| Summary: | Hybrid composites are developed usmg compression molding
machine. The developed hybrid composite consists of a matrix material with
a combination of 2 fiber reinforcements. There are 3 types of fiber
reinforcements used in this study which are the woven glass, carbon and
Kevlar fibers. The matrix materials used are either epoxy or polyester. The
developed hybrid composite consists of fiber contents ranging from 15% to
45%. For polyester based composite, it is cured at room temperature while for
epoxy based composite, it was cured at a temperature of 80°C. Both of the
composite types were tested for its mechanical properties which are the
tensile test and impact test. Then, the microstructural structure of the
developed hybrid composite is analyzed.
Results showed that the tensile strength increases with the fiber
volume concentration. Hybrid composite reinforced with Kevlar and glass
possesses high impact properties compared to the hybrid composite
reinforced with carbon and glass fiber.
The Microstructural analysis showed that impact resulted in brittle
fracture in the case of carbon and glass fibers. While the Kevlar fibers show a
ductile type of fracture. |
