Gfrp Composite

Silicon Carbide/GFRP reinforced matrix composite and SiC matrix composite has been developed by using hand layup and resin casting methods respectively. The GFRP reinforced polymer composite is made by sandwiching two layers of GFRP in between the SiC material. The resin used for the preparation the samples are epoxy and polyester, for both SiC/GFRP composite and SiC composite. An Arcan fixture with butterfly specimen is used to measure the fracture occurring in various modes of the polymer composite. The objective of the proposed testing method is to determine the variation in the stress value depending on the resin material as well as the influence of GFRP in the strength of SiC polymer composite. Results from the tests are analyzed to show that the epoxy resin is better for tensile strength, in both Sic/GFRP reinforced and SiC composite material.

Static And Dynamic Analysis

This paper discusses about the weight reduction in the wing structure that improves the productivity and performance of an aircraft wing. Decrease in the mass of the wings has higher significance compared all other air craft parts Aircraft wing structures are analyzed with LM25 and a metal matrix composite material which is a mix of LM25 and Silicon Carbide (SiC) where in aluminum is the base metal and silicon carbide is added in different weight proportions. By varying silicon carbide percentage in LM25 four types of samples are prepared utilizing stir casting process. The young's modulus, Poisson's ratio and thickness of every sample are determined cautiously by exposing the sample to tensile test and hardness test. By looking at the material properties acquired tentatively ideal level of silicon carbide in aluminum is found. Static basic investigation is completed in ANSYS by contributing the properties of the ideal example which are acquired tentatively. The outcomes acquired from ANSYS for pure AL25 and metal matrix composite (SiC) are compared. By looking at the outcomes it is discovered that composite material has preferred material properties and stresses over LM25.

Abstract The presented work describes the results of examination of the mechanical properties of castings made either of AlSi9Mg alloy matrix composite reinforced with short carbon fibre or of the pure AlSi9Mg alloy. The tensile strength, the yield strength, Young’s modulus, and the unit elongation were examined both for initial castings and for castings made of the remelted composite or AlSi9Mg alloy. After preparing metallographic specimens, the structure of the remelted materials was assessed. A few non-metallic inclusions were observed in the structure of the remelted composite, not occurring in the initial castings. Mechanical testing revealed that all the examined properties of the initial composite material exceed those of the non-reinforced matrix. A decrease in mechanical properties was stated both for the metal matrix and for the composite after the remelting process, but this decrease was so slight that it either does not preclude them from further use or does not restrict the range of their application.
