This paper focuses on the study of the effect of rectification by grinding on the mechanical behavior in quasi-static tests (compression and inter-laminar shear) of two long fiber composite materials machined by two cutting processes: tool machining (edge cutting) and abrasive diamond cutting (ADS). Two sets of specimens of different surface roughness are generated by varying the cutting conditions for each material. One set is rectified. First, the results of compression and inter laminar shear tests show that the mechanical behavior is highly affected by the surface roughness. Secondly it is shown that the operation of rectification improves the mechanical behavior. However this improvement is highly affected by the surface roughness of the specimen before rectification and is dependent on the long fiber composite material.

Abstract

This paper focuses on the study of the effect of rectification by grinding on the mechanical behavior in quasi-static tests (compression and inter-laminar shear) of two long fiber composite materials machined by two cutting processes: tool machining (edge cutting) and abrasive diamond cutting (ADS). Two sets of specimens of different surface roughness are generated by varying the cutting conditions for each material. One set is rectified. First, the results of compression and inter laminar shear tests show that the mechanical behavior is highly affected by the surface roughness. Secondly it is shown that the operation of rectification improves the mechanical behavior. However this improvement is highly affected by the surface roughness of the specimen before rectification and is dependent on the long fiber composite material.
