-Material selection impacts the manufacturing process by determining how easy a material is to work with and its aesthetics. For instance, plastics are lightweight and easy to form, allowing for creative design in components like dashboards and handles.
What are the considerations for choosing between leather and fabric in car interiors?
-The choice between leather and fabric in car interiors depends on the car's budget and target audience. Leather is often associated with luxury, while fabric may be chosen for its cost-effectiveness.
What challenges does material science face in the context of car manufacturing?
-Material science faces challenges in producing high-performance materials that can make cars faster, safer, and more economical. This involves meeting demands for new materials that offer improved performance values.
Why are titanium alloys being introduced in car manufacturing?
-Titanium alloys are being introduced in car manufacturing as suspension springs because they are strong, lightweight, corrosion-resistant, and can provide a high-performance value.
What role does the ease of manufacturing play in material selection?
-The ease of manufacturing plays a significant role in material selection as it affects production efficiency and cost. Materials that are easier to work with can streamline the manufacturing process.
How does the target audience influence material selection for a car?
-The target audience influences material selection by determining the priorities in terms of cost, performance, and aesthetics. Manufacturers choose materials that align with the expectations and budget of their target market.
Can you suggest a resource for further learning about material selection?
-For further learning about material selection, you can refer to the books by Ashby mentioned in the script, which are likely to provide more in-depth knowledge on the subject.

Transcripts
material selection is a fundamental part
of material science from the point of
view of product design the aim is to
select the most suitable material based
on a variety of factors such as cost
performance lifespan corrosion and wear
resistance using the example of a car
many different materials have been
carefully selected to perform different
functions the windscreen is made from
laminated safety glass this is two
sheets of glass held together by a
polymer this has been chosen so that you
can probably see and adds protection
from airborne objects so in the event of
a crash this materials design holds the
glass together after shattering
preventing it from breaking into large
sharp pieces the material tires are made
from needs to protect the rest of the
wheel from wearing down absorb shock as
well as provide a good grip of the road
surface for these reasons
rubriz chosen as it is a very versatile
cheap and durable material a tire is
more than just rubber in fact it is made
of a combination of different materials
working together for example underneath
the layer of rubber steel belts are used
as reinforcements and offer puncture
resistance like a tire the cars body is
made from many materials and panels
material selection plays an important
role on determining the material a car
body will be made from performance cars
where cost is not an issue the car body
is mainly made from carbon fiber whereas
a more budget driven car is mainly steel
or aluminium aluminium is lighter but
more expensive whereas steel is cheaper
but heavier manufacturers make this
decision based on the cost and target
audience for the car material selection
is not just about the strength and
toughness of the material how easy a
material is to make as well as
aesthetics also play a role for example
plastics are not only lightweight for
easy to form allowing designers to be
creative
hence plastics are used for dashboards
and handles equally as athletic a choice
is made between leathers and fabric
depending on the budget of the car
with a constantly evolving product
material science faces many challenges
in producing high-performance materials
to produce ever faster safer and more
economical cars to meet these demands
new materials are slowly being
introduced into car manufacturing for
example new titanium alloys are now
being used as suspension Springs as the
material is strong lightweight corrosion
resistant and can provide a high
performance value material selection is
essentially about choosing the right
material for the job
the constraints of different
applications will require different
combinations of properties but
ultimately some properties are more
important than others if you'd like to
learn more about material selection
