PENGARUH FRAKSI VOLUME FILLER TERHADAP KEKUATAN BENDING DAN KETANGGUHAN IMPAK KOMPOSIT NANOSILIKA – PHENOLIC
ABSTRACT: The objective of
this research is to investigate the effect of filler volume fraction on bending
strength and impact toughness of nanosilica-phenolic composites. The research
materials used were nanosilika powder, LP-1Q-EX phenolic resin, MEXPO catalyst
and P-EX promotor. In this research, the filler volume fraction of nanosilica
were varied into 10-60%. The composites were produced by using a hand lay-up
method. All specimens were post cured at 100˚C for 60 minutes. The specimens were
conducted with universal testing machine and impact izod testing machine. The
fracture surfaces of the specimens were observed by using scanning electron
microscopy (SEM). This result showed that the addition of nanosilica increased
the bending strength and impact toughness. The maximum bending strength and
impact toughness occured on the specimens whose 30% of nanosilica (97,01 MPa
and 8134,70 kJ/m ). SEM images showed better interaction of filler and matrix
at 30% volume fraction of nanosilica.
