Technical principles

to bind the reinforcement together and protect it

to allow the reinforcement to move freely

What is the main job of the matrix in a composite material?

to change the colour and improve the surface properties

What is the purpose of adding additives to papers and boards during production?

Which process uses heat and pressure to create a denser and smoother material?

by making papers thinner and more flexible

How can chemical treatments be used to enhance paper and board materials?

it can maintain its shape under normal conditions without breaking

it can resist environmental changes like temperature and moisture

the cost-effectiveness of building a structure

What does 'structural integrity' refer to in materials and structures?

one material bonded to at least one other

high pressure and heat is used to compact fibres

a fluted layer is used to provide strength

folded sections that allow expansion and improve load distribution

used for flat packages to hold their shape, without the need for glue

adding walls or ridges to a material to improve its strength

Match the following structural integrity techniques to their definition:

Materials are chosen based on their physical and working {{}}.

Which of the following is a working/mechanical property of a material?

The ability of a material to resist breaking when a force is applied is called {{}}.

Match each material with its primary working/mechanical property:

physical properties/characteristics relate to how a material looks and feels

working/mechanical properties describe material behaviour when exposed to forces

hardness is a physical property/characteristic

elasticity is a working/mechanical property
