer's shape with time. Creep response represents an important property of thermoplastic composites that affects their dimensional stability, especially in applications requiring the material ability to support relatively high loads for long periods. This work examines the creep behavior of self-reinforced recycled poly(ethylene terephthalate) (srrPET) composites, which were produced by film stacking from fabrics composed of double covered uncommingled yarns with recycled PET homopolymer filaments (serving as the reinforcements) and copolymerized PET (mPET) filaments (serving as the matrix). The short-term creep behavior of both srrPET and mPET was studied in the single cantilever mode below and above the glass transition temperature, and the obtained data were analyzed using the Findley's viscoelastic and Burgers four-element models. The long-term creep behavior of srrPET specimens with and without open circular holes was described using an Arrhenius-type time-temperature superposition principle.
