Abstract Epoxy matrix with high modulus was synergistically designed by organic amide acid (AA) and inorganic nano silica (SiO2) as well as stiffened interphase of carbon fiber composite, and the effects of matrix modulus on longitudinal compressive strength and failure mechanism of composites were investigated. The elastic and shear modulus of matrix was enhanced by increased chemical cross-linking cites of AA and mechanical restraint of SiO2, contributing to improved interfacial properties fro...

Abstract Hydroxy-terminated waterborne polyurethane (WPU) and oxazolidone-containing epoxy (OXEP) matrix were designed to realize two-stage interface enhancement of WPU sized aramid fiber/oxazolidone-containing epoxy (WAF/OXEP) composite, and the interfacial properties and interphase reinforcing mechanism were investigated. Compared with commercial aramid fiber (CAF), the surface roughness and energy of WAF were increased, and the fracture toughness and elongation at break of OXEP matrix were im...

Abstract Objective The object is to find an easy but efficient way to illustrate the in-situ dispersion of nano-scaled one-dimensional fillers in composite resins, and to correlate their dispersion status with the properties of composite resins. Methods Fluorescent europium-doped hydroxyapatite nanowires (HANW:Eu) were synthesized via the hydrothermal method. The HANW:Eu was mixed into Bis-GMA/TEGDMA (60/40, w/w) at different contents (1–5 wt.%), and different processing methods (kneading, grind...

Abstract Amino terminated and π-conjugate naphthalenediimide (NDI) was designed and novel interphase with self-assembled NDI/multi-wall carbon nanotube (MWNT) was constructed on high-modulus carbon fiber (HMCF) surface, and the interfacial properties and reinforcing mechanisms of HMCF composites with various interphase were investigated. The nanoscale stiffening interphase with intertwined MWNT and flat ensiform nanostructure from NDI self-assembly were observed on MWNT@HMCF and NDI@HMCF surface...

Abstract According to surface chemistry and topography of different high-modulus carbon fiber (HMCF), interfacial properties of various HMCF composite were evaluated, and nanoscale wetting analysis of HMCF were studied using experimental methods and molecular dynamics simulation. Hierarchical amount of active functional groups and nanoscale grooves were detected on the surface of pristine HMCF (p-HMCF), anodic oxidized HMCF (a-HMCF) and sized HMCF (s-HMCF). Remarkable enhancements in interfacial...

Three-dimensional (3D)-printable shape-memory polymers (SMPs) are of great interest for making advanced shape-memory materials. However, it has been challenging to combine 3D-printable capability with shape-memory function into one material. Here, we report a UV-curable epoxy with excellent shape-memory performance and improved toughness as compared with traditional epoxy counterpart. The epoxy system is realized by cross-linking epoxy resin diglycidyl ether of bisphenol F (DGEBF) (“hard” segmen...

Graphene oxide/polyurethane/epoxy (GO/PU/EP) membranes were directly fabricated by functionalization of graphene oxide with epoxy-grafted polyurethane (GO-UE), and the interface correlation and crack propagation mechanisms in GO/PU/EP membranes interlaminar-toughened carbon fiber-reinforced polymer composites were investigated. The functionalized GO-UE with corrugation and scrolling nature of graphene sheets was evenly dispersed in GO/PU/EP membranes below 0.50 wt% loading. Mode I fracture tough...
