Your answer is somehow general; meaning that you need to clarify what kinds of detail your are looking for.
In common, for composite manufacturing and applying tests to your produced materials, mechanical tests such as compression, tensile, and bending are concerned. After molding and preparing your specimens, you need to investigate the mechanical behaviors of your samples. for this, you need the tensile tester (such as Zwick or Instron Universal tester) for study the behavior of your samples under uni-axial loading conditions. Or, you need to employ compression and three-point bending tester for analyzing the compress-ability and or rigidity of the samples.
Moreover, the condition of molding including the applied presser of molds, the temperature, rate of the resin transferring, rate of cure operation, and etc must be under consideration if the process condition effects on the sample characteristics is of your main concerns.
