摘要: The main cause for failure of composite laminates is delamination under shear or transverse loading. A common approach to prevent such introduce a discrete interleaf at the midplane laminate in order increase its fracture toughness and, consequently, resistance delamination. Accordingly, study Mode I ultra-high molecular weight polyethylene fibers/polyurethane matrix interleaved with thin polyurethane films reinforced either untreated functionalized carbon nanotubes presented here. results show that—depending on surface treatment nanotubes—the introduction an generates significant improvement initiation and propagation compared non-interleaved un-reinforced films. correlate “trouser-leg” energy Copyright © 2016 John Wiley & Sons, Ltd.
