Papers, Boards and Timbers
Comparing paper and board types with natural and manufactured timbers through source, structure, properties, stock forms and suitable uses.
How to prepare for the GCSE Design and Technology written exam
Move from requirement to evidence, technical principle, comparison and justified decision. Use current board materials separately for the NEA and for full timed-paper rehearsal.
Core concepts
Concept 1
Paper and board performance varies with fibre, mass, layering, coating and structure; grammage and thickness are not interchangeable measures.
Exam cue: Identify whether sheet, section or natural variation is beneficial or limiting.
Concept 2
Natural timber properties vary with species, grain, moisture and defects, while manufactured boards use particles, fibres or veneers to create more predictable sheet forms.
Exam cue: Use source and structure to explain a material's behaviour.
Concept 3
Selection must link properties and stock form to use, finish, production scale, waste, sourcing and end-of-life implications.
Exam cue: Compare renewable origin with the impacts of forestry, adhesives, coatings, transport and disposal.
Risk pitfalls and guardrails
Calling every paper or timber biodegradable regardless of coating or adhesive.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Assuming manufactured board is always weaker or less sustainable than natural timber.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Confusing mass per unit area with material thickness.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Memory anchors
Grammage
Mass per unit area of paper or board, commonly expressed in grams per square metre.
Grain
The direction and arrangement of fibres in paper or timber.
Plywood
A board of bonded veneers with alternating grain directions.
MDF
A uniform sheet material made from wood fibres bonded under heat and pressure.
Corrugated board
Layered board with a fluted core that increases stiffness at low mass.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
