Using and working with polymers (AQA GCSE Design and Technology): Flashcards

Uses glass fibres to reinforce polymer resin

Resistance to breaking under tension/compression

Resistance to surface indentation or scratching

Ability to absorb energy before breaking

Ability to be hammered/pressed into shape

Ability to be drawn into wires or thin sheets

Ability to return to original shape after deformation

Ability to be permanently deformed without breaking

Thin raised sections for structural support

Triangular reinforcements at corners for strength

Strong, recyclable, mouldable, affordable polymer

Excellent insulation prevents current reaching users

Car bodies, boat hulls, canoes (strength-to-weight)

Prevents polymer sticking to mould

Hardener mixed with polymer to enable curing
