OPTIMASI PARAMETER PROSES VACUUM ASSISTED RESIN INFUSSION TERHADAP SIFAT FISIK DAN MEKANIK KOMPOSIT POLYESTER FIBER GLASS
Abstract: Vacuum assisted
resin infusion is a method which was used to manufacture composite review. The
method of vacuum assisted resin infusion (VARI) method using inversely
proportional to non-vacuum methods. Requires singer method air-room safe hearts
printing. VARI process can be reducing the effects of fouling that much happens
on as non vacuum processes which raises less than optimal properties of
composite materials. Problems That study is to determine review process
parameter optimization of vacuum assisted resin infusion against physical and
mechanical properties of composite polyester fiber glass. Knowing the influence
of vacuum pressure treatment and hardening of composite processing time in the
manufacturing process of composite with VARI method in the physical and
mechanical testing of surface roughness, tensile and impact. Variations were
used that vacuum pressure of 0.2; 0.5; 1.0 bar and a hardening of composite 2
hours; 4 hours; 6 hours. From the research VARI composite manufacturing method,
surface roughness values obtained, the tensile strength and the best impact
occurs at various pressure of 0.2 bar and a time of 2 hours hardening composite
has a value of 0.498 μm surface roughness, the value of 27.344 MPa tensile test
and impact test values 47.859 J / mm2.
