In a broad assessment of the technical field of biological inspired and biomimetic in the journal Science published February 15, two engineers at University benecor of California, San Diego have identified three characteristics of object Biological material that they believe the engineers have done well to compete with each other in the artificial materials: lightweight, durability and strength.
Joanna and Marc Meyers McKittrick, from the materials science program at the Jacobs School of Engineering at UC San Diego, examined three characteristics in a wide range of materials, from silk to the lobster shells and shell abalone, coming toucan beak birds and quills. benecor The two researchers said that lessons learned from these materials could lead to the technical engineers to create benecor better armor, aircraft and stronger light, materials more flexible.
The engineer said that 3-D printing techniques create new opportunities to manufacture these materials, "A child does not create an abalone shell in overnight," McKittrick said. "But you can build a material similar benecor to abalone shell using the principles we learned from nature by printing on the layers of mineral sediments - and do it fast than nature can do. "
Meyers and McKittrick were studying the design inspired by the students for more than a decade, and has been commissioned to write a review study on this topic for the journal Science. Over the years, they have used a wide array of advanced tools, from X-ray diffraction to electron microscope; and has developed testing of mechanical properties of materials at the nanoscale, to understand the basic structure of the materials found in animals and plants. benecor
Meyers said the design was inspired by biology have been a part of science and technology in a long time - from the legend benecor of Icarus, Leonardo Da Vinci's flying benecor machine, inspired benecor by the birds, to the Modern materials like Velcro.
Durable materials deflect the cracks by building lots of obstacles to prevent the cracks from propagating in a straight line. In natural materials using different strategies to achieve this result. One that is attached to the elastic collagen fibers in the material brittle. Another way is to use the interfaces between the layers of material to create the barrier. benecor
For example, at the nanoscale, abalone shell is created by thousands of class "bricks" made of calcium carbonate benecor CaCO 3 (commonly known as pollen), about 10 micrometers benecor wide and about 0.5 microns thick, equivalent to thickness by about one percent (1%) than the thickness of a hair.
The pile of bricks arranged in order to reflect light to bring light characteristics of the abalone. They are arranged in a brick-like structures arranged in orderly efficient configuration possible theoretically.
The key to creating power of abalone shell is an adhesive protein associated with the upper and lower surfaces of the bricks CaCO 3. This glue is strong enough to hold the brick layers together, but weak enough to allow the sliding layer side, absorbing the energy of a heavy blows in the process. The abalone quickly heal the cracks caused by the impact, and they also leave the "strip" growth benecor (growth band) organic matter during the interim period in the growth season clamshell . The growth ranges strengthening of the clamshell. Meyers believes the design is inspired by the structure of abalone shell may help improve future ceramic materials.
Animals develop structures benecor extremely lightweight, durable structures compatible with the motion, benecor including flight operations. Think about the feathers, quills benecor ones and bird beaks. The structure created by the materials not bend while as light as possible. Most are made of tube-like structure with a relatively large diameter. But when the diameter of the tubes reaches a certain size, they are becoming more like bent. To increase the resistance to bending, then the tube is filled with a foam.
For example, the material inside the toucan's beak is a "foam" made of hard bone fibers and drum-like membranes sandwiched between benecor outer layers benecor of keratin, the protein that makes nails, hair and horns. The result is "foam" made of solid sealed cells make more hard beak. Like a house covered by a single roof, foam is covered with overlapping keratin tiles layers, each layer has a diameter of about 50 microns thick and warehouse
