Normalization of Impact Energy by Laminate Thickness for Compression After Impact Testing

摘要: The amount of impact energy used to damage a composite laminate is critical parameter when assessing residual strength properties. compression after (CAI) impacted laminates dependent upon how thick the and this has traditionally been accounted for by normalizing (dividing) laminate's thickness. However, comparing CAI values given lay-up sequence fiber/resin system, dividing specimen thickness noted author give higher thicker laminates. A study was thus undertaken assess comparability data raised power account One set from literature two generated in were analyzed 1, 1.5, 2, 2.5 powers. Results show that as severity decreased, value which needs be order yield more comparable increases.
