This work is devoted to the experimental study of a glass/polyester composite laminate under impact shock. Based on a thermodynamic approach, the objective is the evaluation of specific interlaminar delamination energy in a multi-layer composite material under impact loading causing damage to it by cracking. | Experimental study of a woven fiberglass composite delamination under impact shock Engineering Solid Mechanics 2 2014 163-172 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Experimental study of a woven fiberglass composite delamination under impact shock .

Based on a thermodynamic approach the objective is the evaluation of specific Received in Revised form interlaminar delamination energy in a multi-layer composite material under impact loading April 10 2014 causing damage to it by cracking. For modeling impact loading it is used an experimental Accepted 7 May 2014 Available online device based on the principle of Charpy test which is to measure residual energy of a mass 9 May 2014 movement following a shock at speeds generally between 1 and 4 m s on a test piece cut of Keywords standardized dimensions requested in bending. Some of available energy is consumed by the Interlaminar delamination rupture of the test piece. The results of this work showed that for impact test mode I fracture Specific delamination energy energy is function of impact speed and the load fall energy. These results could be useful in the Charpy test design of multilayer structures in composite materials subjected to impact loads. 2014 Growing Science Ltd. All rights reserved. 1.
