THE CORRELATION BETWEEN STRENGTH CHARACTERISTICS, POROSITY AND ULTRASONIC TESTING DATA FOR FRP SPECIMENS MADE WITH AUTOCLAVE AND INFUSION TECHNOLOGIES
(pp. 40-51)

Abstract. The strength characteristics of fiber reinforced plastics (FRP) as compressive and shear strength are depends on material micro defects (for example porosity) existence. The research results of correlation communication between ultrasonic testing data, strength characteristics and porosity contents at FRP specimens made with autoclave and infusion (RTM) technologies are present at this work. Two types of CFRP were researched: the first type based on ELUR-P carbon fabric and VK-36R adhesive made with autoclave technology, the thickness was 5,5 and 8,5 mm, the second type based on ELUR-P unidirectional carbon tape and VSE-21 binding made with infusion technology, the thickness was 3,0 and 5,3 mm. Correlation dependencies between porosity, compressive and shear strength, low-cyclic fatigue and back wall echo amplitude decrease for CFRP specimens are presented and analyzed. These dependencies may be used for definition of porosity influence to CFRP ELUR-P/VK-36R and ELUR-P/VSE-21 strength properties and for choosing of the rejection criteria based on strength decreasing during ultrasonic testing.

Keywords: FRP, CFRP, porosity, void, ultrasonic testing, ultrasonic fluctuation, strength, compressive strength, interlaminar shear strength, low-cycle fatigue (LCF).
