Audited Supplier Product description
The surface ply for our LK110 out-of-autoclave prepreg carbon fibre system. This is an uncured prepreg material and requires an oven or autoclave to cure it.
This 210gsm 3k prepreg uses a 2x2 twill weave for the classic carbon fibre appearance and excellent drape characteristics. It can be used on its own, in one or more plies, or together with a heavier backing ply for thicker laminates.
This prepreg reinforcement is 1.25m (1250mm) wide and sold in a choice of prepacked roll lengths.
It is an advanced out of autoclave prepreg carbon fibre surface system designed specifically for out-of-autoclave (vacuum bag, oven cure) processing. After several years in development, LK110 is a class-leading prepreg system capable of producing carbon fibre components with a 'class A' surface finish and minimal void content when oven-cured under vacuum pressure only.
Components made using the LK110 resin system offer mechanical properties comparable to autoclave-cure systems without the need for expensive autoclave plant or the associated cycle costs. The system is also ideally suited for large components which exceed the capacity of typical autoclaves, such as boat hulls and turbine blades.
LK110 prepregs can be backed-up with (and co-cured alongside) unidirectional reinforcement and are fully compatible with our XA120 adhesive film meaning that even the most complex composite structures - including honeycomb cores - can be achieved out-of-autoclave.
The OOA prepreg carbon fibre 3k 210g material listed on this page is recommended for use as a surface ply, typically backed-up with one or more layers of LK110 416g 12k Backing Ply.
Typical Uses
OOA prepreg carbon fibre surface fabrics such as this XC110 are the recommended system for both structural and cosmetic applications where components will be cured without an autoclave.
The combination of excellent mechanical performance, visual quality appearance and class-A surface finish make LK110 prepregs suitable for a wide range of applications from large-scale structural components to high-precision cosmetic parts.

Curing
It is designed to be oven cured in a vacuum bag at full vacuum pressure however it can also be cured in an autoclave or hot-press. Minimum vacuum pressure is 10mbar.
For best results, an accurately controlled multi-stage temperature cycle with final cure temperature of 120°C should be followed. See technical datasheet or LK110 Processing Guide for details, including a range of alternative cure cycles from 85°C.
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.
Fully Compatible:
Although it is possible to use vinylester tools they are not recommended due to the increased possibility of surface imperfections (pin holes) which can occur when it is cured in the presence of vinylester.
Storage and Handling
When not in use, prepregs should be kept frozen at -18°C (0°F) in sealed plastic packaging. When ready to use, the material should be removed from the freezer and allowed to thaw fully to room temperature before being removed from the packaging.
Remaining material should be re-sealed before returning to the freezer to avoid the risk of moisture uptake.

This product is not classed as dangerous goods for transport and can be shipped to all destinations without restriction.
Prepreg materials are stored in our freezers at -20°C and are shipped from our warehouse still frozen.
This prepreg has a particularly short 'out-life' and for the best performance, the amount of time it spends at room temperature should be kept to an absolute minimum.
During summer months or periods of hot weather, only order this prepreg at the start of the week (Monday or Tuesday) to avoid adding extra shipping days over the weekend. Alternatively, please contact us to discuss alternative shipping arrangements.
Unless you plan to use the product immediately, it should be placed into frozen storage as soon as possible on receipt.
We remind all international customers that it is their responsibility clear goods through their local customs. Any delay caused during customs clearance is outside of our control and as such we cannot refund or replace materials which are found to be damaged or unusable on arrival as a result of delays during customs clearance.
Whilst such delays are very rare, we strongly advise all customers intending to import prepreg materials to contact their local customs agency to seek full clarification of the import procedure and whether delays are likely before placing an order. By placing an order for prepreg materials, you accept these conditions of sale.
When packaged, this product is over 1m in length. A small additional handling charge will apply when shipping to some countries and regions. When applicable, this handling charge will be included in the automatic shipping calculation shown on the basket page.
