The emerging Additive manufacturing technologies are being adopted by different industries, which require developing new materials and procedures. Here we report the development of polypropylene (PP) based composite materials for fused filament fabrication (FFF) process with the aim of enabling fully automatic robotic repair application of plastic components in automotive industry. A key challenge in repair and joining of polyolefins, which are widely used in such applications, is understanding the interplay of microstructural features and the joining mechanisms employed to achieve a uniform and fully functional repaired components. Specifically, for components manufactured from polypropylene based material, we show that the addition of ethylene propylene diene monomer (EPDM), polyisobutylene (PIB) and carbon black (CB) successfully modifies its matrix and produces a composite material ideal for additively repairing of complex geometries found in the automotive applications.This was brought about by effective reduction of the crystallinity of the composite PP matrix from 46.2% to 34.4% and resulting in a net reduction in warpage of the FFF 3D printed samples. Further, the thermal stability of the developed composite was improved with the addition of a moderate amount of carbon filler, enabling an FFF process with higher hot-end temperatures, which subsequently allowed for tuning of the raw material's viscosity, and hence ensuring consistent deposition of molten filaments for building successive layers. Mechanical properties' analysis revealed that the addition of 10 wt.% CB increased the true stiffness (storage modulus) by 20%, the impact strength by 62%, with the drop in ultimate tensile strength of 11%.The optimal elongation at break and toughness were achieved for the samples containing 2 wt.% CB increasing these key properties by 62% and 58%, respectively. In terms of the melt flow index (MFI), as a key rheological indicator, the measured value ranged between 12.5 and 19.0 g=10 min for all compositions suitable for the FFF process. Morphological analysis of the extruded filaments and fracture surface of impact test samples showed a mesoscale interspersion of polymer phases and a

Mass production of tires and their subsequent storage after use is a serious environmental problem that is tried to be solved in various ways. One of these ways is the mixture of these old used tires (ground tire rubber (GTR)) with various thermoplastic and thermostable polymers. These blends are made by modifying the pretreatment the GTR is subjected to, the degree of devulcanization, the mixing or pressing conditions, etc. Later the mixtures are analyzed structurally and mechanically, looking for possible industrial applications for them. The present work aims to obtain materials suitable for the electric industry from the mixture of polyamide with old used tires (GTR), starting from the requirement of minimum recycling costs, that is using vulcanized GTR without any prior treatment but acting on the particle sizes with a simple and inexpensive screening. A novelty of this study is the large number of compounds analyzed, and the deep analysis these have been submitted to dielectric, mechanical, thermal and microstructure analyses to get a large number of variables in each test. Compounds were categorized as the three GTR particle sizes (p < 200 mm, 200 < p < 500 mm and

“…These endeavors aim to improve the properties of ABS and explore new possibilities for its applications in different industries. [44][45][46] According to the market share report, the market size value of ABS is USD 21.31 billion in 2021 and is expected to reach up to USD 31.20 billion in 2030 with a compound annual growth rate of 4.5%. This increasing use of ABS in industrial applications, especially in automotive applications (About 12.5% of all automotive polymers are made of ABS), brings further environmental problems since ABS is a petroleum-based product that does not decompose easily in nature.…”

Effects of the addition of hemp fiber particles on the compressive and flexural behaviors of an industrially important amorphous thermoplastic, Acrylonitrile-Butadiene-Styrene (ABS), were investigated for the first time in this study. Particles with a size of 67–500 μm were first extracted from 10% NaOH alkaline-treated hemp fibers, and then incorporated into ABS at three various weight ratios (1wt%, 5wt% and 10wt%). Compression and three-point bending tests results revealed that both the compressive and flexural modulus of ABS increase with increasing particle content, but its compressive post-yield and flexural strengths decrease as enhancing particle content. The test results also showed that increasing particle content results in a significant improvement in the compressive modulus of ABS, but a slight enhancement in its flexural modulus. The notch-impact test results revealed that the impact strength of ABS is adversely affected by the incorporation of hemp fiber particles. The FT-IR (Fourier Transform Infrared Spectroscopy) analysis results indicated that mechanical bonding is formed between matrix and natural particles rather than chemical bonding. The SEM (Scanning Electron Microscopy) results put forth that the observed decrease in both the compressive post-yield and flexural strength is mainly due to the lack of strong mechanical bonding between ABS and particles. The three-point bending test data of the materials were satisfactorily reproduced using the linear Drucker-Prager material model in Abaqus engineering software.
