The Influence of the Hybridization Process on the Mechanical and Thermal Properties of Polyoxymethylene (POM) Composites with the Use of a Novel Sustainable Reinforcing System Based on Biocarbon and Basalt Fiber (BC/BF)

Abstract

The presented work focuses on the assessment of the material performance of polyoxymethylene (POM)-based composites reinforced with the use of a biocarbon/basalt fiber system (BC/BF). The use of BC particles was aimed at eliminating mineral fillers (chalk, talc) by using fully biobased material, while basalt fibers can be considered an alternative to glass fibers (GF). All materials were prepared with the same 20% filler content, the differences concerned the (BC/BF) % ratio. Hybrid samples with (25/75), (50/50), and (75/25) ratios were prepared. Additionally, reference samples were also prepared (POM BC20% and POM BF20%.). Samples prepared by the injection molding technique were subjected to a detailed analysis of mechanical properties (static tensile and Charpy impact tests), thermomechanical characteristics (dynamic mechanical thermal analysis—DMTA, heat deflection temperature - HDT), and thermal and rheological properties (DSC, rotational rheometer tests). In order to assess fiber distribution within the material structure, the samples were scanned by a microtomography method (μCT). The addition of even a significant amount of BC particles did not cause excessive material brittleness, while the elongation and impact strength of all hybrid samples were very similar to the reference POM BF20% sample. The tensile modulus and strength values appear to be strictly dependent on the increasing BF fiber content. Thermomechanical analysis (DMTA, HDT) showed very similar heat resistance for all hybrid samples; the results did not differ from the values for the POM BF20 sample.

Polyoxymethylene/talc composite: Investigation of warpage, mechanical and thermal properties for thin walled‐injection molding applications

“…The highest melting temperature is observed in POM/3 wt% polymer composite. A similar trend was observed by Andrzejewski et al 32 on bio carbon and basalt fiber reinforced POM. It is observed that the crystalline structure increased in composite results in increasing melting point.…”

Basalt/Glass Fiber Polypropylene Hybrid Composites: Mechanical Properties at Different Temperatures and under Cyclic Loading and Micromechanical Modelling

“…The combination of two kinds of fillers in a single matrix can show advantages of both fillers. The following different combinations of fillers can be used to produce hybrid composites: banana/glass [ 12 ], kenaf/glass [ 13 ], wood/glass [ 14 ], palm/kenaf [ 15 ], and biocarbon/basalt [ 16 ]. Hybridization can help to change the properties of different composite applications.…”

A Review on Synthetic Fibers for Polymer Matrix Composites: Performance, Failure Modes and Applications

“…The necessity for Synthetic Fibers (SFs) is advancing globally, as it is a highly significant form of material for fiber-reinforced composite structures. The growing demand for lightweight and unique composite materials increases the need for SFs due to their excellent characteristics [ 1 , 2 , 3 ]. There is strong competition between Synthetic Fibers and Natural Fibers (NFs) [ 4 ].…”
