High Performance Composites

ATSP Innovations has developed Aromatic ThermoSetting coPolyesters (ATSP) as a very promising matrix phase for high performance composites. Given very recent advances, the synthetic development of ATSP was a major innovation in the field of polymer science. ATSP exhibits a glass transition temperature as high as 285 °C and has a service temperature up to 350 °C and 425 °C in air and nitrogen, respectively. The liquid crystalline nature of the polymer results in an intrinsic resistance to microcracking by local matching of the CTE between fiber and matrix yielding minimal residual stress in composites, especially in the fiber/matrix interface region, which also yields a higher fracture toughness and reduced dimensional changes relative to state-of-art composites. ATSP displays a unique feature among high temperature thermosets, known as interchain transesterification (ITR) which allows solid-state bonding between fully cured lamina (see below). Last but not least, ATSP has an extraordinarily broad range of chemical tailorability with impact on key metrics necessary for the proposed application.
