Abstract
For successful avoiding of the irregularities
and errors in the products from composite materials, it is
important to manage the whole production process in real
time. This applies to detecting certain irregularities
(positioning defects, bonding defects), controlling the robot
and process parameters.
This paper presents results from an experimental study
of the influence of embedded defects created during in -
situ laser automated fiber tape placement (LAFP), on the
mechanical properties of carbon/PEEK composites. Three
rings have been examined with different designs
[(0/±45˚)n], [(0/±30˚)n] and [(0/±90˚)n], in which gaps and
overlaps have been introduced during fiber placement.
The microstructures were characterized by optic
microscopy. ILSS tests were performed on samples from
rings and showed that the presence of a gap/overlap and
voids more than 3% affect mechanical behavior of pipes
but does not affect degree of crystallinity.
