heal.abstract	The use of composite materials in the construction of various structural components of the car body has gained an increasing interest in the automotive industry. In relation to this, the crashworthy ability of an automotive frame rail of hour glass cross-section, made of a glass fiber/ vinylester composite and designed for use in the apron construction of the car, when subjected to axial collapse and bending, has been extensively investigated in this paper. An important problem arose, dealing with the delamination observed at the corners and curved parts of the hourglass section which may be attributed to the manufacturing processing, resulting in severe limitations in the load-carrying capacity of this structural component. The effect of the residual stress and strain fields induced during fabrication was examined both theoretically and experimentally and possible failure mechanisms observed were investigated and discussed. © 1995.	en
