“…Similar results for carbon textile reinforcements bonded to an epoxy resin were reported in [4] showing an increasing trend in impact resistance with increasing specimen thickness. Note that for short and long basalt fiber reinforced thermoplastic matrix laminates the Charpy impact strength was found in the range of 48-75 kJ/m 2 [3] comparable to the values obtained for glass fabric based systems.…”

“…Numerical simulation of these tests is still at its infancy and is typically reduced to the analysis of macroscopically homogeneous orthotropic systems [4] irrespective of the actual microstructure. This is partly attributed to the geometrical complexity of the reinforcements, which is often of random nature and its proper introduction into advanced computations calls for the definition of a certain statistically equivalent periodic unit cell (SEPUC) [5].…”

“…A further hypothesis is that specimens with higher V f values will increase opportunities for energy absorption through prestress-enhanced fibre debonding. It should be noted that studies on unidirectional fibre PMCs commonly refer to failure by delamination rather than (generic) fibre debonding, reflecting the use of prepregs [14,15,17,20] as opposed to separate fibres in unidirectional EPPMCs [2] and VPPMCs [12]. For the current study, we suggest that sample (flatwise) testing geometry and resulting (shear-induced) failure effectively render both terms interchangeable for macroscopic observations.…”

“…Metals are isotropic materials that are different from NFCs in composition, microstructure and manufacturing condition [33]. These method can miss important information of test specimen behaviour and characteristic of the material during the impact event and can provide misleading information of impact strength.…”
