Abstract : The primary objective of the research is to develop a fundamental understanding of the effects of hygrothermal
exposure on Glass Kevlar Hybrid composites. Moisture absorption and its effects on the tensile, flexural and shear strength
of the composite specimens have been studied. Specimens were cut as per ASTM standards 3039, 790, 5357 for tensile,
flexural and shear test respectively. The specimens were conditioned by immersing them into distilled water and some
specimens in open environment for five different periods (every month). The aged and unaged specimens were tested under
Uni axial tension, Flexure (3-Point bending) loads and shear loads using Instron 3367 Universal Testing Machine (UTM).
The study on effect of different environmental condition on the composite material was investigated using Temperature cum
Humidity chamber with three different input parameters (humidity, temperature and time) and three levels (low, medium and
high) were chosen of India and Taguchi matrix was formed. The amount of degradation and the percentage of moisture
uptake of the aged specimens were investigated. The results indicated that, with the use of glass fabric in outer layer the
percentage of moisture absorption decreases thus reducing moisture degradation of composite. Good tensile, flexural and
shear properties was obtained for the glass Kevlar hybrid composite.
