Neu erschienen/just published: #DIN 6180:2024-07 #DIN6180 #Kunststoffe - Bestimmung der Beleuchtungsdiffusion - Messung der #Trübung durchsichtiger Materialien im Nahbereich #Plastics – Determination of illumination diffusion – Near-distance #haze measurement for #transparent #materials Can be found here https://lnkd.in/d6pgisHM This document specifies a method for measuring illumination diffusion (ID), an optical property resulting from the scattering of light, in transparent and largely colourless plastic films and packaging. Two parameters are quantified, namely ID #opacity, which results from the scattering of light at a wide angle, and ID sharpness, which results from the scattering at a low angle. If you are looking for a device that can help you measure that - ask me about the Rhopoint ID! https://lnkd.in/eBbDevyU (side info: - did you know that after a 100 years, "Beuth Verlag" now is DIN Media? more information to be found on the DIN Media homepage)

What is the future of aerospace lightweightíng ? - Functional Integration in composite wing structures holds the key to attaining further weight reductions. - This integral aerodynamic structure combines fiber-friendly design with good manufacturability. To manufacture this structure, the VPH2.0 project requires a multisided defined mold with internal core modules. The resultant process approach was based on the Resin Transfer Moulding (RTM) principles, which eliminates the need for laminated reinforcements in connection elements such as bolts and rivets. Monitoring the process with specialized sensors is necessary to detect deviations early and implement corrective measures. However, conventional monitoring of the manufacturing process of fiber composite components does not offer real-time information on the component's status. The claim for an individual digital component twin goes far beyond monitoring and documentation. For each manufactured component, the status (filling level, crosslinking) is spatially resolved and monitored in real-time. Specialized sensors measure the impregnation and subsequent gelation of the resin system. Ultrasonic sensors measure acoustic properties, fiber optic sensors detect strains in the laminate spatially resolved, and dielectric sensors measure changes in permittivity. #fibercomposites #structuralintegration #functions #sensors #lightweight #Vielholmerflap #RTM #simulation #industry4.0 https://shorturl.at/rJQXZ

faster deaeration can lead to faster, cleaner, and more weight accurate, filling; saving time, effort, and money. as ever dy-pack lead the way

In this video, we present to you the precise casting process of liquid aluminum in slow motion, utilizing a 3D-printed sand mold. As the pouring basin fills with slightly glowing, liquid aluminum, the inlet is sealed by a hand-held plug to ensure exact and controlled pouring. Once the molten metal reaches the required fill level, the plug is removed, allowing the liquid metal to flow evenly into the mold. This process minimizes unnecessary air inclusions and surface turbulence. #PrecisionCasting #MetalCasting #LiquidAluminum #SlowMotion #3DPrinting #SandMold #Metallurgy #Manufacturing #FoundryProcesses #AluminumPouring #ControlledPouring #MetallurgicalEngineering #MoldMaking #IndustrialProcesses #ExOne #JohnCampbell

Pulverisation of catalyst honeycombs for further analysis Vehicle catalytic converters contain precious metals that can be worth recycling. Milling the catalyst honeycombs into fine particles can facilitate the separation of the catalytic material from other components. This separation is crucial for recycling the valuable catalyst material effectively. Sample preparation can be carried out with cutting and planetary mills.

Wangling's #F4BTM series laminates are composed of fiberglass cloth, nano-ceramic fillers, and PTFE resin, which are then subjected to a strict pressing process. These laminates are based on the F4BM dielectric layer, with the addition of high dielectric and low loss nano-level ceramics. This results in several performance improvements: 1. Higher dielectric constant 2. Improved heat resistance 3. Lower thermal expansion coefficient 4. Higher insulation resistance 5. Better thermal conductivity 6. Maintained low loss characteristics The F4BTM and F4BTME variants share the same dielectric layer but use different copper foils. F4BTM is paired with ED (Electrodeposited) copper foil, while F4BTME is paired with reverse-treated (RTF) copper foil. This offers the following advantages: 1. Excellent PIM (Passive Intermodulation) performance for F4BTME 2. More precise line control 3. Lower conductor loss The F4BTM series offers a wide range of features and design flexibility, with a dielectric constant (DK) range from 2.98 to 3.5. The addition of ceramics further enhances its performance, making it suitable for demanding applications. The F4BTM laminates are available in various thicknesses and sizes, catering to different project requirements while offering cost savings. The commercialization and suitability for large-scale production make this material a highly cost-effective choice. Additionally, F4BTM exhibits radiation-resistant and low out-gassing properties, ensuring its reliability even in challenging environments. The F4BTM #PCBs are utilized in a variety of applications, including: - Antenna - Mobile Internet - Sensor Network - Radar - Millimeter Wave Radar - Aerospace - Satellite Navigation - Power Amplifier

#WL-#CT series laminates are high-frequency materials that combine hydrocarbon resin, ceramic, and glass fiber cloth in a thermosetting resin system, providing low loss performance and meeting high-frequency design requirements. The combination of hydrocarbon resin and composite ceramics in this series results in low loss, high temperature resistance, temperature stability, stable dielectric constant, low thermal expansion coefficient, and a high TG value exceeding 280℃. The dielectric constants of these series range from 3.0 to 6.15, with a dissipation factor ranging from 0.003 to 0.005. For instance, WL-CT338 exhibits a DK value of 3.38 and a DF value of 0.0029. WL-CT338 #PCBs offer versatility and can be applied in a wide range of applications, including base station antennas, satellite antennas, automotive radar systems, WIMAX antennas, distributed antennas, and miniature patch antennas etc.

Vacuum brazing viewports at high temperatures creates stress in the optic during the cooling down process. This stress is caused by the different expansion / contraction rates of the optical material and the metal carrier. Materials are chosen to match their expansion coefficients as much as possible, but there are limits on what can be used. The stress causes the optic to change shape in a variety of ways, which affects the overall flatness of the optic. The overall effect on the transmitted wavefront error (TWE) is not as bad as expected as the parallelism is preserved between the two optic faces. Torr Scientific offer high-flatness fused silica viewports, ranging from λ/10 to λ/20 @ 632.8nm, using a bonding process as an alternative to vacuum brazing. The optics are sealed into the flange assembly at room temperature, so there is no residual stress occurring as part of the sealing process. The optic retains the original flatness as manufactured. Bonded viewports have a maximum bake-out temperature of +120°C compared to +200°C for a brazed equivalent. It should also be noted that polishing fused silica optics to a very high flatness requires thicker optics in the case of the λ/20 versions, particularly with the smaller optics CF16, CF38, & CF64 (1.33″, 2.75″, 4.5″ Conflats).
