Enhancement of the Interlaminar Fracture Toughness of a Carbon-Fiber-Reinforced Polymer Using Interleaved Carbon Nanotube Buckypaper

نویسندگان

چکیده

In this study, a carbon nanotube (CNT) buckypaper was interleaved in carbon-fiber-reinforced polymer (CFRP) composite to improve the interlaminar fracture toughness. Interleaving film of laminate-type poses risk deteriorating in-plane mechanical properties. Therefore, shear modulus and strength were measured prior estimating To evaluate effect on toughness CFRP, double cantilever beam (DCB) end notch flexure (ENF) tests conducted for mode I II delamination, respectively. No significant change observed due interleaving decreased by 4%. However, CFRP increased significantly. Moreover, 45.9%. Optical micrographs cross-section CFRPs obtained compare microstructures specimens with without interleaving. The surfaces after DCB ENF examined using scanning electron microscope identify toughening mechanism buckypaper-interleaved CFRP.

Predicting Young’s Modulus of Aggregated Carbon Nanotube Reinforced Polymer

Prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. A proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. The main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...

Thermal Properties of Hybrid Carbon Nanotube/Carbon Fiber Polymer Composites

Carbon fiber reinforced polymer (CFRP) composites possess many advantages for aircraft structures over conventional aluminum alloys: light weight, higher strengthand stiffness-to-weight ratio, and low life-cycle maintenance costs. However, the relatively low thermal and electrical conductivities of CFRP composites are deficient in providing structural safety under certain operational conditions...
