A CRITICAL REVIEW OF COMPOSITE MATERIALS FOR BUILDINGS, THERMAL, AEROSPACE AND CRYOGENIC APPLICATIONS

Patrick Land et al [1] presented in their technical paper the use of off the shelf non destructive testing equipment utilizing Fringe projection and open source software to rapidly evaluate a series of composite panels. These results are then verified using destructive analysis of the panels to prove the reliability of the rapid non destructive testing methods for use with evaluating carbon composite panels. This process allows us to rapidly identify regions of geometric intolerance or formed defects without the use of expensive sub-surface scanning systems, enabling a fast and cost effective initial part evaluation system. The focus of this testing series was on 6mm thick pre-preg carbon-epoxy composite laminates that have been laid up using (AFP) and formed using Thermal Roll Forming . G Ramanjaneyulu and R Rajendran [2] presented in their technical paper POM/Graphite and POM/MoS2 composites were prepared using twin screw extruder for 2 and 6% compositions of fillers. The samples were studied for impact strength and wear loss using molding machine. The wear test of the samples was carried out using pin on disc wear testing machine at various loads. Impact test of the samples was carried out by impact testing machine. The wear of the POM/MoS2 composites decreased compared to POM/Graphite composites.
