Read the mind map as text

Families 1

Property selection: Strength, stiffness, toughness are distinct
Physical property meanings: Density, absorbency, fusibility, conductivity
Strength and hardness: Load failure versus surface indentation
Working properties: Malleable compression; ductile wire; elastic recovery

Families 2

Paper and board families: Fibre sheets; match surface and structure
Timber families: Botanical groups; natural and manufactured timber
Metal families: Ferrous iron; alloys tailor properties
Polymer families: Thermoplastics soften; thermosets cross-link

Families 3

Textile families: Fibre source and fabric structure both matter

Selection 1

Selection criteria: Justify a compromise for a specific product
Forces and stresses: Pull, squeeze, bend, twist and slide
Reinforcement: Layer, fold, rib, web or interface
Six Rs: Rethink, refuse, reduce, reuse, repair, recycle
