Worked Solution & Example Answer:(a) Outline two reasons for the use of carbon composite materials in the manufacture of body panels for the prototype flying taxi, AeroMobil 5.0 VTOL - Leaving Cert Engineering - Question Question 1 - 2019
Step 1
Outline two reasons for the use of carbon composite materials
Answer
-
Strength of Material: Carbon composite materials offer high strength-to-weight ratios, making them ideal for aerospace applications. This is crucial for vehicles like the AeroMobil 5.0 VTOL, where weight reduction is essential for efficiency and performance.
-
Lightweight: These materials are significantly lighter than traditional materials like steel or aluminum, contributing to better fuel efficiency and improved flight capabilities in flying vehicles.
Step 2
Describe, with the aid of a diagram, the process of flotation separation
Answer
Flotation separation is a process used to separate materials based on their density and hydrophobic properties. The basic steps in this process are:
-
Preparation of the Mixture: The mixture of materials is added to a flotation cell filled with water. Chemicals known as collectors are added to enhance the hydrophobic properties of the desired particles.
-
Introduction of Air: Air bubbles are introduced into the mixture. The hydrophobic particles attach to the air bubbles and rise to the surface, forming a froth.
-
Collection of Froth: The froth containing the hydrophobic particles is skimmed off the surface, while the remaining material sinks to the bottom. This allows for the separation of valuable substances.

In summary, flotation separation utilizes differences in surface properties to provide an efficient means of separating materials.
