Investigations to Model and Analyse the OHC Strength of Hybrid Composites

size: 9pt; color: rgb(0, 0, 0);">In recent years, the utilization of hybrid polymer matrix composite materials in many engineering fields has increased
size: 9pt;">tremendously. The present investigation is devoted on fabric-reinforced hybrid composite laminates with different volume
size: 9pt;">fractions of the constituent materials; epoxy resin, plain-woven glass fabric, and textile satin fabric. Fracture toughness of
size: 9pt;">a material has immense importance in the determination of the resistance of the material to crack propagation. Hence this
size: 9pt;">article explores the findings of the experimentation on the compressive strength and fracture toughness of fabric-reinforced
size: 9pt;">laminates with 0/90size: 4pt;">O size: 9pt;">& ± 45size: 4pt;">O size: 9pt;">orientation with five notch configurations. The fracture toughness has been found to increase
size: 9pt;">continuously with increased volumes of glass fabric and it is less dependent on notch size upto certain limit. Data collected
size: 9pt;">during experimentations are validated using analysis of variance (ANOVA) technique. Percentage contribution of each
