- Abstract
Polymeric composites are spread applied as engineering material due to its properties sets hardly found in a single material. This specific material is, generally, constituted industrially by a combination of resin matrix (polyester or epoxy) with a structural phase such as fiberglass, carbon fiber or natural fibers. The most technologic processes utilized are the pultrusion, compressing molding and resin injection. However, in the wind turbines industry, despite the processes evolution and optimizations, a lot of work with simple techniques such as spry lay-up and hand lay-up still is required to join the huge components together. In the composites industry great developments have been done about improving composites materials properties while the production systematization did not have the same upward growth. Currently, despite the efforts, much more can be done to improve the standards of production systems. This study presents the systematic development of a composite material processed by hand lay-up to be applied in wind turbines applying Systematic Layout Planning (SLP), methods of just-in-time manufacturing, mapping and modelling processes, performance indicators, control systems and continuous improvement, interrelations and degree proximity between production steps. The work sectors design and the materials and products flow chart proposed in this work could brought about gains in reducing the production standard time (40%), practically eliminating reprocessing by contamination, and consequently reducing losses and waste (10%) with the improvements achieved in productivity and process quality.
