excellent thermal resistance and mechanical strength.
For example, the materials can be used for electri-
cal and electronic instruments or mechanical parts, as
laminated and reinforced products [8]. Fields of appli-
cation are aerospace, electrical coatings [36], and in
automotive components.
8.4.1 Reinforced Resins
A reinforced resinous composition can be obtained
by mixing a PEN with a fibrous reinforcing material,
followed by kneading. The amount of fibers is in the
range of 5–60%. If the amount of fiber exceeds 60%,
the PEN will not be desirably distributed through the
voids of the reinforcing material. The kneading tem-
perature is preferably 340–360
◦
C and the kneading
time is 1–3 min [8].
