| Summary: | This research is focus on the study of impact response of advanced laminate
composite. This research investigates the effect of different velocity on impact
behavior of different types of advanced composite materials. Impact may be defined
as the relatively sudden application of an impulsive force, to a limited volume of
material or part of a structure. The effect of impacts are widely known and yet
analyzing the phenomenon and relating effects to the forces acting and the materials
properties. The specimen used in this project are uni-directional carbon fibre, woven
carbon fibre and woven glass fibre. Three type of testing were carried out including
Quasi-static compression test based on ASTM D695, surface analysis using scanning
electron micrograph (SEM) and Finite Element Analysis using Cosmos Xpress. In
this study, Quasi-static compression test were carried out at different loading rate
ranging from 0.2mm/min to 0.6mm/min for each type of material. From the results, it
is found that the mean load of woven type of carbon fibre and glass fibre process the
highest load compared to uni-directional carbon fibre. During impact test, the highest
velocities used have an effect on the structure of material. This is because load and
energy are directly proportional. As the load increase, therefore the energy increased.
Fractographic is use to study the fracture surface. This has proved to be extremely
useful for failures in fibre reinforced plastic composites. The orientations of material
have an effect on failure surface analysis of material. Several types of damages were
observed under impact test and this includes upper failure, fractured failure,
fragmentation failure and kind band failure. |
