THERMOPLASTIC PUR WITH HIGH TG FOR REACTION TRANSFER MOLDING (RTM)

The invention relates to a thermoplastic polyurethane matrix resin composition, comprising (i) at least one bridged and/or fused and/or Spiro polycyclic alcohol compound; (ii) at least one polyisocyanate; and (iii) at least one diol, which is different from the at least one bridged and/or fused and/or spiro polycyclic alcohol compound (i). The at least one bridged and/or fused and/or Spiro polycyclic alcohol compound (i) is present in the thermoplastic polyurethane matrix resin composition in an amount of at least 10 wt.-% by weight, preferably at least 20 wt-%, most preferably at least 25 wt.-%. Furthermore, the present invention relates to a fiber-reinforced composite comprising a cured thermoplastic polyurethane polymer matrix according to the present invention and a fiber material. Moreover, a method for the manufacture of the fiber-reinforced composite according to the present invention and use of the composition or the fiber-reinforced composite in railway vehicles, automotive vehicles, aircraft vehicles, boats, space vehicles, motorbikes, bicycles, sporting goods, e.g., skis, snowboards, rackets, golf clubs, fishing rods, baseball bats, hockey sticks, arrows, archery bows, surfboards, javelins, exercise equipment, cell phone and laptop housings, helmets, functional clothing, shoes, construction parts in bridges and buildings or wind turbine blades are described.
