Thermographic non-destructive evaluation for natural fiber-reinforced composite laminates [PDF]

open access: yes, 2018
Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize ...

Mechanical behavior of basalt fibers in a basalt-UP composite

open access: yesProcedia Structural Integrity, 2016
AbstractWith the increasing interest in sustainable solutions in material design in the last decade, research on natural materials (animal, vegetal or mineral) has increased at a rapid pace. Of these materials, Basalt Fibers for composite construction provide an interesting set of mechanical properties, equal or above to those of Glass Fibers, with ...

Synthesis of a spinifex‐textured basalt as an analog to Gusev crater basalts, Mars [PDF]

open access: yesMeteoritics & Planetary Science, 2012
Abstract– Analyses by the Mars Exploration Rover (MER), Spirit, of Martian basalts from Gusev crater show that they are chemically very different from terrestrial basalts, being characterized in particular by high Mg‐ and Fe‐contents. To provide suitable analog basalts for the International Space Analogue Rockstore (ISAR), a collection of analog rocks ...

How big is the energy efficiency resource?

open access: yesEnvironmental Research Letters, 2018
Most economic theorists assume that energy efficiency—the biggest global provider of energy services—is a limited and dwindling resource whose price- and policy-driven adoption will inevitably deplete its potential and raise its cost.
