Abstract

The paper deals with the fabrication and flexural properties studies of stitched core foam sandwich structures by varying thread TPI(Twist Per Inch).10 mil silane treated open form E – glass fabric was used as a face sheet. Divinycell foam H- 80 was used as a core material. The perforated foam was placed in between the face sheets and hand stitch method was used for stitching the face sheet and the foam by glass yarn (37 1/5) of 3, 3.8, 5.3. The panels were fabricated under Vacuum bag moulding process The flexural strength and flexural deflection of fabricated specimens were determined through three point bending test (ASTM C 393-62). A significant increase in flexural rigidity of foam was observed in the panel stitched with thread of 3 TPI when compared with other layers.
