Special Issue Information

Dear Colleagues,

The composite is the millennium strategy for the future of human existence. A well-organized social structure, social composite or nature–natural composite is the road to success.

The biopolymers and the biocomposites through which a product is intelligently recreated starting from the existential principle of life represent the natural engineering solution of life in the conditions of a dynamic globalized system with unpredictable demands.

According to the strategies of engineering existence adapted to an existential dynamism, the engineering directions for the development of the field of engineering of bioplastic and biocomposite products are taken into account.

Materials’ progressive substitution using biodegradable polymers and biobased polymers for circular economy is now wide diffused, with applications using bioplastic (novel often biodegradable, i.e. PLA, PHA, PBS, PBAT, starch blends, etc.), bioplastic durable drop-ins (bio-PET, bio-PE, bio-PA, bio-PUR, bio-PP) involved all the industrial world. Agriculture (mulch film), the food industry, food packaging and consumables, the packaging industry, the toy industry, household items, consumer goods, fuel cell, sports equipment without neglecting biodegradable polymers in medicine (spiral for removing lime deposition, locating pins for fracture, etc.), and additive manufacturing applications are just some examples.

Research development on biocomposites and biocomposite products concerns organic constituents of the composite product: bio-resin, reinforcing element, gel-coat, wax, and technologies of bioproducts.

Manufacturing of biocomposite products to be introduced in the circular economy is an interesting challenge for the automotive industry with energy saving in cars, the aviation industry, energy solar cell field, and sports equipment manufacture. Interface element production with green synthesis of bacterial cellulose composites could increase the mechanical performance of biocomposite products. Research on resin-fiber adhesion can lead to redefining the allowables in many structural applications composites. The current deep capability to virtualize a product design, by means of CAE, encloses all presented materials, and structural performance can be increased, while structures in general can be optimized.

Lastly, new design concepts based on biomimetic materials and products merge well with polymeric and biocomposite material applications.

The development of environmentally benign silicone composites from sugar palm fibre and silicone rubber was carried out in this study. The mechanical, physical, and morphological properties of the composites with sugar palm (SP) filler contents ranging from 0% to 16% by weight (wt%) were investigated. Based on the uniaxial tensile tests, it was found that the increment in filler content led to higher stiffness. Via dynamic mechanical analysis (DMA), the viscoelastic properties of the silicone biocomposite showed that the storage modulus and loss modulus increased with the increment in filler content. The physical properties also revealed that the density and moisture absorption rate increased as the filler content increased. Inversely, the swelling effect of the highest filler content (16 wt%) revealed that its swelling ratio possessed the lowest rate as compared to the lower filler addition and pure silicone rubber. The morphological analysis via scanning electron microscopy (SEM) showed that the sugar palm filler was evenly dispersed and no agglomeration could be seen. Thus, it can be concluded that the addition of sugar palm filler enhanced the stiffness property of silicone rubber. These new findings could contribute positively to the employment of natural fibres as reinforcements for greener biocomposite materials. Full article

Self-healing polymers are a new class of material that has recently received a lot of attention because of the lifespan improvement it could bring to multiple applications. One of the major challenges is to obtain multifunctional materials which can self-heal and exhibit other interesting properties such as protection against corrosion. In this paper, the effect of the incorporation of an aminosilane on the properties of a self-healing organic polymer containing disulfide bond is studied on films and coatings for aluminium AA2024-T3 using simple one step in situ synthesis. Hybrid coatings with enhanced anticorrosion properties measured by EIS were obtained thanks to the formation of a protective oxide interface layer, while exhibiting wound closure after exposition at 75 °C. The thermal, mechanical and rheological properties of the films with different aminosilane amounts were characterized in order to understand the influence of the slight presence of the inorganic network. Stiffer and reprocessable hybrid films were obtained, capable to recover their mechanical properties after healing. The nanocomposite structure, confirmed by TEM, had a positive effect on the self-healing and stress relaxation properties. These results highlight the potential of sol-gel chemistry to obtain efficient anticorrosion and self-healing coatings. Full article

Multi jet fusion (MJF) technology has proven its significance in recent years as this technology has continually increased its market share. Recently, polypropylene (PP) was introduced by Hewlett-Packard for the given technology. To our knowledge, little is known about the mechanical properties of polypropylene processed by MJF technology. During this study, standardised specimens were printed under all of the major orientations of the machine’s build space. Each of these orientations were represented by five samples. The specimens then underwent tensile, bending and Charpy impact tests to analyse their mechanical properties. The structural analysis was conducted to determine whether PP powder may be reused within the MJF process. The mechanical tests showed that the orientation of the samples significantly influences their mechanical response and must be carefully chosen to obtain the optimal mechanical properties of PP samples. We further showed that PP powder may be reused as the MJF process does not significantly alter its thermal and structural properties. Full article
