Experimental investigation on dynamic and static transverse behaviour of thin woven Carbon/Aramid hybrid laminates

open access: yesJournal of King Saud University: Engineering Sciences, 2022
Trends in the development of lightweight micro/mini Unmanned Aerial Vehicles (UAVs) demand thin composite laminates for their structural applications. As these structures experience impact loading during their life cycle, the performance enhancement in ...

Ultrasonic inspection of composites materials: Application to detect impact damage

open access: yesInternational Journal of Lightweight Materials and Manufacture, 2021
Failures detection in composite laminates is complicated respect to conventional non-destructive testings for metal structures, due to their sensibility to echoes drown in noise depending by the different properties of the constituent materials and the ...

Impacts of invasive plants on animal behaviour [PDF]

open access: yesEcology Letters, 2021
Abstract The spread of invasive species is a threat to ecosystems worldwide. However, we know relatively little about how invasive species affect the behaviour of native animals, even though behaviour plays a vital role in the biotic interactions which are key to understanding the causes and impacts of biological invasions.

IMPACT OF COVID-19 ON CONSUMER BEHAVIOUR

open access: yesRevista de Investigaciones Universidad del Quindío, 2021
A deadly virus has forced entire mankind to be confined to their homes. While many businesses were permanently shut, most others are still trying to sustain this less profit-generating period. Numerous workers are facing pay-cuts or job loss.

Impact response of balsa core sandwiches [PDF]

open access: yesFracture and Structural Integrity, 2014
The benefits of resins nano-enhanced on the impact response of sandwich composites made by fiber glass/epoxy skins and balsa wood core were studied. Afterwards, the influence of the core's discontinuity was analyzed in terms of impact strength.

Impact behaviour of nylon-rubber blends: 5. Influence of the mechanical properties of the elastomer [PDF]

open access: yes, 1989
Blends of 90wt% nylon-6 and 10wt% impact modifier were prepared. As impact modifiers were used: EPDM (ethylene propylene diene monomer) rubber, EPM (ethylene propylene monomer) rubber, polyethylene, four poly(ether esters) and some commercial impact ...

Generic behaviours in impact fragmentation [PDF]

open access: yesEPL (Europhysics Letters), 2008
We present a simple numerical model for investigating the general properties of fragmentation. By use of molecular dynamics simulations, we study the impact fragmentation of a solid disk of interacting particles with a wall. Regardless of the particular form of the interaction potential, the fragment size distribution exhibits a power law behaviour ...

Flat nose low velocity drop-weight impact response of carbon fibre composites using non-destructive damage detection techniques

open access: yesOpen Engineering, 2015
This work is mainly concerned with the nondestructive post-impact damage evaluation of carbon fibre reinforced laminated composite panels subject to low velocity drop-weight impact by flat and round nose impactors. Quasi-isotropic laminates consisting of
