WebAdding fibers will increase the creep resistance. Carbon fiber filled PEEK will still not outperform unfilled PAI at 150°C in terms of creep resistance. For example, PEEK with 30% carbon fiber shows at 100°C a better creep performance as unfilled PAI. At 150°C, this turns around and PAI has the better creep resistance.
