Figure 9.21 Tensile strength for PEEK LT1 (a) and
LT1CA30 (b) specimens with different type of
Spondycoat coatings compared with original material
(uncoated) and partially processed specimens (sand-
blasted). The whole cross-sectional area (substrate
and coating) is considered for calculation.

and LT1CA30 (b) specimens with different type of coat-
ings, compared with original material (uncoated) and
partially processed specimens (sandblasted). Values
are normalized to effective substrate cross-section.
