Speech Title: Investigation on laminated polymer composite reinforced with unidirectional carbon fiber prepreg.

Abstract: Damage characteristics of polymer composite layer reinforced with unidirectional carbon prepreg tape is analysed under different tensile loading conditions. Modelling and simulation are performed using ABAQUS (standard) software. One end of the specimen is fixed and the other end is free where tensile loads are applied. The displacement profile is presented in Fig. 1 and the load -displacement plot is shown in Fig.2. It is evident from the load-deformation plot that at the initial part, relationship is linear. The stress at different zones are different and is an expected one for typical nature of such fibrous composites. Experimental verification (Fig. 3) is under process (for COVID 19 issue) and expected to be presented in full paper.
