GRP parts which require heat resistance.
- Spray-up Application
Glass fiber roving and catalyzed resins are sprayed on mold surface with a chopper gun. Any air trapped after spraying is released with a roller.
Spray-up production steps:- Apply wax-based release agent on mold surface (ref. mold release waxes)
- Apply gelcoat film with 500-800 micron thickness
- Check chopper machine pressure and peroxide ratio
- Spray polyester resin and chopped fibers with spray gun
- Continue spray-up until obtaining desired thickness
- Release trapped air with roller
- Hand Lay-up Application
Hand lay-up production methods offer design flexibility, are low cost and a good choice for many producers. It is an ideal method for low quantity part manufacturing. Hand lay-up
production methods allow flexibility with part shapes and lamination design and have lower mold costs compared to other production techniques. Additionally, it is possible to obtain
desired mechanical properties with different fiber resin ratios.
Hand lay-up production steps:- Apply mold release agent on mold surface
- Apply 500-800 micron gelcoat film on mold surface
- After gelcoat has reached a certain cured state, lamination steps can begin
- Composite part should be trimmed after demolding
