“…Thus the fibers were not exposed and did not participate to the joint formation. The real area of contact (flat zones) is smaller than the nominal one, typically of the order of 60 to 80% for the 3D composite specimens [9,11]. The preceramic polymers used in the joining experiments were: a methylhydroxyl-siloxane (SR350, General Electric Silicone Products Div., Waterford, NY) and two polycarbosilanes (PCS, Dow Corning X9-6348, and allylhydridopolycarbosilane (AHPCS, Starfire Systems, Watervliet, NY).…”
