PENGARUH VARIASI ADHESIVE TERHADAP KEKUATAN BENDING KOMPOSIT CANTULA 3D-UPRs DENGAN CORE HONEYCOMBKARDUS TIPE C-FLUTE
Abstract: The aim of
research is to
investigate the effect
of adhesive variation on flexural
strength of UPRs
Cantula 3D Sandwich
Composite with C-Flute corrugated cardboard honeycomb core. The adhesives
applied in this research were some
type of polyester such as 157 BQTN EX, LP 1Q EX, FW 21 EXL, and type
of epoxysuch as Versamid 140. The Hand
lay up methode
was used to
make UPRs-Cantula 3D composites
with 30 %
weight ratio content.
The flexural strength
test was according to ASTM C 393
and the observation
to surface fracture from the specimen of flexural strength test was done
by Scanning Electron Microscope. The
result indicated that
the highest flexural
strength was 7,98
MPa that reached by
adhesive Versamid 140.
The observation of
surface fracture composite showed
that UPRs Cantula
3D Sandwich Composite
with adhesive Versamid 140, have less pull out and shortfibre fracture.
