Item type:Publication, Access status: without files , Protective effect of thin alumina layer on carbon fibre to preserve tensile strength during CNT growth by CVD(2014-06); ; ; As received AS4 carbon fibres were covered with a thin alumina layer by atomic layer deposition prior to the growth of radially aligned carbon nano tubes onto the fibre surface. The deposition of alumina was found to preserve the initial fibre tensile strength in the harsh conditions during carbon nanotube growth by chemical vapour deposition. The fibre tensile strength was measured by single fibre tensile test for fibres treated with different processing parameters. The interphase properties between carbon fibre, alumina layer and matrix material were characterized by carrying out single fibre fragmentation tests. The length of the ongrown carbon nano tubes can exceed 7 μm, i.e. the carbon fibre diameter. Experiments prove that the deposited alumina layer with a thickness of as little as 12.8 nm preserves the fibres initial tensile strength.Publicationtype: Conference Paper11 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Inverstigation on the failure mechanism of composite fasteners with countersunk head in fatigue loading(2014-06); ; ; ; This experimental study presents a detailed study on the failure mechanisms of a CFRP single-lap shear joint under cyclic loading conditions. The joint consists of two laminate plates and two CFRP fasteners with countersunk heads. Based on the investigations of this experimental work, the failure mechanisms in cyclic loading of the CFRP-fastener can be described. Further test with different parameter configurations show their influence on the failure process of the joint.Publicationtype: Conference Paper21 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Damage mechanisms of nanoparticle-modified CFRP under very high cycle fatigue-loading(2014-06); ; ; ; In this work the influence of different types of carbon nanoparticles like multi-walled carbon nanotubes and few layered graphene on the damage mechanisms of CFRP under HCF and VHCF-fatigue loading are investigated. An improvement of fatigue life and change in dominating damage mechanism due to the nanoparticle modification were revealed.Publicationtype: Conference Paper14 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Influence of impact damages on the fatigue behaviour of composites(2014-06); ; ; Defects in composite structures, such as impact damages have a major influence on the fatigue behaviour. Based on the conducted experiments the influence of impact damages on fatigue life of glass fibre based NCF composites was characterised.Publicationtype: Conference Paper7
