Abstract

Natural fiber reinforced sandwich composites have been of keen interests to researchers as a result of their low cost, moderately good mechanical properties, and biodegradability. The main attention of the present work lies on the eco-friendly honeycomb structures for sandwich panels. This paper investigates the mechanical characteristics of flexural and fracture strengths of the sandwich panels involving polypropylene as its core and treated flax fabric fiber reinforced polymer matrix composites as face sheets. Taguchi's design of experiments is implemented in the experimental analysis. The influence of fabric orientation and surface treatment on the properties is reconnoitered. Analysis of Variance (ANOVA) is employed to study the influences of different parameters on flexural and fracture strengths of sandwich panels.
