Shipping Information

Prepregs are not classified as 'dangerous goods' for transport purposes but they do need to be kept frozen when not in use. This means that for transport these products are 'perishable' and therefore must always be shipped internationally on a priority 'air' service.

Because we send the majority of 'dangerous goods' by road, it is not possible to combine prepreg and dangerous goods on the same order for delivery to countries that we usually ship to by road (most European countries). If you want to order dangerous goods items (such as resins) and prepregs then you will need to place two separate orders.

Prepreg Carbon Fibre Starter Kit

This complete starter kit has been put together as a convenient means for individuals and independent manufacturers to get started with the prepreg composites manufacturing process. The kit includes all vacuum bagging consumables, fittings and accessories, along with starter quantities of the XPREG® XC110 out-of-autoclave carbon fibre prepregs.

A video tutorial is provided below and a detailed processing guide is available from the downloads section.

Available to buy online in Regular (1m x 1.25m) or Professional (5m x 1.25m) kit sizes.

Brand new updated XPREG® version of our Prepreg Starter Kit.

This comprehensive starter kit has now been updated to include the very latest XPREG® XC110 out-of-autoclave prepreg carbon fibre. Also included in the kit is a complete range of vacuum bagging consumables and connectors to ensure a problem-free and successful start into out-of-autoclave prepreg carbon fibre.

Available in both a regular starter kit size aimed at individuals and also a full 'professional' package for small-to-medium sized businesses wanting to move into cutting-edge prepreg carbon fibre manufacture. See the specification tab for a full list of the components and quantities included in each kit.

Further Information

Compatible Moulds

To get the best results from the XPREG® XC110 prepreg system, you need to have moulds that are suitable for use at 120°C. Composite moulds made using high temperature epoxy resin/gelcoat or epoxy-prepreg are recommended. Fully mould materials include:

Suitable Moulds/Tooling

Moulds/tools should be epoxy-based composite moulds, epoxy tooling board or metal. In all cases, moulds must be temperature stable to a minimum of 85°C but ideally to 120°C.

The following mould materials are fully compatible:

  • High temp epoxy hand-layup moulds (e.g. EG160 / EMP160)
  • Carbon or glass fibre prepreg moulds (e.g. XPREG® XT135)
  • Epoxy tooling board (e.g. EB700 Epoxy Tooling Board with S120 Board Sealer)
  • Aluminium / stainless steel moulds
  • Toughened glass (for flat sheet/panels)

Although it is possible to use vinylester tools (such as Uni-Mould) they are not recommended due to the increased possibility of surface imperfections (pin holes) which can occur when XPREG® XC110 is cured in the presence of vinylester.

See XC110 Technical Data Sheet and XC110 Processing Guide for full details on mould compatibility.

Curing Oven

To cure the XC110 prepreg carbon fibre included in the kit you will require an oven capable of accurately holding the set temperature, up to 120°C. Programmable ramp rates and set points are advantageous but not essential. You will need to maintain an active vacuum connection inside the oven and so a vacuum port (or hole) through the oven wall is required.

About Prepreg Carbon Fibre

Prepreg carbon fibre components are widely regarded as the pinnacle of advanced composites; their incredible performance and stunning appearance making them the most sought-after performance parts on the market. Prepreg carbon fibre is used to make the chassis and body panels of Formula 1 cars and the wings of the latest 'Dreamliner' passenger jets.

Traditionally, working with prepreg carbon fibre has required always required an autoclave, a very expensive piece of machinery used to cure the prepreg under high pressure and temperature. With this starter kit however, Easy Composites has put together a complete package of materials specially developed to mean that anyone can make stunning prepreg carbon fibre parts with only this kit and an oven (see notes below).

Worldwide Use

The EC.4 Compact Composites Vacuum pump optionally included with the kit can be only used on 240V systems and is available with a choice of power leads for compatibility.

Kit Contents

The kit is available in two sizes; 'Regular' and 'Professional'. There is no difference in the materials used in the two kits and both kits will produce parts of exactly the same professional standard. The only difference is the quantity of the materials included. Both kits are available with or without a Composites Vacuum Pump.

Our starter kit includes a 240gsm surface layer and a 430gsm backing layer. Once vacuum bagged and cured the 240gsm will add around 0.25mm of thickness and the backing will add 0.45mm so the two layers together are 0.7mm thick. Of course, you can layer several layers of the 430gsm to increase the thickness of the laminate as required.

We recommend keeping pre-preg sealed in its bag in a freezer at -18 °C or colder. Providing it will fit in, most domestic or commercial freezers are perfectly suitable for storing prepregs.

Yes, for a successful cosmetic finish, you will need to maintain constant vacuum throughout the cure process.



We always recommend an active vacuum connection be maintained to the parts throughout the curing process, as in the case of a very tiny leak, it will sometimes not damage the finished parts. If the bag still felt tight after the drop test but a tiny change in the pump not was detectable when opening the valve then this sort of micro-leak can probably be overcome. If, however, the bag actually feels slack after the drop-test then the leak needs to be found or the whole part re-bagged.



If you intend to cure you part in the oven without an active vacuum connection to it then you MUST have a perfect seal. Any leak in the bag whatsoever, without an active vacuum connection, will guarantee a failed part.

....I'm looking to make a large moulding that won't fit in an oven. Can I still use vacuum bagged prepreg and leave for a longer cure time, or will the material not cure at room temperature? In the latter case should I use a wet layup and if so do I still vacuum? Thanks

Unfortunately, no - you cannot cure this prepreg properly without an elevated temperature. At ambient temperature the prepreg would partially cure but this should be considered more of a deterioration of the prepreg, not a proper flow and cure. At room temperature it would take many months for the prepreg to become even partially cured and during this time the resin would never flow in the same was as would in an oven. The end result would not resemble a proper laminate.

If your part is too large for an oven, it might be worth you considering our resin infusion starter kit instead. The resin infusion process will give you parts of comparable quality and performance to those made from prepreg carbon fibre without the requirement to cure the parts in an oven.
