The effect of low temperatures on the intermediate and high velocity impact response of CFRPs

8 pages, 13 figures.The influence of low temperature on the damage produced on CFRPs by intermediate and high velocity impacts is analyzed. Spherical projectiles were launched against different carbon fiber/epoxy laminates (tape and woven). Experimental tests were done at temperatures ranging from 25 to −150 °C. The extension of the damage was measured by C-Scan. Results show a clear dependence of damage on temperature, impact velocity and the type of the laminate.The authors are indebted to the Comisión Interministerial de Ciencia y Tecnología of Spain for financial support of this work (Project MAT98-0273). They also thank EADSCASA for assistance in C-Scan measurements.Publicad
