Abstract: Fiber-reinforced terephthalate-co-4,4′-bibenzoate copolyester behaves like a liquid crystalline polymer, providing fast crystallization, short cycling times, high Tg and Tm, high strength and stiffness, while the viscosity is unexpectedly reduced at a low fiber loading ratio. In an injection molding process, the viscosity of the fiber reinforced copolyester at low fiber loading is reduced by increasing the fiber loading.

Abstract: The present disclosure provides an aerogel formed of a tannin-containing porous material including a polymeric material, a tannin, and a clay. In some embodiments, the tannin-containing porous material is produced by forming an aerogel precursor including a polymeric material, a tannin, and a liquid dispersion medium; freezing the aerogel precursor; and freeze drying. In other embodiments, the tannin-containing porous material is produced by coating a formed porous aerogel material with a tannin-containing coating solution including tannin dispersed therein. The aerogel provides a flame retardant material having improved mechanical properties.
