摘要：

A multifunctional non-destructive technique, based on the Raman response of aramid fibers, is employed for (a) assessing the interface integrity and the overall stress distribution in a unidirectional Kevlar 29(R)/epoxy composite (b) measuring the stress concentration and its development with applied load in Kevlar 49(R)/epoxy composites incorporating a circular notch and finally, (c) determining the strain arising in 0degrees plies due to partial and full crack growth within the thetadegrees plies in multidirectional 0degrees/thetadegrees/0degrees composites. It is shown that this technique can be used effectively to study the damage development in composite materials that arise from the presence of different length scale discontinuities.
