Process Hand lay-up
Also called contact moulding. It is a production technique suitable for prototypes and low volume production of fibre composite material parts. The composite part will have a nice smooth surface on one side and a very rough one on the other.

The fibres are manually placed into a one-sided gel coated male or female mould. A matrix of thermosetting resin is rolled onto the fibres using an hand roller. More layers can be added and, after drying, the composite part can be removed from the mould.

Easy to control fibres orientation. Furthermore, the process is very flexible as it can produce from very small, up to very large part of different kinds of geometry.
The cycle time per part is very long, and only small series can be produced.

Price notes The cost of the production equipment is very low, but the process is very time requiring.
Environmen- tal notes Creation: Environmental problems can rise during the working procedure. Therefore the process must be carried out carefully and paying attention to the environment.
