Pittsburgh, Pennsylvania - Bayer MaterialScience has developed a range of stronger composite materials to meet the demand of the wind power industry.
A Bayer scientist and a researcher from Molded Fiber Glass conducted studies to compare the performance characteristics of the newly introduced Baydur resin infusion polyurethane systems versus those of epoxy- and vinyl ester-based composites, Bayer said in a 17 Oct news release
The results of these studies will be presented at the annual SAMPE Tech 2011 conference and exhibition, taking place 17-20 Oct in Fort Worth, Texas, Bayer said.
A technical paper, "Polyurethane Composites for Wind Turbine Blades," by Dr Usama Younes, principal scientist with Bayer MaterialScience and Frank Bradish, a researcher with Molder Fiber Glass Research Co., will also be made available.
According to Bayer, the results of the research show that the new polyurethane-based composite systems outperformed the epoxy and vinyl ester samples in tensile fatigue, interlaminar fracture toughness testing and fatigue crack growth testing.
"These urethane systems showed much improved fatigue and fracture toughness properties as well as faster demould than resins currently used in wind turbine blade manufacture," the report said.
