The effect of double impact on hygrothermally aged carbon epoxy laminates

This paper studies the effects of a repetitive occurence of impact in the same zone or point. Such occurence is unavoidable as such accidents happen and does not occur directly after the first incident but over a period of time. In order to study the effect, three stratifications of carbon epoxy f...

The effects of damage is compared to see the changes in total damage area due to the first and second impact. 2012-09 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/26652/1/Duracosys_2012_Hanan_Binte_Mokhtar_Full_Manuscript_%281%29.pdf Mokhtar , Hanan and Sicot, Olivier and Rousseau, Jerome and Aminanda, Yulfian and Aivazzadeh, Shahram (2012) The effect of double impact on hygrothermally aged carbon epoxy laminates.
