Abstract
Fiber-reinforced organic polymer aerogels, articles of manufacture and uses thereof are described. The reinforced aerogels include a fiber-reinforced organic polymer matrix having an at least bimodal pore size distribution with a first mode of pores having an average pore size of less than or equal to 50 nanometers (nm) and a second mode of pores having an average pore size of greater than 50 nm and a thermal conductivity of less than or equal to 30 mW/m·K at a temperature of 20° C.
