HISTORY
developed by a US navy contract for the development of 28-ft long personal boat in 1946
Harold John Pollard and John Rees in between 1952 – 1956 plant for fibers and asbestos
fully developed for general aerospace applications in the 1980s
Types :- LCM,RIM,SRIM,RRIM,RTM

Advantages
Design Flexibility
Faster Production
Labor Savings
Dimensional Tolerances
Surface Finish
Lower Material Wastage
Very large and complex shapes can be made efficiently

Disadvantages
Greater Tooling Design and Construction Skills Required
Higher Tool Cost
Reinforcement loading may be difficult with complex parts
Mold design is complex
