Abstract
Hybrid composites are considered materials of great potential for engineering applications. One advantage of hybrid composite materials for the designer is that the properties of a composite can be controlled to a considerable extent by the choice of fibers and matrix and by adjusting the orientation of the fiber. The scope for this tailoring of the properties of the material is much greater, however, when different kinds of fiber orientations are incorporated in the same resin matrix. For the study of potential of these materials, in this work specimens were prepared with different angle ply ori entation of carbon/glass hybrid with epoxy resin as an adhesive. Three orientations viz 0°/90°, 45°/45° and 30°/60° were considered for studies. Mechanical properties such as tensile strength, tensile modulus, & peak load of the hybrid com posites were determined as per ASTM standards. Vacuum bagging technique was adopted for the fabrication of hybrid specimens. It was observed that angle ply orientation at 0°/90° showed significant increase in tensile properties as compared to other orientation. Scanning electron micrographs of fractured surfaces were used for a qualitative evaluation of interfacial properties of woven carbon-glass hybrid composites. These results indicated that carbon-glass hybrid composites offered the merits of synthetic fibers.
Highlights
A composite is a structural material that consists of two or more combined constituents that are combined at a macroscopic level and are not soluble in each other
Experiments were conducted on Glass fiber/Carbon fiber/Epoxy resin hybrid angle ply laminates with different fiber orientation to characterize the tensile properties
5) During specimen preparation angle ply hybrid composite for 0 ̊/90 ̊ orientation, glass fiber is placed in 90 ̊ and carbon fiber placed in 0 ̊, because the glass fiber is more ductile than carbon fiber
Summary
A composite is a structural material that consists of two or more combined constituents that are combined at a macroscopic level and are not soluble in each other. Hybrid materials are composites consisting of two constituents at the nanometer or molecular level. One of these compounds is inorganic and the other one is organic in nature. They differ from traditional composites where the constituents are at the macroscopic (micrometer to millimeter level). The use of hybrid materials in composite structural is becoming more nowadays [4], and the fibers can be arranged in various orientations during preparation of composite. ASTM standard [8] i.e. 10 plies are located symmetrically at ply position to get required orientation angle ply composites and which is prepared by hand-laid up with vacuum bag technique
