d) A number of [0]s and [0,90]s CFRP test specimens were made from prepreg material with the following properties: Fibre strength, of = 3250 MPa Fibre modulus, E₁ = 195 GPa Matrix strength, m = 35 MPa Matrix modulus, Em = 3.8 GPa Volume fraction of fibres, Vf = 0.65 Calculate the tensile strength, oc, and the tensile modulus, Ec, in the 0° and 90° directions, using the simple "rule of mixtures" approach for both the [0]s and [0,90]s specimens.
In 1907 a janitor called Murray Spangler put together a pillowcase. a fan, an old biscuit tin and a broom handle. It was the world's first vacuum cleaner_ One year later he sold his patented idea to William Hoover whose company wont on to dominate the vacuum cleaner market for decades. especially in its United States homeland. Yet between 2002 and 2005 Hoover's market share dropped from 36 per cent to 13.5 per cent, Why? Because a futuristic looking and comparatively expensive rival product, the Dyson vacuum cleaner, had jumped from nothing to over 20 per cent of the market. In fact, the Dyson produce dales back to 1978 when James Dyson noticed how the air filter in the sprayfnishing room of a company when; he had been working was constantly clogging with powder particles (just like a vacuum cleaner bag clogs with dust). So he designed and built an industrial cyclone lower, which removed the powder particles by exerting centrifugal forces. Thy question intriguing him was, could the…
Compression molding is a manufacturing process in which the molding material is preheated then placed in an open mold cavity where the compressive action of the punch forces the polymer into the desired shape as shown in the figure below. Based on your understanding of the behavior of polymers, which of the statements below regarding compression molding of polymers are accurate? Punch Cavity C. -Upper mold half Charge 41 (1) -Lower mold half Knock-out pin V, F |x.F (2) and (3) Molded part a. Lower operating temperatures are more desirable as they reduce viscosity making it easier to fill the cavity b. This process can only be used for thermosets as they can thermally cure from monomer state This process can be used for both thermosets and thermoplastics as they can both be thermally shaped d. This process is suitable for rubber, PVC and polymethyl methacrylate
A polymer has creep behaviour that can be represented as a power law equation: e = 0 (Jo + Jit") where J, is 0.5 GPa1, J1 is 0.45 GPa's 0.3 and n is 0.3 (with t in seconds). A component of this material has the following applied stress history: There is no stress before t = 0 A positive (tensile) stress of 8 MPa is applied from t = 0 for 4 hours From t = 4 hours to 6 hours, the stress is compressive stress of 2 MPa The stress is then removed. What will the strain in the material be at t = 9 hours? Enter your value as a number to 4 decimal places. You have a 2% error margin with this.

(6) There are many kinds of polyethylene foam, each with different properties. The low density polyethylene foams (as seen in this video) are very flexible. Remember: in solid mechanics, "flexible" just means that in comparison to other materials, the material deforms quite a bit, relative to the stress. For torsion, the material property that relates to stiffness is the shear modulus (or modulus of rigidity), G. We'll say that G = 6 MPa. a) Complete the FBD. b) Compute the shear stress at Point B. c) Illustrate it on a stress element. d) Report the shear strain at B (in radians). e) Compute the rotation of the top plane. f) Compute arc length s.
