The 12th Global Conference on Polymer and Composite Materials (PCM 2025)

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 is different and is an expected one for typical nature of such fibrous composites. This is a part of a bigger project with experimental investigation (Fig. 3) and is expected in full paper for possible publication.

Keywords: Carbon-prepreg-tape, epoxy resin, Unidirectional fiber, fixed-free, numerical-experimental.
