FRP Bonding Angles complimenting the DuFLEX and Featherlight Composite Panel Systems

27th February, 2018


Composite 90o Bonding Angles manufactured by ATL Composites have been designed to provide a quick and effective means for making right angle joints between DuFLEX and Featherlight Composite Panels. These pre-cured angles can be bonded in place with an epoxy paste adhesive, speeding up assembly and reducing wet lay-up.  They are also ideal for inaccessible areas where wet fibreglass taping would be difficult.

• Lighter and More Consistent than Wet Lay-Up
• Faster to Install, especially Over-Head
• Extremely High Strength to Weight Ratio
• Can be Kerffed and Curved for Partition Bases

Bonding angles are faster and easier to install than standard taped joints and ideal for inaccessible areas where fibreglass taping would be difficult.

Bonding Angles consist of multi-axial E-Fibreglass in a high performance epoxy matrix, peel plied on all surfaces, with the fibre direction tailored for optimum load carrying capability and stiffness. The automated construction process ensures a consistently superior fibre content and high quality finish. This combination of resin matrix, fibre content and orientation assures optimum mechanical properties while the use of an epoxy adhesive enhances the bond strength.  

Composite Bonding Angles are lighter than equivalent aluminium, steel or timber sections with superior resistance to corrosion and fatigue, and no wet lay-up is required, they are simply installed with appropriate surface preparation and an epoxy adhesive.

ATL Composites specify the following high density epoxy adhesive for use with our FRP Bonding Angles:

• WEST SYSTEM® epoxy resin/hardener thickened with 413 Microfibre Blend
• Techniglue® Adhesives

FRP Bonding Angles are available in 42mm and 84mm leg lengths and are supplied in 2400mm Lengths.

Typical applications include:  
Marine - deck, hull, bulkhead and flooring attachments;  Road transportation – truck beds, bodies, side walls and bus floor supports;
Industrial Applications – floors, walls, roofs and cabinetry.

 

 

 

 

 

In both circumstances, failure of the joins was through the adhesive rather than the Bonding Angle.
