RefiFLEX-25S carbon connectors 25x25mm

RefiFLEX-25S Universal construction system for square 25mm Carbon Tubes  

RefiFLEX-25S is a unique construction system of full carbon fibre connectors for 25 mm square carbon tubes. Gluing the carbon connection pieces with the 25 mm tubes creates a 100% carbon fibre epoxy construction, extremely low in weight, optimally stiff and strong. By using carbon connectors, heavy aluminium or plastic couplings with mechanical connections are unnecessary.

With RefiFLEX we offer engineers and constructors a simple method for making lightweight frames and constructions where rigidity is essential. 

The RefiFLEX-25S construction system includes:
  • Square Carbon Fibre Connectors 25 mm with various corner connections
  • 25 mm carbon tubes of 1150 mm or 2300 mm with a wall thickness of 1.5 mm
  • Special adhesive for an optimal connection
  • Protective equipment and auxiliary materials
  • Extensive instructions
  • Product specifications

The lightweight carbon connectors are made of premium first class prepegsbased on epoxy resins. The connector is made up of fabrics with evenly distributed fibre direction. Because of this, the strength of this product is even in all directions. The user must always judge for itself whether he/she would deem the coupling piece to be strong enough for his or her construction.
The exterior finish is made of carbon twill.

Every connector can be glued with a two-component epoxy to a carbon tube 25x25. Carbon web shop has selected a specific glue for bonding: Araldite 2031. If you are interested in Araldite, we can offer you a glue starter kit. You can find this product in the ‘Adhesives’.

It is possible to let Refitech manufacture products according to your wishes. We are also gladly be willing to help you with post-processing, such as drilling and/or CNC milling. In addition to that, the Carbon Webshopcan entirely glue or assemble your frame or construction.
For more information, we request you to contact us. 

Benefits of using these extensions are:

  • cIncrease of process speed
  • Less deflection and higher precision 
  • Higher measurement accuracy through rigid and dimensionally stable construction
  • Improved durability
  • No oxidation and/or material derogation.
As indicated earlier, these carbon square tubes have a smooth exterior finish and a rough inside. Thus, we highly recommend you that when bonding parts into a tube, always rub off folds and uneven parts. 
It is possible that the connectors only fit into the tube after sanding. We therefore advise you to use the largest possible sanding surface to prevent damage!

 

RefiFLEX


With RefiFLEX you easily assemble your own lightweight frames and systems thanks to our carbon tubes and connectors, which have been designed for easy use. In combination with glues like Araldite, which you can order on our web shop, you can construe all sorts of shapes and solutions.

 We use high-quality, first-class prepregs based on epoxy resins to manufacture our lightweight carbon connectors. The even distribution of fibre directions in our materials means you can be sure of a balanced performance. Make sure you assess and test your construction for stiffness, strength and functionality, as every application has unique properties.

Carbon square tubes have a smooth exterior finish and a rough inside. When bonding parts into the tube, always rub off folds and uneven parts. It happens that the connectors only fit into the tube after sanding. We therefore advise you to use the largest possible sanding surface and try to prevent damage.

Adhesives
The best adhesive for our connectors is 2-component epoxy glue. At Carbon Webshop, we recommend Araldite 2031.

Build your own lightweight carbon constructions


Do you want to build your own lightweight constructions? With our easy-fit round and square carbon fibre connectors, you can. Combining the connectors with our 25 mm square and 30 mm round carbon tubes offers you endless construction possibilities.
 
Advantages over conventional materials
Demand for alternative materials for building frames and systems – other than aluminium, for example – is rising. You’ll find that using carbon fibres offers many advantages over conventional materials:

 
  • Lighter
  • Higher chemical resistance
  • Better thermal insulation
  • Greater thermal stability
  • Material decomposition or oxidation
 
Advantages for your construction
The use of carbon fibre will positively impact your construction in numerous ways, for example:

 
  • Increased processing speed
  • Reduced deflection, higher precision
  • Higher measurement accuracy due to construction stiffness and dimensional stability
  • Longer lifecycle (greater durability)
  • No worries about oxidation or degradation

Our connector types and services


At the Carbon Webshop, we produce six different types of round and square carbon connectors. All these can be joined with 2-component epoxy adhesive. On request, we can also deliver various tailored compositions. We will provide whatever materials and services you need on the basis of a pre-agreed price. Our additional services include:
 
  • CNC milling
  • Bonding or full assembly of your frame or construction
 

Examples of constructions and applications realised with Refitech

  • Extractors for plastic injection moulding machines
  • Extendable carbon telescopes
  • Robot grippers for product handling
  • Push-pull rods
  • Frames and components for UAVs and drones
  • Measurement and test rigs for laboratories
