Special Issue Information

Dear Colleagues,

A strong understanding of different materials and their manufacturing processes is essential in today’s ever-expanding world. Producing materials with unique features that can aid in manufacturing is vital for succeeding in the industrial world. Advancements in technologies have provided a wide range of materials that have replaced most of the basic materials once used for wide-scale production. The wide-scale production of composite materials has enabled the field of unconventional machining processes to significantly contribute to the manufacturing industry. Such unique features have created innumerable opportunities for people to implement innovative ideas in this field with enthusiasm. Fiber-reinforced composite materials open up the possibility of enhancing polymers' mechanical and thermal properties. This provides the opportunity to explore its potential in various applications, including automotive, biomedical, aerospace, sports and other small- and large-scale applications.

We are pleased to invite your very valuable contributions. This Special Issue aims to create a collection of at least 10 articles on the topic of the preparation, properties and engineering application of fiber-reinforced thermoplastic polymer composites in the open access journal Polymers (ISSN 2073-4360).

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: polymer-based fiber-reinforced composite materials; the processing and characterization of polymer composite materials; additively manufactured composite materials; and the mechanical and thermal property analysis of polymer composite materials.

We look forward to receiving your contributions.

The aim of this study is to determine the hydrothermal recycling of medium-density fiberboard (MDF) wastes using zinc chloride (ZnCl2) as an acidic catalyst to obtain reinforcing fibers for epoxy-based composites. For this purpose, during the hydrothermal recycling process (110 °C, 0.4 bar), zinc chloride solutions with different concentrations (0% to 30%) were applied at different time intervals (20 to 60 min). The recycled fibers were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope-energy dispersive spectrometry (SEM-EDS), carbon (C) (%), hydrogen (H) (%), and nitrogen (N) (%) contents, and fiber classification. The fibers were added as a filler (1% w/w) to epoxy composites. The compression strength and of the epoxy composites as assessed and differential scanning calorimetry (DSC) characterization was performed. According to the results, nitrogen content decreased with increasing ZnCl2 concentration. Furthermore, the fine fibers ratios increased with increasing treatment time. The results suggest that recycled fibers can be used as a filler in epoxy composites; however, a long treatment time adversely affects the compression strength of epoxy composites. Full article
