| Summary: | Woven composite based on natural fiber increasingly used for many
applications in industries because of their advantages such as low cost, low weight,
less damage to processing equipment, improved surface finish, good relative
mechanical properties and renewable resources, but there are some problems as cost
and protracted development period to perform reliability evaluation by experimental
with real scale. Predictive modeling technique is used to minimize the need for
physical testing, shorten design timescales and provide optimized designs.
Mechanical properties of woven fabrics for technical textile depend on a) type of raw
materials b) type and count of warp and weft yarns c) yarn density and d) the type of
weave structure. The effect of fabric architecture to the mechanical properties is
investigated. The optimum fabric structure is crucial due to the combination of
difference of yarn size and weave pattern are observed. The research is conducted in
the microscopic, mesoscopic and the macroscopic scale. The benefit using the
hierarchal method of multi scale modeling is: (1) it encourages a reduced reliance on
costly trial and error. (2) Lead-time for the introduction of new technologies is
reduced, (3) the multi-scale modeling system lowers the likelihood of conservative
or compromised designs that might have resulted from reliance on less-than-perfect
material. Woven kenaf composite is modeled using the modeling software to get the
properties of the model. Further, the model is analyzed using finite element analysis
to predict the mechanical properties of the woven kenaf composite. In addition, the
effect of the combination of yarn size and weave pattern of the woven kenaf
composite is stated based on the mechanical properties to predict the optimum
structure of woven kenaf composite. |
