A continuous 20meter long cable tray must be installed in an aircraft compartment. The tray must combine high strength, lightweight and must be electrical insulating. Which class of material would you suggest and which manufacturing process to manufacture this cable tray component? You should justify your material and process selections.

Recommend the types of materials that should be used in the fabrication of a wind turbine for power generation. Discuss any four mechanical, physical and chemical properties of these type of materials and discuss some other application of these type of materials other than the above application.

Hello Sir.Good Evening I have a question in my home work related materials polimer lesson. The following below is my question. Please advice, thank you so much. "Explain how the relationship between temperature and the tensile strength of polymers ?"

For a glass/epoxy lamina with a 70% fiber volume fraction using the properties in the tables provided below (a) Find the ultimate tensile strength. (b) Find the minimum and critical fiber volume fractions related to (a). (c) Find the compressive strength when the matrix undergoes extension mode and when the matrix undergoes shear mode, which one controls the compressive failure? Property Axial modulus Transverse modulus Axial Poisson's ratio Transverse Poisson's ratio Shear modulus Axial tensile strength Axial compressive strength Transverse tensile strength Transverse compressive strength Shear strength Epoxy Glass Units 3.4 85 GPa 3.4 85 GPa 0.3 0.20 0.3 0.20 1.308 35.42 GPa 72 1550 MPa 102 1550 MPa 72 1550 MPa 102 1550 MPa 34 35 MPa

A.1 (i) (ii) What other materials properties would you need to consider in choosing the best lightweighting option at higher service temperatures (400-750.C)? Based on the information you have, and your own knowledge from the course, which materials system would you now recommend for this higher temperature service application? Justify your answer. Explain why over the last 20 years, metal matrix composites have attracted much interest but have yet to achieve their full potential. Give examples of the use of metal matrix composites in automotive applications.

Use brief sentences, sketches or calculations to answer the following questions:

Give some examples of commercial products which are laminar composite structures.

Describe the structural differences between Kevlar and Nomex (both aramids) that are responsible for their different mechanical characteristics.

Define the term perfectly plastic?

I need the solution of this question,please. Prove that the area fraction equal to volume fraction when using aligned fibers in composite materials.
