Densification of High Thickness C/C Composites by Chemical Vapor Infiltration

TL;DRAbstract

In the last decades the research on composite materials have been acquiring importance due to the possibility of increasing the material mechanical performances while contemporary decreasing both mass and volume of the structures. Composites are widely used in space vehicles and systems as structural materials, thermal blankets, thermal control and conformal coatings, adhesives, lubricants, etc. Exposure of composites to the space environment may result in different detrimental effects via modification of their chemical, electrical, thermal, optical and mechanical properties as well as surface erosion. The major degradation effects in composites are due to the exposure to atomic oxygen, vacuum ultraviolet, thermal cycling and combined effects during orbit period and plasma during re-entry phase. Among all, carbon-based ceramic composites are the most promising materials for space applications, due to their impressive thermal stability and lightweight. Carbon-Carbon (C/C) composites hav
