One of the high-performance thermoplastics that AIP works with is NYLON : a PA, or polyamide. Thermoplastic composites offer two major advantages for some manufacturing applications: The first is that many thermoplastic composites have an increased impact resistance to comparable thermosets. Thermosets provide an alternative process when complex and geometric shapes cannot be achieved through metal fabrication or the use of thermoplastics but can be manufactured in a mold. While this is true to some degree, thermosets offer more benefits than their thermoplastic counterpart.

The cross-section of the rod is critical to performance, with non-circular cross-sections being preferred over circular cross-sections. Specifications for Sheet, Tube and Rod, to meet military requirements. On the other hand, unlike the traditional flexible chain thermosets, for which lower modulus are usually associated with increase in coefficient of thermal expansion (CTE), in the case of rod-like thermoset system, CTE (50*10-6/0C) does not increase compared to traditional high modulus thermoset materials.
