Special Issue Information

Dear Colleagues,

Following the success of the Special Issue of Polymers, “Advanced Thermoplastic Polymers and Composites”, we are delighted to reopen this Special Issue, now entitled “Advanced Thermoplastic Polymers and Composites II”.

In the last decade, the design and material innovation for manufacturing composites have reached new heights. Thermoplastic polymers and their composites have become the most in-demand materials in recent times as they provide numerous advantages over thermoset composites. Thermoplastic polymers have a high damage tolerance, high impact resistance, recyclability, formability, weldability, repairability, and cost-effectiveness productivity compared with thermoset composites. Thermoplastic polymers and composites are widely used in automotive, aerospace, electrical and electronics, industrial, and medical applications. Thermoplastic composites are estimated to grow from USD 28.0 billion in 2019 to USD 36.0 billion by 2024. High-performance thermoplastic materials are used in conjunction with a multitude of manufacturing processes such as injection molding, thermoforming, prepreg, liquid injection processes (especially reactive thermoplastics), automated tape placement, filament winding, pultrusion, additive manufacturing, and other processes. The material limits, design, and assembly requirements, as well as the processing constraints, are significantly important for the realization of novel product development using a manufacturing process by simultaneously optimizing the reliability, safety, and other performance-related issues. The current thermoplastic material systems and the manufacturing techniques still have plenty of room for optimization and advancement.

This Special Issue aims to present the latest scientific and technical advances in thermoplastic materials and their composites, processing, characterization, product development, manufacturing process parameter optimization, and modeling. Manuscripts pertaining to both scientific and applied research on thermoplastic polymers and composites are highly welcome.

Electronic devices are sensitive to electromagnetic (EM) emissions, and require electromagnetic shielding protection to ensure good operation, and prevent noise, malfunctioning, or even burning. To ensure protection, it is important to develop suitable material and design solutions for electronic enclosures. Most common enclosures are made with metal alloys using traditional manufacturing methods. However, using thermoplastic composites combined with additive manufacturing (AM) technologies emerges as an alternative that enables the fabrication of complex parts that are lightweight, consolidated, and oxidation- and corrosion-resistant. In this research, an AM technique based on material extrusion was used to print 2 mm-thick specimens with a multi-material made of micro-carbon fiber (CF)-filled polyamide that was reinforced at specific layers using continuous carbon fibers stacked with a 90° rotation to each other. The specimens’ electromagnetic shielding effectiveness (EMSE) was evaluated in the frequency band of 0.03–3 GHz using the coaxial transmission line method. Depending on the number of CF layers, the EM shielding obtained can be up to 70 dB, with a specific shielding up to 60 dB.cm3/g, predominantly by the absorption mechanism, being 22 times higher than without the CF layers. These findings promote this innovative approach to lightweight customizable solutions for EM shielding applications. Full article
