MnO2 Nanoscale Interface Modification
<p>Interface modification of carbon fibers has been shown to improve the mechanical performance of composites. In addition, interface modification of carbon fiber composites can impart multifunctionality into the resulting composite. This work will explore ZnO and MnO2 as interface modifications …

Kinematics of Inter-Ply Interfaces In Composite Manufacturing
… a comprehensive understanding of composite interfaces and processing induced residual stresses, which critically affect both the manufacturing processes and the deformation mechanisms. Processing induced residual stresses are often responsible for causing warping, delamination, and …

Modification of a vortex-panel method to include surface effects and allow finite-element interface
… surface effects and creating a finite-element interface so that an arbitrary body can be analyzed. The basic model consists of triangular panels of linearly varying vorticity which represent the body, vortex cores on the lifting edges of the body, and vortex filaments representing the wake. The …

Synthesis and characterization of bifunctional materials for electro-optical applications
… for electro-optical applications and interfacial modifications in such applications. It is structured into two major sections each of which presenting a new concept of bifunctional materials: I. Bifunctional Ru(II) dyes carrying hole transport units II. Fully functionalized AB-diblock copolymers …

Data Intensive Method For Processing Defect Detection and Mitigation For Composites
… thermomechanical properties at the fiber-matrix interface. A novel digital image correlation (DIC)-based in situ approach was utilized to evaluate the strains and residual stresses during autoclave curing of the composites. Interface modification results in a reduced residual stress and increased …

Cohesive Zone Modelling of Fiber–Matrix Interface in Composite Materials
… is critically governed by the fiber–matrix interface which controls stress transfer and directly influences damage initiation, crack propagation, and fracture behaviour. The interface properties are quantified through the Interfacial Shear Strength (IFSS) and fracture energy, both serving as …
