The autoclave cure process is the representative composite fabrication technique for high quality composite materials for the aerospace and defense industry application. After lay up and vacuum-bagging in a complicated sequence, the several composite material needed in autoclave curing are cured under controlled temperature and pressure. The autoclave curing, in which the total cure process requires at least 4-6 hours, is a very expensive process. Therefore, the determination of an optimal cure process for composite prepregs is very important for guaranteed quality as well as being important economically. Theoretical models cannot be proved because of the lack of experimental methods. The experimenter must run many batches of autoclave curing trial and error at the different curing temperatures and pressures to obtain a sufficient amount of data which can experimentally determine the optimal cure process. Because this invention can continuously monitor the change of thickness of the composite laminate during curing, this measuring system, which can determine the condition of an optimal cure process, is an excellent device to obtain the degree of curing and variation of thickness of a prepreg which is optimal in physical and mechanical properties.
