Using Rubber Shapes to Teach Structural Behavior

Description:

Rubber shapes can be used to teach structural behavior and can reinforce past discussions on member behavior. These small objects can be used in all types of classes, including basic statics, Mechanics of Materials, and concrete and steel design. The various properties of these structures can be demonstrated with rubber shapes, such as their elongation, strength, and tensile modulus. Students can experience this behavior by holding the pieces in their hands. – PowerPoint PPT presentation

  • Rubber shapes can be used to teach structural
    behavior and can reinforce past discussions on
    member behavior.
  • These small objects can be used in all types of
    classes, including basic statics, Mechanics of
    Materials, and concrete and steel design.
  • The various properties of these structures can be
    demonstrated with rubber shapes, such as their
    elongation, strength, and tensile modulus.
  • Students can experience this behavior by holding
    the pieces in their hands.

  • They can be used for various purposes, from
    electrical insulation to insulating materials.
  • Depending on the application, these shapes are
    used to prevent electromagnetic interference.
  • Due to their high electrical conductivity, they
    can prevent electrostatic discharge.
  • They can also be used to teach torsion, where a
    cylindrical shape would be more efficient than a
    rectangular one.
  • This feature of rubber shapes makes them useful
    in teaching torsional moments and axial loads.

4
  • When Rubber Shapes are designed correctly, they
    can be molded into complex geometries.
  • This is accomplished by creating a mold for the
    component that contains the shape.
  • Often, engineers will also consider the location
    of parting lines and minimum draft angles when
    designing a custom mold.
  • Once the mold has been designed, it will need to
    undergo vulcanization to make it stronger.
  • They can also be shaped into many different types
    of parts, such as bumpers, seals, and other
    applications.

5
  • Rubber extrusions are made by pushing the
    material through a die.
  • These products are available in various sizes,
    from 1" cuts to 100-foot spools.
  • These custom shapes are perfect for sealing and
    gasketing applications.
  • They are also available in a variety of
    elastomers, including natural and synthetic
    rubber.
  • There are several other advantages to the
    extrusion process.
  • They can be supplied in various cuts or in
    continuous forms, such as spools and coils.

6
  • Thermoplastic elastomers are made of polyolefin
    and are the most widely used type of rubber.
  • They are used in car parts and cushioning
    components, and they are highly flexible and
    durable.
  • However, synthetic rubbers are more expensive
    than natural rubber, so they can't be recycled.
  • The best way to recycle rubber is by using it for
    automotive applications.
  • It is an environmentally friendly material and is
    recyclable.

7
  • As long as it's used for sealing, there are many
    different types of rubber shapes.
  • There are sponge-like and dense rubbers.
  • These are both excellent for insulating and
    sealing applications, and they are used for all
    kinds of objects.
  • While these are the two most common types of
    rubber, there are other types that are more
    specific.
  • For example, silicone and foam are both made of
    synthetic rubber.
  • These are two types of materials and should be
    used in the same manner to avoid damage.

8
  • When it comes to custom rubber products,
    manufacturers can find factories that specialize
    in extrusions.
  • They have multiple extrusion lines dedicated to
    custom profiles.
  • The resulting products are generally shipped
    unprocessed and can be molded into the desired
    shape.
  • These products can be vulcanized but are usually
    shipped as-is.
  • They are then cut to size and cleared of any
    imperfections.
  • For custom rubber extrusions, the market for
    customized profiles is enormous.

9
  • Rubber extrusions are similar to molded products.
  • The process involves the force of heated rubber
    in a near-liquid state into a specially designed
    die.
  • The material swells based on the chemical
    composition and hardness of the rubber.
  • When a part is made of this material, plus/minus
    tolerances must be considered in order to prevent
    distortion.
  • These are essential for ensuring the integrity of
    the finished product.
  • In addition, a perfect rubber extrusion is a
    durable, reliable rubber product.

10
  • A rubber mold is used for various purposes, such
    as building and molding.
  • Some common uses for rubber are tires, flooring,
    and other applications.
  • In the chemical industry, the material is molded
    into all types of shapes.
  • A few examples of these products include the
    simplest, cheapest, and most durable products.
  • These materials are also highly resistant to
    impact and tearing forces.
  • This type of plastic is used in construction and
    is also useful in the construction industry.

11
  • A rubber extrusion shrinks as it goes through the
    process of vulcanization.
  • A Rubber Shape will swell more in its center than
    its outer edges.
  • This is a hallmark of a good extrusion and can be
    made into many types of custom-molded products.
  • Moreover, the material has many advantages over
    other types of materials.
  • For example, a plastic sheet can be fabricated
    into a custom-designed shape with just a few
    simple steps.
