Hand Lay Up ProcessHand Lay Up Process

Hand lay-up is a simple method for Hand lay-up is a simple method for composite production.composite production.A mould must be used for hand lay-up A mould must be used for hand lay-up parts unless the composite is to be joined parts unless the composite is to be joined directly to another structure.directly to another structure.The mold can be as simple as a flat sheet or have infinite curves and edges.

It is a production technique suitable for It is a production technique suitable for prototypes and low volume production of prototypes and low volume production of fibre composite material parts. fibre composite material parts. The composite part will have a nice The composite part will have a nice smooth surface on one side and a very smooth surface on one side and a very rough one on the other. rough one on the other.

Hand Lay-up ProcessHand Lay-up Process

Before lay-up, the mould is prepared with a release agent to insure that the part will not adhere to the mold.Reinforcement fibers can be cut and laid in the mold.Resin must then be catalyzed and added to the fibers.A brush, roller or squeegee can be used to impregnate the fibers with the resin.The lay-up technician is responsible for controlling the amount of resin and the quality of saturation.
