Popis: Development of environment-friendly products with woven sisal/epoxy polymer composites necessitates joining operation. The design of the overlap joint plays a significant role in defining the performance of the adhesively bonded composite parts. In the current experimental investigation, the effect of drilled holes (in overlap area) on the load-carrying capacity of single-lap adhesively joined sisal-epoxy polymer composites has been studied. Four different hole arrangements have been compared. The holes were drilled in the adherends using a twist drill of 2 mm diameter. The mechanical properties of sisal-epoxy composite laminate were found to be better than the pure epoxy specimen. The specimens to be used as adherends were cut from a fabricated composite laminate as per ASTM D5868-01. The maximum shear strength and failure load were recorded for four- and eight-hole arrangements. The field emission scanning electron microscopy (FE-SEM) images of the fractured surface of sisal/epoxy composites after tensile testing reveal that relatively fewer fiber breakouts and de-bonding occurred indicating toward a strong adhesion between matrix and fiber reinforcement.
