thermograms of the composites present only the melting event.
The glass transition temperature is hardly observed and the cold
crystallization phenomenon is absent, indicating that the materials
were highly crystalline after the previous cooling at 2 ◦C/min. It
must be noted that a shoulder-melting peak appeared instead just
before the main melting peak. The shoulder and the main transition
were noticeable for all the samples and were noted Tm1 and
Tm2, respectively. Each melting peak is the signature of a crystalline
lamellae population essentially characterized by its thickness or its
perfection.
