Abstract:
A boom section includes a first, a second, a third, and a fourth fiber reinforced thermoset composite material layer and a flex core layer. The first fiber reinforced thermoset composite material layer has glass fibers in a vinyl ester matrix. The second fiber reinforced thermoset composite material layer is disposed over the first composite material layer and has carbon fibers in an epoxy matrix. The flex core layer is disposed over the second composite material layer. The third fiber reinforced thermoset composite material layer is disposed over the flex core layer and has aramid fibers in a vinyl ester matrix. The fourth fiber reinforced thermoset composite material layer is disposed over the third composite material layer and has glass fibers in a vinyl ester matrix.
