Mode II delamination toughness of z-pinned laminates [PDF]

, 2004
Mode II delamination toughness of z-pin reinforced composite laminates is investigated using the finite element (FE) method. The z-pin pullout process is simulated by the deformation and breakage of non-linear springs.

Atomized Oxidative Polymerization as a 3D Printing Platform for Binder‐Free, Bulk Conductive Polymer Architectures

Advanced Functional Materials, EarlyView.
Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

About the impact behavior of woven-ply carbon fiber-reinforced thermoplastic- and thermosetting-composites: A comparative study [PDF]

, 2013
This study is aimed at comparing the response of TS-based (epoxy) and TP-based (PPS or PEEK) laminates subjected to low velocity impacts. C-scan inspections showed that impact led to diamond-shaped damage resulting from different failure mechanisms ...

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Analysis of delamination growth with discontinuous solid-like shell elements

, 2011
Delamination is one of the most important failure mechanisms in laminates. Normally, it is modelled using interface elements. These elements are placed between two layers that are modelled with continuum elements. The interface elements are equipped with

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Damage and strain rate optical characterisation of standard and tufted non crimp fabric carbon composites for Meso-scale impact models [PDF]

, 2009
As global warming is a prime concern to the wellbeing of the planet, lighter planes are a requirement to reduce CO2 emissions. Light structures made of carbon epoxy composite materials are of particular interest but are sensitive to impacts such as
