composites + papers boards Flashcards
what is a composite?
a material comprised of two or more different materials resulting in a material with enhanced properties
whats a manmade wood based composite material also called?
manufactured board
carbon fibre reinforced plastic: properties and uses and compositions?
carbon fibres mixed with polyester resin
- lightweight, corrosion resistant, tough, hard, good compressive strength, low thermal expansion
- sports equipment (bicycle frames etc)
glass reinforced plastic: composition, properties and uses
glass fibres mixed with polyester resin
- lightweight, corrosion resistant, tough, hard, low thermal expansion, good compressive strength
- boat holes, kayak shells, sport car bodies, locomotive train cabs
MDF
compressed wood fibres
two smooth faces, available in standard grain or veneered with layer of timber, good strength in all directions, easy to cut and shape
model or mould making, flat pack furniture, cabinets
hardboard
compressed wood fibres
one hard shiny smooth surface, does not split easily, tough
furniture inserts
chipboard
wood chips compressed with a resin (eg urea formaldehyde)
good strength in all direction’s, easy to cut but can chip on a cur edge , not generally attractive in basic form
often veneered or covered with laminate, flatpack furniture etc
plywood
thin layers if wood placed at 90 degrees to each other, additional resin sometimes
good strength in all directions, no grain weakness, always had an odd numbers of layers, tough
four types of drawing papers?
layout paper, tracing paper, copier, cartridge paper
layout paper
thin translucent paper with a smooth surface
sketching and quick ink or marker rendering (sketch pads)
tracing paper
translucent paper slightly thicker than layout paper
for copying images when sketching
copier paper
inexpensive general purpose, white or other colours, smooth surface mostly matte or sometimes glossy
printing photographs and images etc
cartridge paper
off white paper usually with a slightly textured surface
sketching, rendering in pencil, can be used for printing
two types of commercial printing papers?
bond and coated
bond commercial printing paper
high quality paper, bright colour holding, durable surface
letterheads, flyers, writing and typing paper
coated commercial printing paper
restricts the amount of ink absorbed into the paper, good for sharp complex images
duplex card is a coated paper with the exterior made water resistant for a glossy waxy appearance
spirit based marker rendering, photographic printing
how thick should boards be?
220 GSM
types of boards?
mounting, corrugated, foam, folding box, foil lined
What is mounting board made from?
Compressed fine cotton fibres
What is a key property of mounting board?
Produces a rigid board
List two uses of mounting board.
- Presenting artwork
- Picture mounting
- Modelling
What are the outer layers of corrugated board usually made of?
Carton board
What is the main characteristic of corrugated board?
Ability to provide protection against impact
List three uses of corrugated board.
- Protective packaging
- Model making
- Food packaging such as takeaway boxes
foam board
two outer layers of card with a foam middle core available in a range of thicknesses
mood board backing, presentation boards and modelling
folding box board
multiple layers of pulp with top layer bleached or coloured
good thickness for good printing surface
can be creased and embossed
lightweight high stiffness
packaging products, food packaging
foil lined board
board with foul apied to either one side or both sides to provide a water resistant or heat insulating layer
foil can be removed before recycling
drinks packaging, milk cartons
