Wind Blade Composite Design, Manufacturing and Experimental Testing
Zusammenfassung
The design and manufacture of
composite material sandwich type blade is
presented. Stainless steel rods and ribs, are the
internal structure, core is foam, between ribs. The
skin is a laminate of fiber glass and a matrix of
epoxy, with a laminae staking sequence of -45°, 45°
and 90 °, 0 ° up to six layers.
Three point bending test, shows that the blade
can withstand approximately 200 lb, impact results
showed that the blade is damaged with energy
33.849 J, resulting in delamination and cracking
of the fiber and crazing of the matrix. Cantilevered
results showed that the blade can support only 8 lb.
A new design of the blade support is presented to
avoid critical damage.
