These involve advanced composite assembly processes that eliminate fastening and traditional bonding processes, as well as a lightweight corrosion resistant pipeline leak containment system.
We additionally have substantial experience in licensing intellectual property and development of suitable agreements for ease of technology implementation.
Thermoset Composite Welding (TCW™) is a patented, assembly method that eliminates fasteners and secondary bonding, and enables rapid, high-quality assembly of thermoset composite components.
The TCW™ process utilises a specially-developed thermoplastic surface layer which is integrated into the surface of the components during layup and cure. The components are then joined together in a rapid, low-cost welding process to produce a robust joint with excellent strength characteristics.
Key Benefits Compared with Conventional Technologies
Rapid assembly process with ability to automate
Significant reduction in assembly cost due to minimal surface preparation, low tooling cost, short welding time and potential to automate assembly
Equivalent or better joint strengths than adhesive bonding, as well as excellent impact and fatigue properties
Good chemical and environmental resistance
Ability to selectively disassemble and rework /repair structures
Reduction of scrap rate, resulting in reduced overall cost of assembly
COFA™ (COmposite Fitting Attachment) is a novel method to rapidly weld thermoplastic brackets and fittings to pre-manufactured thermoset composite panels, eliminating the need for fastening or traditional adhesive bonding.
The technique works via incorporation of a special thermoplastic polymer surfacing layer onto the surface of the thermoset composite laminates. The bracket can then be rapidly welded to the laminate using a rapid interface heating method, such as ultrasonic welding, which enables the joint to be made in a few seconds. The joints are strong enough for the requirements of many non-structural brackets, including those used within the aerospace industry.
The value of the COFA™ welding system lies in the following key benefits and advantages:
The rapid nature of the welding process, where joints are formed within seconds
The elimination of any requirement for drilling or fastening, or even surface preparation of the composite component
The suitability of the process for use by hand-held welders or automated systems
The simplicity of the welding process, with minimal or no surface preparation required
The possibility and ease of fitting removal and re-installation if necessary
The flexibility of the process to be adapted to various types of composite structures and brackets
