Ringkasan Produk
Multi-walled carbon nanotubes (MWCNT)
have been studied as a nanofiller for polymer
nanocomposites. To improve its compatibility
with its matrix, the nanofiller surface property
is normally modified. In this work, a MWCNT
was modified using an organic surfactant,
dioctadecyldimethyl ammonium bromide
(DODAB), a double-chained quaternary
ammonium surfactant. The modified
MWCNT was then characterized using FTIR
spectroscopy and thermogravimetric analysis
(TGA). FTIR spectrum of the modified MWCNT
showed that DODAB functional groups
were present suggesting that DODAB were
successfully attached to MWCNT. Meanwhile
the TGA thermogram of the modified carbon
show that there were weight losses indicating
the presence of both the surfactant and
the MWCNT in the product. The success
this MWCNT modification may marks new
composite synthesis that lead to materials that
suitable to be for military applications.
Nowadays, there is an increasing demand for
full three-dimensional (3D) data for engineering
related industries such as automotive,
aerospace, manufacturing, environmental
analysis and also for architectural works. An
object can be converted into 3D model using
traditional method (manual measurement) to
mechanized instruments such as coordinate
measuring machine (CMM) and 3D scanner.
However, management and modeling of all
these kind of information is complicated and
accuracy level varies from different methods.
For larger objects, 3D model development
provide a monumental task due to the
unavailability of tools to measure either
manually or with advanced instrumentation.
Moreover such process is time consuming,
tedious and prone to measurement errors.
Photogrammetry, generally used for aerial
topography mapping provide an alternative
solution to resolve this issue by digitizing
images into digital data. An integrated
digital photogrammetry system is defined as
hardware/software configuration that produces
photogrammetric products from digital imagery
using manual and automatic techniques.
This project is focused on developing a 3D
solid model of an armored vehicle using
photomodeling technique. The main objective
is to obtain the detail computer aided
drawing (CAD) of SIBMAS AFSV by using
PhotoModeler, SolidWorks & CATIA V5. The
task involves object marking, photography of
individual sections, digitization of images and
CAD pre-processing work. The output from
this project can be utilized in the engineering
analysis such as finite element and computer
fluid dynamics simulation works.
