An effective approach has been developed for the catalytic decomposition of acetylene (C2H2) by chemical vapor deposition (CVD), to achieve homogeneous growth carbon nanotubes (CNTs) on surfaces fibers. The morphology CNTs grown fiber was observed a scanning electron microscope and high-resolution transmission microscope, which revealed uniform coverage surfaces. single tensile test demonstrated that strength fibers could be increased more than 12% with their surface. reparation damage...
Controllable growth of CNTs/CNFs on carbon fiber surface without degradation tensile strength fibers.
Two kinds of carbon nanoproducts with different microstructures, namely, nanotubes (CNTs) and nanofibers (CNFs), were grown on the surface fibers (CFs) by chemical vapor deposition (CVD) at low temperatures to improve interface bonding between resins. The short-beam method micro-debonding used test interlaminar shear strength (ILSS) interfacial (IFSS) composites. results showed that contribution CNTs improvement properties was better than CNFs. Specifically, ILSS IFSS CF-CNFs/epoxy...
Abstract Carbon nanotubes (CNTs) were continuously grown on the surface of moving carbon fiber by chemical vapor deposition method using a custom-designed production line to prepare composite reinforcements large-scale. The systematic study different parameters affecting CNT growth revealed simple kinetics, which helps control morphology and structural quality CNTs. Since hydrogen maintains activity catalyst, it promotes CNTs in continuous process. increase acetylene partial pressure...
Abstract This study aimed to improve the flexibility of E-51 epoxy resin by using polyamide/polyether amine as a two-component curing agent. Through solid state nuclear magnetic resonance (SSNMR), it was found that cross-linking density could be effectively reduced adding polyamide and polyether The tensile tests showed elongation-at-break remarkably improved. It differential scanning calorimetry (DSC) behavior system varied with addition different amine. Phase contrast microscope phase...
Carbon nanotubes (CNTs) were grown on the surface of carbon fiber fabrics by a novel chemical vapor deposition (CVD) with Co and Ni catalyst precursors loaded their surfaces impregnation respectively. The method is carried out at 600°C keeping pressure quasi-vacuum. It was found that when used as CVD time 5 min, yield CNTs moderate, degree graphitization high tensile strength has maximum value. effect parameters morphology properties CNTs-grafted been revealed, which can serve fundamental...
This article aimed at development of a catalyst for the highly efficient preparation carbon nanotube (CNT)-grafted fibers (CFs) with high mechanical properties by using chemical vapor deposition (CVD). Based on an innovative technique uniform coating CF surface, influence type morphology and CNT-grafted CFs has been systematically studied. It was found that trace addition Cu can significantly enhance catalytic activity Fe catalyst, corresponding tensile strength final is 12.0% higher than...
Most of the methods for growing carbon nanotubes (CNTs) on surface fibers are usually a laboratory scale and cannot be applied to industrial production large scale. Here, novel technique has been successfully developed grow CNTs continuous moving fiber surfaces by unique open-ended chemical vapor deposition (CVD) furnace. The experimental results show that achieve uniform growth fibers, repairing defects improving tensile strength. This study provides an original vision CNTs, it will...
We investigated the influence of bimetallic catalysts with various compositions on growth carbon nanotubes (CNTs) surface continuous fibers (CFs). The samples were analyzed and characterized by scanning electron microscopy, transmission Raman spectrometry. catalyst plays an essential role in catalytic chemical vapor deposition CNT. performance these was estimated referenced to both CNT morphologies, while influences each components summarized according results. This work prepared studied six...
