Geometric and scale effects on energy absorption of structural composites [PDF]

open access: yes, 2011
PhDThe challenge faced by structural designers is becoming increasingly difficult as the imposed design criteria of energy absorbing structures requires weight reduction of structures without compromising cost and crushing performance.

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation. [PDF]

open access: yesAdv Mater
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Fracture Behaviors of CFRP Laminates in Mode I Interlaminar Fracture Toughness Testing.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1997
Fracture behaviours in mode I delamination tests of CFRP(T300/2500)were studied at cross-head velocity V=0.005∼200 mm/min. In low velocity region, serrations due to repeated unstable fracture appear on load P-displacement δ curve, and they become conspicuous as V becomes smaller.

The influence of hydrostatic pressure on the interlaminar fracture toughness of carbon/epoxy composites [PDF]

open access: yes, 2006
The use of composites for deep sea applications requires a thorough understanding of the behaviour of these materials. While several studies have examined the influence of pressure on in-plane properties few data are available for the interlaminar ...

Finite element analyses of mode I interlaminar delamination in z-fibre reinforced composite laminates. [PDF]

open access: yes, 2003
This paper presents a detailed numerical study of the mode I interlaminar fracture of carbon/epoxy composite laminates with z-fibre reinforcement. The study was performed using a double cantilever beam configuration.

Finite element modelling of mode I delamination specimens by means of implicit and explicit solvers [PDF]

open access: yes, 2012
The simulation of delamination using the Finite Element Method (FEM) is a useful tool to analyse fracture mechanics. In this paper, simulations are performed by means of two different fracture mechanics models: Two Step Extension (TSEM) and Cohesive Zone

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

open access: yes, 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
