.....mechanical feasibility of a hybrid Epoxy/Glass/Flax composite material for handling bone fracture fixation like fracture plates. The introduction begins with definition of 'advanced engineering composite material'. The term means combination of both strong and soft constituents that are mixed together to enable the production process leading to enhancement of properties of the matrix as well as helping in the transference of the load between strong and soft materials due to their major thermal, mechanical, physical and corrosion resistance. These materials see use in engineering applications like biomechanical, aerospace, and automotive.The study continues with the introduction noting some drawbacks to synthetic fibers, with key mention of glass and carbon. Such drawbacks include high energy consumption, non-renewability, and non-recyclability. In fact, interest has grown and shifted to use of natural fibers. Natural fibers provide manufacturers with several advantages such as ease in recycling, sustainability, easier to manufacture (requires less energy), and they are lighter and subsequently cheaper. Composite materials have seen consideration for use in fracture fixation mechanism like IM nails and other biomedical applications. The authors continue with section 2: material and experimental methods highlighting the manufacturing of Epoxy/Flax/Glass specimens.
These composite...
They are made using twelve layers of flax fibers as the core and four layers of glass fiber. The general study design included testing such as tension, Rockwell hardness tests, compression, and three point bending. The tests were performed to identify mechanical properties of the Epoxy/Glass/Fiber composite specimens. The authors examined flexural modulus, longitudinal strength, flexural strength, and Young's modulus and hardness.
The objective included determining the moisture rate absorption to see how long sch materials will degrade due to exposure over long time periods. This needs to the next section, moisture absorption tests and then followed by the next section, tension tests. The authors used ASTM standards for the tensile test experiments. They measured ultimate strain as well as ultimate strength and then calculated standard deviation along with mean value. The compression tests facilitated obtainment of the modulus of elasticity via application of linear regression to what the authors noted as linear domain of experimental stress-strain curve.
The bending tests saw experimentation on 5 specimens using the three-point bending with the final section detailing Rockwell hardness tests. The results sections showed varied results beginning with the moisture absorption test which saw a steady state after…
Nanomaterials Advances in Nanomaterials and Their Applications Nanomaterials, including carbon nanofibers and nanotubes, are being explored extensively for their use and application in multiple manufacturing domains. One of the most eager manufacturing sectors to incorporate nanomaterials into their midst is the athletics gear and sporting industries. Tennis rackets, surf, skate, and snow boards, skis, ski poles, boats, bicycles, hockey sticks, baseball bats, golf clubs and balls are all potentially transformed by the
Katunin, A., Dragan, K., & Dziendzikowski, M. (2015). Damage identification in aircraft composite structures a case study using various non-destructive testing techniques. Composite Structures, 127, 1-9. The research article shows that the application of composite structure has become increasing popular in the aerospace industry based on their unique properties, which include excellent weight ratio, strength, and corrosion resistance. To ascertain a safety of composite elements and structural integrity on aircraft, it
Tree Wind Power Generator Currently, there is a growing demand for sustainable energy sources given the rising fossil fuel prices, carbon dioxide emissions, and energy security. In apt response to this critical issue, a renewable alternative energy innovation is receiving wide spread interest and attention. This innovation entails the manufacture of energy harvesting trees to capture both wind and solar energy (Alternative Energy, 2009). The technology behind this; bio-mimicry is an
Surface irregularities are often seen when using the scanning electron microscope, but these are absent using the AFM. One such analysis is described below: Occasionally, the cartilage surface exhibits local discontinuities where an underlying fibrous network is distinguishable. Digestion of the cartilage surface with chondroitinase AC exposes this fibrous network more systematically so that the individual fibers are visualized with great clarity by AFM. When imaged at higher magnification, these
This product may provide "long-term electrochemical protection" against the deterioration of the steel rebar in the concrete, the article states. When this "pressure-sensitive" zinc-hydrogel solution is applied an "iconic current" is conducted. Wires run through the rebar grid once the concrete is covered thoroughly with the adhesive gel. The bottom line here is the zinc slowly corrodes rather than the rebar. Ironically, the 3M companies developed this zinc hydrogel
Steps were also taken to organize a stock market in Lahore (Burki, 1999, pp.127-128). Also organized during this period were the Pakistan Industrial and Credit Investment Corporation (PICIC) and the Industrial Development Bank of Pakistan (IDBP), both of which were important to industrial development, obtaining "large amounts of capital from the World Bank, the former for investment in large industries, the latter in relatively smaller enterprises" (Burki, 1999, p. 128).
