Changing Materials to Make Them Stronger Corrugation Lamination Strengthening Component Arrangements Changing Methods of Fastening

Corrugation Forming a material into a wave-like folds or ridges. Examples: Cardboard and metal

Lamination = LAYERS! Gluing layers together to make it stronger Kitchen countertops top layer is laminated on top of wood Plywood Glass in vehicles

Strengthening Component Arrangements Making greater uses of trusses and arches by arrangement Adding small supports for reinforcement Tie – resists tension Strut – resists compression
