Processing of Ti-SiC metal matrix composites by tape casting

Titanium-silicon carbide (Ti-SiC) continuous fibre composites are very attractive for aerospace applications. Although development of various components is under way; a cost effective method to manufacture lire material still has to be identified. Here, a tape casting technique is investigated as a viable method of producing the composites. It involves relatively large inexpensive titanium powder and simple apparatus. Furthermore , the powder particles ensure good fibre distribution, reduced consolidation time, and little damage to the reinforcement. Ir is shown that uniform powder tapes with goad packing density can be readily produced using appropriate casting parameters. Both thermogravimetry and mass spectrometry are resell to analyse the burnout process of a fugitive binder system? resell to produce the tapes. Removal of the organics. is found to take place in two stages separated by over 100 K. Composite materials processed by the tape casting route exhibit good fibre distribution and Mo signs of fibre damage. MST/4043.
