Maneuverable postbuckling of microscale plate like mechanical metamaterials w...TalalSalem5

��

Architected, structural materials have been reported with promising enhancement of mechanical performance using the structural method (e.g., mechanical metamaterials MM) and the material method (e.g., composite materials). Here, we develop the extensible, plate-like mechanical metamaterials at the microscale using the functionally graded materials (FGM-MM) and the carbon nanotubes (CNT-MM) to obtain the advanced structural materials with good maneuverability over the postbuckling response. Theoretical models are developed to investigate the postbuckling response of the FGM-MM and CNT-MM subjected to the bilateral constraints, and numerical simulations are carried out to validate the theoretical results. The theoretical models are used to investigate the maneuverability of the postbuckling behaviors with respect to the material properties (i.e., the FGMs and CNTs) and geometric properties (i.e., the corrugated microstructures). The findings show that the corrugation in the MM and composition in the FGMs and CNTs assist in tuning the buckling mode transitions. The reported CNT-MM and FGM-MM provide a novel direction for programming the mechanical response of the artificial materials.

Composite materials are composed of two or more distinct materials that produce properties different from the individual components. They have advantages like high strength to weight ratio, better fatigue and toughness properties than metals, and resistance to corrosion. Composites consist of a primary matrix phase that holds a secondary reinforcing phase like fibers, particles, or flakes. The matrix provides shape while the reinforcement improves properties. Fiber reinforced polymer composites are an important class of materials.

��

This document discusses using nanofibers to generate power from tires. Piezoelectric nanofibers like PZT-5A and PVDF could be embedded in tires to convert the mechanical energy from tire deformation into electrical energy. When stress is applied to these nanofibers due to tire movement or changes in pressure, a charge is produced through the piezoelectric effect. It is estimated these nanofibers could achieve a 25% energy conversion efficiency and generate several milliwatts of power. The document also notes that sensors may be needed to avoid resonance issues from the natural frequencies of the materials not matching tire frequencies.

This presentation talks about the nano composites and its applications. Les propriétés mécaniques des nanocomposites sont différentes de celles des matériaux composites traditionnels à cause d’un rapport surface/volume élevé du renfort, et de son facteur de forme important. Le renfort peut être sous forme de particules (minéraux), de feuillets (argiles exfoliées) ou de fibres (nanotubes de carbone). L’interface matrice-renfort présente une grande surface qui est typiquement un ordre de grandeur plus grand que celle dans le cas d’un matériau composite traditionnel. Cette interface implique qu'une faible quantité de renfort nanométrique peut avoir un effet observable sur les propriétés macroscopiques du composite. Par exemple, l’ajout de nanotubes de carbone améliore les conductivités électrique et thermique d’un matériau composite. D’autres types de nanoparticules peuvent conduire à l’amélioration des propriétés optiques, diélectriques, la résistance au feu, ou des propriétés mécaniques. Also, very good science.

Designing Flex and Rigid-Flex PCBs to Prevent FailureEpec Engineered Technologies

��

Flex and rigid-flex printed circuit boards (PCBs) can be considered at the basic level some of the most complex PCBs in the industry. With that in mind, it’s incredibly easy to make a mistake, to leave something out, or to create a design that was doomed from the start. Such design failures can end up leading to an eventual failure by delamination, short circuits, damage to the flex portions, and many other things. The easiest way to circumvent these is to start at the beginning, to design with preventing failure in mind rather than trying to fix existing designs to accommodate for problems. In this webinar, we cover how to design flex and rigid-flex PCBs with failure prevention in mind to save time, money, and headaches, and what failure can look like. For more information on our flex and rigid-flex PCB solutions, visit https://www.epectec.com/flex.

Piezoelectric Tyres

1. By Pabitra Kumar Das M.Tech Materials Science

2. Polymer Films With Flexibility – synthetic rubber, phenol formaldehyde resin (or Bakelite), neoprene, nylon, polyvinyl chloride (PVC or vinyl), polystyrene,polyethylene, polypropylene, polyacrylonitrile, PVB, silicone Conductive Polymers – Polyaniline , Polypyrrole , PEDOT:PSS etc etc .. Tpes of CNT- Zigzag , armchair , chiral

3. 1. Fabricate nanocomposites with CNT as fibrous part and flexible or conductive polymers as matrix with different methods like sol gel , in situ polymerization , solution processing etc . 2. To control the temperature and mechanical or chemical bonding according to fabrication parameters . 3. Decide the functionalization of CNT with matrix according to requirered properties .

4. 1. Conductive polymers with CNT to enhance the piezoelectric properties and conduction of ions or conjugating parts .( Conductive polymers have low mechanical properties and some are brittle which may harm mechanical properties of composite ) 2. CNT with flexible polymers to give very good elastic properties with piezoelectricity . 3. Selecting appropriate polymers and CNT and choose the appropriate way for making composites . 4. Deciding to functionalize CNT or not . (Just using CNT fibre reinforced polymer matrix may cause low bonding and errors ) 5. Uniform dispersion methods for processing nanocomposite .

5. 1. Solution Processing . 2. Melt Blending 3. In-situ Polymerization . Factors that affect fabrication – 1. Homogeneous dispersion of CNT throught the matrix without destroying the integrity . 2. Good interfacial bonding in case of functionalization . 3. Choosing surface modification techniques for better dispersion

7. 1. Stress Strain analysis 2. Mechanical properties deformation limit , youngs modulus etc 3. Micromechanical analysis 4. Comparison of composites with different polymers and CNT types . 5. Resonance and poling methods with dc polarization in order to induce piezoelectricity after sintering treatments .

8. 1. Using Piezoelectric nanocomposites to embedd in tyres with specific design and to extract pressure due to gravity each and every moment by proper mechanism . 2. To store the extracted energy in a good battery (electrolytic or supercapacitors) and use it for further use . 3. Proper design of wheels to get pressure and calculations for stress strain curve to bear load limit . 4. Ways to efficiently extract the power to batteries with minimal losses . 5. Use a design of rubber and piezoelectric flexible films to give all the wear and tear to rubber and conserve the piezoelectric material .

9. Rectifiers that are used to extract electricity provide very high resistance in reverse mode (opposite to the direction of permitted current flow), the remaining PZT benders act like a disconnect in the path of electric current, that is, like an open circuit.
