There is a good overview of trends in composites usage given by the Rand report,
Military Airframe Costs (MR1370):
RAND | Monograph/Reports | Military Airframe Costs: The Effects of Advanced Materials and Manufacturing Processes
In addition to lots of cost information, this volume includes a number of graphs that compare the usage of titanium and composite materials among US-developed fighters and bombers over the past 40 years. The graphs appended below should give you an idea of trends.
