Abstract
In this work, the potential of preformed thermoplastic matrix composite tapes for the manufacturing of composite pipes by filament winding assisted by in situ ultrasonic welding was evaluated. Unidirectional tapes of E-glass-reinforcedamorphous poly (ethylene terephthalate) were laid up and consolidated in a filament winding machine that was modified with a set-up enabling ultrasonic welding. The obtained composite specimens were characterized by means of morphological and dynamic mechanical analysis as well as void content evaluation, in order to correlate welding parameters to composite properties.
Highlights
The interest in continuous fiber-reinforced thermoplastic composites is continuously increasing due to their inherent benefits compared with thermoset composites such as damage tolerance, high impact resistance, chemical and solvent resistance, unlimited shelf life, low storage costs, weldability, and recyclability [1,2,3]
A recent and promising application of thermoplastic matrix composites is in pipelines, especially in the offshore industry, where high corrosion resistance, high stiffness-to-weight ratio, and low maintenance costs are crucial
Typical matrices used in the production of thermoplastic composite pipes are PolyEthylene (PE), PolyPropylene (PP), PolyAmide (PA), PolyVinylidene
Summary
The interest in continuous fiber-reinforced thermoplastic composites is continuously increasing due to their inherent benefits compared with thermoset composites such as damage tolerance, high impact resistance, chemical and solvent resistance, unlimited shelf life, low storage costs, weldability, and recyclability [1,2,3]. Other key advantages of thermoplastic composites include the potential of fast in situ out-of-autoclave processing, by applying pressure and heat in one step, and the potential for automation with significant decrease of work time and costs [4,5]. For these reasons, fiber-reinforced thermoplastic composites are continuously replacing traditional materials like metals and wood in many applications [6,7]. One of the main problem of thermoplastic composites is the high viscosity of the molten matrix, which leads to a difficult impregnation of the fiber bundle. Typical matrices used in the production of thermoplastic composite pipes are PolyEthylene (PE), PolyPropylene (PP), PolyAmide (PA), PolyVinylidene
