- CompositePatch enables to perform structural repairs with guarantee of quality by non composite specialist workers thanks to its error-proof system.
- CompositePatch may be used in all climate conditions: tropical countries, sub zero conditions, under the rain or even underwater.
- CompositePatch is nearly as easy-to-use as a sticker: once mixed, it may be cut and repositioned as necessary before it hardens – like a pre-preg.
- You can draw with a permanent marker on the pouch the exact size needed and then cut on the lines once the fiber is wetted.
- 4 hours after its application it will obtain 90% of its mechanical properties at room temperature (23ºC). If 60ºC curing blankets are uses, the patch cures in 90 minutes.
- CompositePatch is the lightest repair system and does not create waste: no scales, mixing pots, rollers, brushes etc. It travels easily and may form part of any service toolbox.
Regular delivery time is 10 working days, if your order is very urgent, please let us know writing at info@compositepatch.com and we would do our best to send the patch as soon as possible.
- Cosmetic repairs do not need the use the of adhesive, applying the patch on the area to be repaired is sufficient.
- When performing a repair under the rain or even underwater it is then necessary to use the adhesive as base layer on the patch to remove the film of water between the patch and the substract.
- On structural repairs, applying a layer of adhesive improves the cohesion of the repair to the cured composite like when using a pre-preg adhesive film as 1st layer when performing a repair with pre-preg.
- When delaminations on the trailing edge need repair, drilling 10 mm hole every 10 to 15 cm enable the adhesive to to fill the delaminated area due to its low viscosity and high thixotropy.
- Because CompositePatch contains the exact quantity of resin and hardener in the pouch, eliminating the risk of mixing error.
- It enables the repair quality consistency: workers ALWAYS use the same amount of resin, so the fiber/resin ratio is always the same unlike when decided by the worker himself.
- Because using composite patch eliminates the need for carrying resin and hardener pails, scales, mixing pots, acetone, brushes and rollers to carry on a repair – and it reduces the waste material.
- Being totally enclosed, it also reduces to minimum the risk of contact with the workers skin with the resin, improving H&S working conditions.
- As the fiber layers you add are protected by a plastic film, the laminate is protected from the humidity or rain until the next layer is added.
- Because repairs are done much faster than when using conventional resins & fibers: The preparation is faster, the curing time is reduced at least by half, reducing downtimes.
- Crews can simply repair more pieces per day. Estimations show 25 to 35% repair cost reductions – and the window of repair is not dictated anymore by the weather conditions, increasing dramatically the repair season length.
Yes, all CompositePatch references can be use underwater.
Higher temperature will make CompositePatch system harden faster. Please check technical data sheet available to know relation between temperature and gel time
CompositePatch range is divided between Glass Fiber and Carbon fiber references. Glass references code start with G and Carbon references codes start with C. The number that follow increases with the gramage (grams per square meter).
Glass fiber range CompositePatch and Carbon fiber range CompositePatch main difference is the mechanical properties – as a general rule, you get twice the tensile strength for a same gr/m2 reinforcement if you use Carbon fiber compared to Glass fiber. For impact/puncture though, the Glass fiber will resist more than Carbon fiber.
Please check the technical data sheet available online to know the properties for each reference.
First you need to choose between Glass fiber and Carbon fiber: if the weight issue is critical, choose Carbon fiber.Second, you need to choose the fiber type according to the type of geometrical structure you are prone to repair:
- For flat surfaces: choose the Quadriaxial type: fibers orientation is equilibrated with 4 layers of fiber oriented at +45º/-45%/0º/90º. Like this the strength of the patch is equal in all directions.
- For complex shapes: Choose the Biaxial fiber. There are two layers of fiber, oriented at +45º/-45º and this enables the patch to easily follow complex shapes.
- For straight shapes, choose the Unidirectional fiber that is oriented all in the length direction (or 0º), all the strength of the fiber will work in one only direction (for masts, repairs, booms, beams, chassis frames…etc..)
If you are not sure of the type of shape you may need to repair, choose the Biaxial type as standard patch.
