ANALYTICAL HIERARCHY PROCESS BASED DECISION MAKING FOR FABRICATING CFRP FOR SPACE APPLICATIONS USING NANOMATERIALS

摘要

Carbon fiber reinforced polymer (CFRP) has limited uses due to low electrical and thermal conductivity compared to the conventional metals and alloys. The carbon based nanomaterials single walled carbon nanotubes (SWCNT), multiwalled carbon nanotubes (MWCNT), and reduced graphene oxide (rGO) are used as filler material in CFRP composites to enhance its electrical conductivity, thermal conductivity, and shielding effectiveness (SE), which are essential criteria for designing the space components. The selection of appropriate filler is a challenging task in order to achieve the specific properties required for space components. The analytical hierarchy process (AHP) based decision making approach is helpful to select the nanomaterial. This paper analyzes the multiple criteria based on results obtained from experimental testing and functional requirements. This paper provides suitable nano-fillers for fabrication of radio frequency and structural components for space applications.
