• Webbing

Question 10

What is Bending?

Answer 10

It is adding curves, arches or tubes to increase strength without using too much material. Example: Metal Chair

Question 11

What is Folding?

Answer 11

It adds strength through layers but also flexibility. Example: Cardboard

Question 12

What is Fabric Interfacing?

Answer 12

It adds an extra layer for strength and support. Example: Baseball Cap

Question 13

What is Lamination?

Answer 13

It is bonding two or more materials to increase a product’s strength or stability. It can also be used for aesthetics. Example: Veneer
