Large composite structures, when manufactured with high-performing thermoplastic materials, can offer significant weight savings and environmental resistances when compared to alternative materials such as metals. Building on this, thermoplastic composites can be used to create structures reinforced with composite stiffeners. This heightens the advantages of composites allowing for even lighter designs while also broadening the range of possible geometries. A great example is the composite tail boom (pictured above) detailed in Composites World.
The Thermoplastic Advantage
Compared with traditional metal materials, neat (unreinforced) plastics, and even thermoset composites, fiber-reinforced thermoplastic composites:
As an additive manufacturing process, AFP of thermoplastic composites trims significant time and expense during manufacturing. Thermoplastics are recyclable and repairable, which cuts down on waste, and their ability to bond to differing materials enables the creation of hybrid structures.
The inherent benefits of thermoplastics lend themselves well to composite stiffeners. They are ideal for a wide variety of shapes and sizes as AFP can be used to create complex structures beyond just flat surfaces or tubes. Specifically, thermoplastic composites can be molded into an assortment of stiffener shapes including I, C, and hat stiffeners (see images).
