Abstract
A method for analyzing semifinished products including reinforcing fibers having an essentially unidirectional orientation and a thermoplastic resin, including a first and a second test for measuring the thickness of a stack of semifinished products over time during the compression thereof and for determining the equivalent homogeneous viscosity of the stack; determining the total thickness reduction of the stack of semifinished products during the first test; determining the ratio of the equivalent homogeneous viscosity of the stack from the second test to the equivalent homogeneous viscosity of the stack from the first test; and determining the ratio of the thickness of the stack from the first test after a reference time starting from the moment of the onset of melting of the stack of semifinished products, to the thickness of the stack from the first test at the moment of the onset of melting of the stack of semifinished products.
