“…Moreover, their interfaces between the composite components are potentially improved due to the chemically identical/ compatible, which can result in the superior mechanical properties of the single-component composites [1,9]. Resently, semi-crystalline thermoplastics polymers such as polyethylene [10][11][12][13], polyester [14][15][16], isotactic polypropylene [17,18], etc. are used to prepare the single-component composites via specific processing, and they all presents excellent properties.…”

A novel single-component composite based on phthalonitrile end-capped polyarylene ether nitrile (PEN-Ph) was prepared successfully via hot compression. In the PENPh system, the crosslinking reactions and crystallization exist simultaneously, and the crystals are embedded in the crosslinked PEN-Ph matrix, which can work as reinforcement. Analysis of the Non-isothermal cold crystallization kinetics of the PEN-Ph system was performed by using differential scanning calorimetry (DSC), and the activation energy of the crystallization process is obtained to be 217.5 kJ·mol −1 . The DSC and SEM analysis provide the evidence for that there exists crosslinking reactions as well as crystallization behavior. However, the crosslinking reaction with excessive speed will restrict the crystallization behavior of the PEN-Ph. Furthermore, the DMA and mechanical measurements indicate that the glass transition temperature and mechanical properties are influenced by not only the crosslinking degree but also the crystallinity. The tensile strength of the single-component composite is 111.0 MPa, increased by about 10 MPa than that of amorphous PEN-Ph sheet.

“…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.

“…This type of composite with only one constituent was first investigated by Capiati and Porter [5]. Different production processes for self-reinforced composites were developed, such as hot compaction [6,7], film stacking [8] and bicomponent tape technology [9,10]. In the hot compaction technology, pressure and heat are applied to stacks of polymeric tapes.…”
