Description of Fiberglass Hand Lay up:

The parts made via Hand Layer-up FRP(Fiberglass Reinforced Plastic) are created by applying liquid resin and fiberglass mat along with gel-coat onto an open-faced mould. The fiberglass mat will be laid into the moulds and the resin will be brushed into the fiberglass mat carefully according to the temperature and humidity situations. The semi-product after demoulded will be trimmed according to the drawings. Then the parts will be cleaned and polished to be packed.

Hand Layer-up parts are lighter and perform better on high strength-to-weight ratios. The parts made from hand layer-up FRP are with one side smooth—the gloss can be above 80. Now these parts are widely used on boat hulls, auto parts, truck and tractor covers, chemical retainers, heavy equipment panels, even rubbish cabins etc.

Advantages of Fiberglass Hand Lay-Up :

Lower tooling cost for low volumes

Wide range of part size

Design features easily implemented and changed

Flexible part qualities, from strong and thick to thinner and lightweight

Can incorporate minor assemblies

Typically faster than RTM

Accurate, though resin shrinkage should be factored into design
