Materials of Tensiles Architecture
Tensile Structure Membrane materials
Now-a-days varieties of materials are used as tensile membrane materials. PVDF coated PVC, HDPE, and Teflon coated glass fibers are normally used as good quality tensile fabric materials. Now the fabric those are being used as standard materials for tensile structure should have the following properties.
Strip tensile strength
Grab tensile strength
Trapezoidal tear strength
Tongue tear strength
Adhesion strength
Flame resistance
Finished weight
Base fabric weight
Available Top coatings
Resistance to cold crackin
Dead loas
Structural properties
Life expectancy
These basic data are important to measure the relative strength of the fabric under tension. If anything goes wrong the fabric may rupture, and there is a chance of the extension of the damage in and around that are.
All architectural textiles use top coating for auto cleaning purpose. The topcoats are acrylic solutions, polyurethane-acrylic solutions, PVDF solution coats or a PVF film lamination. The top coat prevents the fabric from sticking the dirt on its surface and helps it to clean with water easily.
The structural properties of the fabric are most important to ascertain the long term performance of the fabric. The structural analysis is required before the fabric selection and most of the cases the manufacturer provides all sorts of data regarding this. The basic property depends on the unit load versus unit elongation. Sheer strain, sheer strength and Poissons ratio are the important parameters to analyze the structural properties of the fabric. But there are other properties those are required to analyze the full performance of the fabric.
Shading coefficients
Solar, optical, thermal performance data
Acoustical data
Dimensional stability
Colorfastness
Cleanability
Seam strength and stability
Construction method
General handling ability
