We present a combined experimental/theoretical study aimed at enhancing adhesion between NiTi wire and thermoplastic polyolefin (TPO) matrix in which it is embedded. surfaces were subjected to the following surface treatments prior pull-out tests: (i) treatment with an acid etch or chemical conversion coating (ii) application of microgeometry enhance mechanical interlocking TPO matrix. Nanometer micron-scale features examined atomic force microscopy. The extent each increased was quantified....
By combining the concepts of in situ thermotropic liquid crystalline polymer (TLCP) composites and conventional fiber composites, a recyclable high-performance hybrid polypropylene-based composite was successfully developed. The recycled prepared by injection molding grinding processes. Rheological thermal analyses were utilized to optimize processing temperature process reduce melt viscosity minimize degradation polypropylene. ideal for blending found be 305 °C. influence mechanical...
Abstract The influence of γ‐quinacridone as a β‐crystal nucleating agent in injection molded isotactic polypropylene (iPP) is discussed. Samples are and characterized via polarized‐light optical microscopy X‐ray diffraction. Mold‐filling simulation used to understand the shear cooling processes during sample preparation. rate associated with quench near mold wall estimated be greater than 600 K s −1 using simulation, confirming previous studies that growth not supported at rate....
The challenges posed by flexible limp fabric material handling within automated manufacturing processes are addressed in this paper.With lightweight materials, particularly fiber composites, gaining prominence across industries, the need for effective and precise placements is deemed crucial.Traditional gripping methods often found to be lacking addressing complexities of draping, necessitating innovative solutions.The deformable, delicate, complex nature combined with intricate mold surface...
Liquid crystal polymer (LCP) composites are presented as lightweight, high-strength, thermoplastic composites. Fumed silica (FS), carbon black (CB), nanostructures (CNS), and boron nitride (BN) added to the polyphenylene sulfide (PPS) increased viscosity ratio of PPS LCP. filled with 5 wt.% FS was used optimize injection molding conditions had a ranging from 2 13. Increasing fill time s brought about highest tensile strength 99 MPa modulus 12.5 GPa, while tool melt temperatures imparted no...
Abstract A novel core‐shell continuous polymeric fiber reinforced composite with excellent mechanical performance was prepared using a dual‐extrusion process. Continuous pumping of thermotropic liquid crystalline polymer (TLCP) into polyamide 6 (PA6) via equipped circular die enabled the generation filaments structure. Microscopic analysis confirmed composition and macroscopic morphology where TLCP core surrounded by shell. The structure exhibited strong weld‐strength 3D printed parts...
An adaptive control algorithm, the self-tuning regulator (STR), was applied to injection phase of an molding machine cycle. The objective hydraulic pressure and cause it follow a predetermined profile. information previous cycle used correct controller parameters for next This computation is done between cycles. STR found superior standard proportional-integral same system when high density polyethylene injected into heat distortion temperature test mold. Both algorithms had trouble...
Held et al. [CAD&A 2016] introduced generalized weighted Voronoi diagrams as a tool to construct variable-radius offsets.We revisit this structure and provide two algorithms compute it.We also introduce skeletons of polygons closely related which inherits most properties except that its skeletal regions are always connected.Experimental results obtained by our implementation discussed.In addition offsets we demonstrate how can be used generate intricate roofs for polygonal footprints...
Junction structures and rib constructions are utilized in various applications such as lightweight designs.As well geometric challenges, using directed energy deposition metal additive manufacturing techniques to build intersections junctions has the risk of having hydrostatic residual stress that can cause distortion or failure component.In this research, stresses were measured computationally via a calibrated finite element analysis model for several junction structures, which evaluated...
