NEWS 41 CompositesWorld.com Aeris Energy, Brazil FIG. 7 Ensuring blade surface aerodynamics Wind blade finishing at Aeris includes filling, sanding and painting. Source | Aeris Energy design is, upfront, an exacting, time-intensive process that, ulti- mately, ensures that Aeris' blades meet spec with minimal waste. To start, Lolli says, when a mold is delivered, the first plies are cut to a size a little bit larger than print. ese are placed in the mold and trimmed by hand to fit the geometry of that specific mold, with no gaps or overlaps. ese plies then become the new masters for that mold and are used to program the recipe in the cutting table software. e goal, notes Lolli, is to deliver kits to each mold that are complete and precise. "Material coming into the kitting room is in a form we cannot control," he says. "When it leaves here, it must be perfect. e production hall is an assembly line, not a manufacturing line." From the cutting and kitting building, we venture outside toward Aeris' resin storage facility — a massive walled, roofed shed, vented to the outside with large, windowless openings near FIG. 8 Timely service from a talented technician Johannes Meunier, Hexion's managing director, global segment leader, wind/ composites, speaks to Aeris employees about the importance of leading-edge integrity in wind blade manufacture and operation. Hexion has been a valuable technical resource in Aeris' maturation.
