A2 Mock Exam Flashcards
Properties of Carbon fibre
- high tensile strength
- strong for its size
- x5 stronger than steel
- 1/5 of the weight of steel
Properties of fibre glass?
- strong
- light weight
- fibre reinforced plastic
Properties of Kevlar
- strength
- thermal conductivity
What is a composite?
a material made up of 2 or more materials with different chemical or psychical properties which produce a material with characteristics from the materials it is made up of
What are composites most commonly used in?
- aeroplanes
- sport cars
Why do we use composites
- weight saving
- strength
- stiffness
Define the term innovation?
using an invention or an idea and turning it into a good or service of value to customers
Explain 3 benefits of innovation
- creates new markets in a service sector
- new ideas can open doors to ho products are sold
- leads to competitive markets as other companies strive to keep up with the current trends, which STOPS A STAGNANT MARKET FROM OCCURRING
Name an example product which has opened doors to the way we sell items?
A hoover, such as the dyson ball hoover as it was unlike any current product on the markey so had its own natural unique selling point (USP)
Define durability
The ability to withstand pressure and damage
Name a durable material
Acrylic
Define elasticity
the ability of a material to resume to its normal shape after being stretched
name an example of an material with good elasticity
rubber
what is a prototype
a preliminary version/model of the idea you want to manufacture
Suggest why prototypes are important to designers
they test if your idea works, how it looks and the safety issues that need to be assessed
suggest why prototypes are important to manufacturers
- ensure that the type of production being used is appropriate
- check faults and improvements that may need to be corrected
- to save money by making sure there are no flaws that would limit their selling capability
Define density
the degree of compactness of a substance
example of a dense material
platinum
Define thermal conductivity
the rate at which heat passes through a material
example of a material with a good thermal conductivity
copper
3 examples of composites
Kevlar
Carbon fibre
Fibre glass
define lateral thinking
solving problems using an indirect, creative response which may not be an immediately obvious response
what phrase is best linked to lateral thinking
thinking outside the box
define brainstorming
problem solving by creating spontaneous lists of words and ideas
