The present work reinforces material for polymer composites alternative to the use of Epoxy resin LY556, Glass – Woven and Chopped. The hybrid composite material   is a combination of two or more different types of fiber in which one types of fiber balance the deficiency of other filler. Iron powders are used as a filler material. The composite laminates were fabricated by varying weight percentage of 0, 1, 3, & 5 of Filler material using hand layup technique. The mechanical properties of the prepared composites materials were characterized in terms of tensile strength and impact (Izod) tests as per ASTM standards. At addition of 3 wt. % of iron powder the tensile strength was improved by 44% and impact strength by 94.2% when compared with neat polymer composites. The reason for the enhancement was wonderful interfacial bonding with fiber and polymer matrix.

This research details a procedure for the systematic design of foot orthotics based on simulation models and validation of the same with subsequent experiment. The present model may ultimately to replace the use of empirical tables for the designing of foot orthotics in accordance to the weight and activities of end-users. This present model is so general that it can simulate different kind of orthotics, loading conditions and material properties to give the desired output. Finally, the proposed model and the corresponding results may lead to the form of design basis for new generation foot orthotics. The methodical approach to the development of engineering analysis models using the FEA technique. Orthotic devices have been commonly made from plastics like polypropylene. However, insufficient mechanical properties, labour intensive preparation process, long client’s visiting times urge us to seek an alternative. Presently, two different advanced composite materials (Glassfiber, Basalt-fiber) have been chosen for the analysis purpose to achieve the low weight and High Strength.
