| Summary: | This report basically presents the research that had been done on the topic "The Study
of Tensile Failure on Thin Plate Hybrid Composites with Drilled Holes". This study
involves using had lay up technique on fabrication of 2.0mm thickness plate samples of
55% volume fraction of woven cloth carbon fiber and woven cloth glass fiber of
orientation of0/90/0/90 in polyester matrix. Using a 5mm HSS drill bit, the samples are
drilled using CNC drilling machine with feed rate of 0.05mm/rev and 0.15mrn/rev, and
spindle speed of690, 790, 1250, 1340,2500, and 2700 RPM. The damage extension due
to the drilling are observed and measured using 3D Non Contact machine and the
damage factor are carried out to analyze the effect drilling parameters to the samples.
Surface roughness of the feed rate is measured using Profilometer for alternative to
measure the drilling effect. Tensile test using UTM I OOkN machine is used to acquire
the tensile properties of each of the sample along with the undrilled ones. Analysis
including using Scanning Electron Microscopic for microscopic view for the surface of
the drilled area, delamination extension due to the tensile force, damage factor of drilled
area and surface roughness are compiled together and compared to investigate the
relation of each of the data to the tensile properties. |
