Development of strontium ferrite/polyamide 12 and neodymium iron boron/polyamide 12 composites using additive manufacturing
Abstract: Polymer matrix composite materials with magnetic properties obtained by the addition of micron-size particles of neodymium iron boron (NdFeB) and strontium ferrite for fused filament fabrication (FFF) are becoming attractive because of their potential applications in the health and automotive industries. Additionally, the design flexibility and low cost of additive manufacturing processes encourage the scientific community to create the materials and understand the properties of the parts obtained with such …

Synthesis of Novel Hybrid Biocomposites and Experimental Investigation of Mechanical Properties
Abstract: As industries increasingly adopt additive manufacturing, the demand for materials that offer better mechanical properties and functionality is on the rise. The purpose of present research work is to develop a novel hybrid biocomposites for 3D printing applications. The acacia bark, waste powder obtained from wet mahanarayan oil consisting of herbs and other bio filler was added in polylactic acid (PLA) for synthesis of hybrid biocomposites filament by twin screw …

AI-Driven Inverse Design of Functionally Graded Bio-Nanocomposites for Sustainable High-Barrier Packaging
Abstract: Multilayer plastic packaging realizes high barrier performance through laminated heterogeneous structures, but the heterogeneous structure has severe end-of-life challenges caused by the interfacial incompatibility of materials and the poor recyclability. This study proposes the inverse design of functionally graded PLA-nanoclay composite films by reinforcement learning as a monolithic alternative to traditional multilayer systems. Twin-screw extrusion is designed as a continuous control Markov decision process, and proximal policy optimization (PPO) is …

Performance Enhancement of COC-Modified LLDPE Films: Optimization of Stiffness, Tear Resistance, and Barrier through Plasma Surface Modification
Abstract: This study explores the development of high-performance packaging materials by blending commodity Linear Low-Density Polyethylene (LLDPE) with engineering cyclic olefin copolymer (COC) as a performance modifier. To leverage the processability of LLDPE alongside the structural rigidity of COC, blends were prepared at various weight ratios (95/05, 90/10, 85/15, and 80/20) using twin-screw melt extrusion, followed by the production of films and sheets via blown film extrusion and compression molding. The …

Studies on Mechanical, Optical, Barrier Properties and Characterization of LDPE-PLA Blend Films with Micro Clay
Abstract: Low density poly ethylene (LDPE) and Poly lactic acid (PLA) in the ratio of 70:30 wt% were blended along with ethylene glycidyl meth acrylate (EGMA) as compatibilizer (2.5%), benzophenone as photodegradable additive (1%) and microclay (1,3,5%) as filler. Blending took place in a twin-screw extruder and then the resulting blend was processed into a film using blown film extrusion. Mechanical, optical, barrier and degradative properties of film were tested as …

Fabrication and Characterization of Almond Skin Powder Reinforced PLA Based Composite Filaments for Fused Filament Fabrication
Abstract: Researchers around the globe are increasingly utilizing recycling methods to address waste generated from polymers, spurred by the dire need to deal with environmental challenges promoting sustainable practices. Polymers are having highly-stable long-chain polymer structure which makes it difficult to degrade easily posing many environmental and health challenges, hence, recycling of the polymers is the sole method to mitigate harmful effects. However, there has been relatively little focus on producing …

Preparation and Characterization of Polyolefins/Inorganic Nano-Filler Nanocomposites via Melt Extrusion Process
Abstract: This work used the melt-mixing method followed by compression molding to create nanocomposites of polyolefins, such as high-density polyethylene and linear low-density polyethylene, packed with both surface-modified and unmodified nano-calcite. The study examined the effects of varying concentrations of nano-calcite, which had been modified using isopropyl tri-(dioctylpyrophosphato) titanate, on the mechanical properties, morphological characteristics, and flow behavior of the resulting nanocomposites. A corotational twin-screw extruder was utilized to manufacture three …
