Abstract
The scratch behaviour of the Basalt/Bagasse fiber reinforced Poly (lactic acid) hybrid composite is investigated to understand how the mechanical retaliations of plastics which undergo an induced scratch deformation by a diamond tip under a constant load and linearly increasing normal load.”Aesthestics, where visible scratches reduce the products quality”. In this work scratch test were performed with constant normal loading and linearly increasing normal load conditions. An attempt has been created to gauge the scratch deformations supported visual, optical observations of failure and fracture mechanisms and morphological surface examinations through Scanning electron microscopy(SEM). Elastic deformation dominates underneath high hundreds within the total deformation. The scratch deformations dependent on the type and physical nature of the wt % of the material added. Scratch sub surface erosion damage in polymers is studied using SEM images. It is observed that the parabolic shear is a the main cause of the plastic flow, while viscoelastic nature on the surface and shear induced fracture on the surface of PBaBg I, III & IV composites are the main damage mechanisms found in the fracture scratch pattern.
