The carbon fiber filament winding process. This process involves winding carbon fiber filaments under tension over a rotating mandrel, with the filaments impregnated with resin as they are wound onto the mandrel. Once the mandrel is completely covered, the resin is cured.

The advent of fiber lasers has revolutionized metal fabrication by significantly enhancing cutting productivity. However, challenges such as part tipping and bowing persist, necessitating a thorough understanding of nesting principles. Read more: https://lnkd.in/evT5HwWT

Composites 101: Filament Winding Let’s get into the basics of ✨Filament Winding Process✨ Filament winding is a technique primarily used to manufacture hollow, circular, or prismatic parts such as pipes and tanks. It is performed by winding continuous fiber tows onto a rotating mandrel using a specialized winding machine. Filament wound parts are commonly used in the aerospace, energy, and consumer product industries. Continuous fiber tows are fed through a fiber delivery system to the filament winding machine, where they are wound onto a mandrel in a predetermined, repeating geometric pattern. The tow location is guided by a fiber delivery head, which is attached to a movable carriage on the filament winding machine. The relative angle of the tow to the mandrel axis, called the winding angle, can be tailored to provide strength and stiffness in the desired directions. When sufficient layers of tow have been applied, the resulting laminate is cured on the mandrel. The overall size and shape of the finished part are determined by the mandrel shape and thickness of the laminate. The winding angles will determine the mechanical properties of the composite part, such as strength, stiffness, and weight. The density of the laminate is the result of the tension of the tows during winding. The composite parts made through these methods generally have good strength-to-weight properties.

Assessing the efficiency of cathodic protection involves evaluating various environmental parameters such as structure geometry, electrolyte resistivity, and steel polarization. This study explores how these factors influence current distribution and potential attenuation, particularly focusing on the contradictory effects of resistivity. By using 3D modeling, two configurations of cathodic protection systems for storage tank bottoms are compared: one with a membrane and anodic grid system underneath, and the traditional design with peripheral anodes. #CathodicProtection #CorrosionPrevention #EnvironmentalEngineering #3DModeling #ElectrolyteResistivity #SteelProtection #EngineeringResearch #StorageTanks #IndustrialSafety #BEASY

🚀 Excited to share a recent FEA analysis of a compression test on a helmet shell made from a composite material! 🚀 I'm thrilled to showcase our cutting-edge design testing for a helmet shell, crafted from an Epoxy Carbon Fiber Composite. This advanced composite material combines woven roving cloth with epoxy resin, resulting in a total thickness of just 4mm. Each of the six layers is meticulously oriented at angles of (0°, 45°, -45°, 90°, -90°, 0°) to maximize strength while maintaining a lightweight structure. In our detailed FEA analysis, we employed a 2mm hybrid mesh composed of both triangular and quadrilateral elements. To test its durability and resilience, we applied a substantial force of 10,000N to the top of the shell. This configuration and testing ensure that our helmet design not only meets but exceeds the standards for safety and performance. Check out the video below to see the stress distribution and how our innovative material and design stand up to rigorous testing. 🎥💪 #HelmetDesign #CompositeMaterials #EpoxyCarbonFiber #FEAAnalysis #Engineering #MaterialScience #SafetyInnovation #StressTesting

We compared these joints with adhesive bonded ones of identical geometry. Initially, all joint types exhibited ideal adhesive joint behaviour at low loading levels, with a linear elastic response. However, as the load increased, hybrid joints displayed unique out-of-plane deformations near the ends of the splice plates—a feature absent in bonded joints. #Engineering #Innovation Hybrid joints demonstrated exceptional resilience under escalating loads. Despite increased deformations, the presence of bolts ensured they maintained resistance, unlike bonded joints which failed as critical cracks initiated at the overlap ends in the adhesive layer. #StructuralEngineering #MaterialsScience This study provides significant insights into the failure modes of hybrid joints, paving the way for improved modelling and dimensioning in steel structures. The #resilience of hybrid joints under higher loads underscores their potential in future constructions. #Innovation #Resilience The findings highlight the promise of hybrid joints for #stronger, more #durable #structures. As engineering continues to evolve, these insights will inspire more robust solutions, enhancing the future of steel structures. 💪✨ #FutureOfEngineering #HybridJoints #StructuralResilience #adhesive #bonding #hybrid #DIC More on adhesive bonding under https://lnkd.in/eNPpfMMu

Case Study Spotlight. 👇 We received an exciting challenge from a client looking to reverse engineer an aircraft interior panel from a competitor. Our team conducted a detailed analysis to uncover the panel’s structure, density and materials used. Using advanced imaging and Fourier Transform Infrared Spectroscopy, we identified a phenolic resin in the laminate, while SEM imaging provided insights into its decorative coating. Burn tests showed the panel’s fire resistance, and muffle furnace testing revealed the core as a lightweight paper honeycomb. Through this detailed analysis, we were able to gather critical insights into the panel's composition and performance, providing valuable information for the client! #CompositesTesting #ThermalAnalysis #Metallography #MaterialsTesting #NonMetallicsTesting #MaterialsConsultancy #Manufacturing #ReverseEngineering

Unit Cell Types 💠 Plenty of cell types out there 😮 Here 4 of them: - Beam Lattice: These are straight elements, normally of circular cross-section, which, when placed inside the unit cell 🧊, are connected to the vertices, to some point on the faces of the unit cell itself or even to other straight elements. Depending on the pattern, this can be 2D or 3D lattice. - TPMS Lattice: First of all → Triply Periodic Minimal Surface a.k.a. TPMS. This geometries are minimal surfaces and are periodic in three independent direction. This is a 3D Lattice Structure. ( ⚠️ Not clear yet? Check the comments) - Honeycomb Lattice: The Unit Cell of this Lttice Structure is a hexagon. This pattern can be found in nature more specifically in hives 🐝. This pattern is very strong and is also the best solution to optimise a circle packaging. - Stochastic Lattice: These are randomly 🎲 arranged straight elements, but not because its randomness it’s cahotic, they follow a certain logic to conform the Lattice Structure.
