Abstract

To study glass/epoxy fiber orientation effects on translaminar fracture toughness under Mixed mode(I/II) load using asymmetric Four Point Bend specimen. Fracture toughness values for different fiber-oriented glass/epoxy laminates under Mixed modes are compared with unidirectional glass/epoxy laminates. Specimens were fabricated using hand layup technique with (0/45)° and (0/90)° fiber oriented glass fiber. The experimental study was conducted for 6 crack positions varying from s/d=0(Mode-II) to 1(Mode-1) with an increment of 0.2 for Four Point Bend specimen. The specimens were tested under universal testing machine to obtain peak loads and further evaluate fracture toughness. The experimental test results show fracture toughness can be increased by orienting the fiber in the laminate. Fracture toughness is highly dominating for (0/90)° fiber-oriented laminates compared to 0° and (0/45)° glass/epoxy laminates. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, the effects of fiber orientation on translaminar fracture toughness of a glass-epoxy composite laminate were evaluated using a compact tension shear (CTS) mixed mode (I/II) fracture specimen. Unidirectional (UD) glass fiber laminates of 0° and 0/90° orientation were considered for the experimental work. The fabrication of the CTS mixed mode (I/II) fracture specimen plates of thickness 9mm for various fiber orientations were done using hand lay-up technique. The CTS specimens of various fiber orientations are machined to form composite plates. The experimental study conducted for CTS specimen was of seven loading angle varying from 0° (mode-I) to 90° (mode-II) with an increment of 15° for various fiber orientation. Experimentally evaluated peak loads from CTS mixed mode (I/II) fracture specimen for various fiber orientations and loading angle are utilized to estimate the translaminar fracture toughness. The experimental results of translaminar fracture toughness of unidirectional (UD) glass fiber shows higher for 0/90° as compared with 0° fiber orientation and highly dependent on loading angle. The factography study clearly indicates that the crack initiation/direction depends on the loading angle. [ABSTRACT FROM AUTHOR]
