Nowadays, many cooking utensils are made of polymeric materials. However, people believe that heating plastic utensils would cause harm such as releasing toxic substances. Hence, people are looking for other alternatives to replace plastic. Choose ONE cooking utensil (spatula) and identify the suitable material that will satisfy its criteria. Justify your answer. Your discussion must include the interrelationship between structure-properties-processing of the selected cooking utensil.
Give an approximate value for the tensile strength of a Boron/Aluminum composite with Vf = 0.4. Aluminum 2024 has E = 71 GPa, Poisson = 0.334, yield strength Sy = 76 MPa, strain-to-failure Ey = 22%. Boron fibers have E = 400 GPa, strength = 3.4 GPa, Poisson = 0.25.
a. Compute F1t, assuming the Aluminum matrix remains elastic up to failure. If the value found is larger than Sy, the matrix yields, thus invalidating the assumption.
b. Recompute using O1 = VfOf + (1 - Vf)Om
c. Check that the strain-to-failure is not exceeded.
Solve a b with short answer
