Summary: This study investigated a novel carbon foam composite reinforced by chopped glass fibers, revealing that adding 7% glass fiber additives resulted in optimal mechanical properties and thermal conductivity. The composite exhibited improved shear strength and higher thermal conductivity compared to pure carbon foams. Despite the presence of tiny open pores, the carbon foam composites showed good thermal insulation performance at both room temperature and 800 degrees Celsius.

Summary: This paper prepared, characterized, and evaluated a calcined kaolin-based geopolymer foam. Different dosages of hydrogen peroxide foaming agent were added to the geopolymer paste at various percentages. The effect of hydrogen peroxide and different curing temperatures on physical properties, mechanical characteristics, and pore distribution was studied. The results showed that the geopolymer foam had acceptable compressive strength values, low thermal conductivity, and was cost-effective for insulating construction materials.

Summary: We successfully fabricated large, strong, crack-free carbon/carbon (C/C) composites with excellent load-bearing capacity, thermal stability, and thermal insulation through a high-pressure-assisted polymerization method combined with ambient pressure drying. These composites, featuring an aerogel-like carbon matrix and low carbon crystallinity fiber reinforcement, are ideal for the ultrahigh temperature thermal protection of aerospace vehicles where both excellent thermal-insulating and load-bearing capacities are required.
