Epoxy mal maken op hoge temperatuur kit

If you want to produce parts using prepreg carbon fibre, the first thing you’ll need is a mould that is compatible with epoxy moulding and can take the high temperatures required to cure the prepreg without softening or distorting. 

Conventional (polyester) fibreglass moulds are generally unsuitable for use with epoxy resins, even at ambient temperature, and have a maximum service temperature of around 60°C, making them doubly unsuitable for use with epoxy prepregs. The solution is to produce composite moulds using a high temperature epoxy tooling system, which is both compatible with epoxy moulding, and able to take the high temperatures required to cure the prepreg.

Our High Temperature Epoxy Mould Making Kit is designed for those new to composites, or experienced in composites by taking their first steps into working with prepregs and provides everything necessary to create a high temperature mould from an existing part or pattern. The kit includes a highly polishable epoxy tooling gelcoat for the mould’s surface, and an easy-to-use fibrous laminating paste for the main reinforcement, as well as complimentary ancillaries. The paste in particular is extremely important in helping to avoid the problems of blistering and voiding normally associated when hand laminating moulds for high temperature use.

Dekking

The materials in the kit are sufficient to produce a mould of approximately 40cm x 40cm, depending on the depth and shape of the mould. Slightly larger moulds can be produced but this will require reducing the thickness of the main reinforcement, making them less robust.

For smaller moulds, multiple moulds can be made, and there is no requirement to use all the materials in one go.

For larger moulds, all the materials included in the kit can be purchased separately in larger quantities.

Curing and Post Curing

EG/EMP160 kan worden uitgehard tot een vormbare toestand in 24 uur bij 25C, maar in dit stadium kan bros en gevoelig voor scheuren tijdens het ontvormen van meer complexe vormen. Daarom wordt in de meeste gevallen aanbevolen om de eerste uitharding uit te voeren bij 40C (waarbij de uithardingstijd kan worden teruggebracht tot 12 uur). Het uitvoeren van de eerste uitharding bij 40C is laag genoeg om vervorming van het patroon te voorkomen, terwijl nog steeds de hars uithardt tot een voldoende niet-brosse toestand om te ontvormen zonder risico op schade.

Recommended: 12hrs @ 40C

Alternative: 24hrs (min) @ 25C - Warning: Resin will be very brittle before post-cure

In common with almost all high-temperature tooling systems, moulds made using the materials in this kit require post-curing at elevated temperatures before they can be put into service as a high temperature mould. 

In a computer-controlled oven (such as our OV301), this gradual post-cure can easily be achieved by setting a ramp rate on the cure cycle. In the case of a domestic oven, or industrial oven with basic temperature control, this gradual increase in temperature can be achieved by incrementally increasing the temperature over time. See technical datasheet for full details on laminating, curing and post curing.
