Embodiments of the invention provide a composition for shielding radiation, including 100 parts by weight of a first resin including one or more selected from the group consisting of a polyurethane resin, a polysiloxane resin, a silicone resin; a fluorine resin, an acrylic resin, and an alkyd resin; 5 to 30 parts by weight of a second resin including one or more selected from the group consisting of polyvinyl alcohol (PVA), medium-density polyethylene (MDP E), high-density polyethylene (HDPE), and low-density polyethylene (LDPE); 5 to 30 parts by weight of a polyether ether ketone (PEEK) resin powder; 5 to 80 parts by weight of a metal powder; 1 to 70 parts by weight of a metal oxide powder; 1 to 50 parts by weight of paraffin; 5 to 15 parts by weight of a boron compound; and 10 to 50 parts by weight of a carbon powder. Accordingly, a fiber complex, protective clothing, and the like including the composition for shielding radiation of the present invention includes a PEEK resin without use of lead, and thus, may shield even neutron rays as well as radiation, such as alpha rays, beta rays, proton rays, gamma rays, and X-rays.

A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.
