During streamlined stacking of composite structures, encounters extreme contact and tall surface temperatures. In this setting, carbon-epoxy shell is utilized as inner auxiliary layer and carbon-phenolic shell is utilized as outside layer for generation of multi layered composite structure. Autoclave curing of phenolic composites includes a complex administration of time – temperature -weight cycle where determination of weight application point is the foremost critical parameter, chooses the quality of the component. Early weight application with regard the gelation produces tar starved component, which corrupt the warm execution of the component while late weight application produces more porosity within the component due to catching of volatiles created due to curing chemical response. Generation of tall tar substance and least void conveyance is most basic and which is achieved by analysing the volatiles advanced amid the method.
