The wind energy market has long been considered the world’s largest market, by volume, for glass fiber-reinforced polymer (GFRP) composites — and increasingly, carbon fiber composites — as larger turbines and longer wind blades are developed, requiring higher performance, lighter weight materials. The outer skins of wind and tidal turbine blades generally comprise infused, GFRP laminates sandwiching foam core. Inside the blade, rib-like shear webs bonded to spar caps reinforce the structure. Spar caps are often made from GFRP or, as blade lengths lengthen, pultruded carbon fiber for additional strength.
CW was at the scene when the composites-intensive Si2 landed in Phoenix, AZ.
JEC World 2025: KraussMaffei presents innovations for lightweight composite construction and surface technologies, from HP-RTM, LFI and ColorForm to the printCore extruder.
The expansion includes an Industry 4.0 factory to automate and digitalize the production of solar arrays for satellites, as well as expanded clean rooms for optical satellite instruments.
Celebrating National Composites Week 2024, CW looks at how composites are being used to provide the next generation of energy.
Exel adapted carbon fiber profiles originally designed for wind turbines to meet the low-drag, high-flexibility and long-term fatigue performance demands of this renewable energy system’s nature-inspired membrane.
Rock West Composites’ chief strategy officer discusses recent surge in space applications on the CAMX 2024 show floor.
Bye Aerospace completes first flight of the solar electric technology demonstrator prototype for its StratoAirNet and Solesa families of medium-altitude aircraft systems.
SolAero Technologies Corp. has successfully completed ground testing of the integrated solar wings on Bye Aerospace's medium-altitude, long-endurance solar-electric unmanned aerial vehicle (UAV), called StratoAirNet.
Pilots André Borschberg and Bertrand Piccard successfully complete the first leg of what is intended to be a five month global aerial circumnavigation.
The company’s goal of perpetual solar flight would allow them use UAVs to enable internet access to parts of the world that have no access.
