COMPARATIVE ANALYSIS OF TESTING FOR POROSITY OF THE CARBON FIBER REINFORCED RESIN MATRIX COMPOSITES

Abstract

Abstract: The pores of the carbon-fiber reinforced polymer composite are formed during preparation. They have crucial influence on mechanical performance of the carbon-fiber reinforced polymer composite. Hence, it is necessary to be calibrated for the porosity. This paper studied the carbon fiber reinforced bismaleide composites. The composites laminations are cured by autoclave or microwave. They are tested by four methods, the density and metallographic method, supersonic scanning and high-precision X-ray micro computed tomography (CT). And the porosity′s content was calculated. The experimental results showed that the porosity calculated by metallographic and micro-CT is close. And the porosity by the density method has large deviation.

Key words: carbon fiber, porosity, metallographic method, ultrasonic testing, high precision X-ray digital imaging
