DETERMINING BOND STRENGTH IN FIBRE-REINFORCED COMPOSITES

A PULL-OUT TECHNIQUE SUITABLE FOR DETERMINING THE INTERFACIAL BOND STRENGTH FOR VARIOUS COMBINATIONS OF FIBERS AND MATRIX IS DESCRIBED. IN THIS METHOD A THICK FIBER, 0.5 TO 1.0 MM. IN DIAMETER, IS EMBEDDED PERPENDICULARLY THROUGH A MATRIX MATERIAL CONTAINED IN A SPECIAL MOLD AND IS STRESSED ON A TENSILE TESTING MACHINE. THE VALUE OF THE MAXIMUM BOND LOAD CORRESPONDS TO A SHARP BREAK IN THE LOAD- EXTENSION CURVE. RESULTS SHOW THAT THE BOND STRENGTH BETWEEN E-GLASS-FIBER AND CEMENT IS OF THE SAME ORDER AS THAT BETWEEN STEEL AND CEMENT BUT HIGHER THAN THE VALUES REPORTED FOR ASBESTOS AND CEMENT. THE WORK HAS ALSO SHOWN THAT THE STRENGTH OF THE BOND BETWEEN E-GLASS-FIBER AND GYPSUM PLASTER IS OF SIMILAR MAGNITUDE, BUT THAT IT IS AFFECTED SIGNIFICANTLY BY VARIATIONS IN WATER/PLASTER RATIO. /AUTHOR/
