Q

Steps of creation of composite materials (generally)

A

1) prepare a mould or former.
2) apply release agent to the mould/former.
3) apply the first resin coat to mould.
4) apply GRP matting on the top.
5) apply another coat.
6) repeat the resin coat process.
7) seal vacuum bag with work piece inside.
8) place in the oven.
9) release work piece from mould.
10) trim and finish the work piece.

Q

Glass reinforce plastic (appearance)

A

Glass fibre matting is covered with smooth plastic resin (gel coat) which sets hard with high gloss finish. It is easily coloured and complex shapes can be formed.

Q

Polyparaphenylene (Kevlar) (uses)

A

Personal armour helmets, bullet- proof vests, motor cycle safety clothing, extreme sports equipment, audio equipment, musical instruments.

17
Q

Conductive fabrics and threads (appearance)

A

A silvery, fabric or thread that can be sewn or woven. Can be layered between other fabrics.

18
Q

Conductive fabrics and threads (characteristics)

A

The thread or fabric can pass an electrical current along its length, linking electronic components. It allows for flexible and wearable control of electronic products for entertainment, safety, health and fitness.

19
Q

Conductive fabrics and threads (uses)

A

Connecting wearing inputs, process and outputs such as switches, lights, blue tooth connectivity and speakers in technical clothing, children’s soft electronic toys, wearable electronic sports equipment and anti static clothing.

20
Q

Fire resistant fabrics (appearance)

A

Varies from brand but usually closely woven textures. Most can be dyed a range of colours.
