Reducing Poverty through

ECO-WOOD SUBSTITUTE MOLDED DOORS

Global Warming and Poverty (GWP) are the biggest problems of modern world. Both are corollary to one another. We need to work on the two simultaneously. We do that here by developing and commercializing an ECO-WOOD SUBSTITUTE system and converting the same into MOLDED DOORS. These are produced with less machinery (and hence less energy), and instead, using locally available skilled Human resource. Each ton of these Molded Doors would substitute approximately 1.5 T of Wood logs, which would come from double that weight of original trees. One thousand ECO-WOOD SUBSTITUTE MOLDED DOORS would offset cutting trees in approximately 3.75 hectares (9.3 acres) of Wood land/Forest. A million Molded Doors would offset tree cutting in 9,300 ac of forest/woodland. Further, there is the added social benefit that Each 3,000 T Molded Doors Plant would offer direct employment to 300 local Village youngsters – both men and women

Zero-Carbon Molded Door

HIGH-QUALITY CLEAN-TECH MOLDED DOORS

Here are PRODUCTS that conserve Forests, reduce Global warming, reduce wastes/recycling wastes, providing local jobs, improving National Economy, and helping Customers enjoy the BEST Products at affordable cost.  Natural Fibers such as Coconut leaf splinters, Coconut Husk fibers, Sawdust, Banana Fibers, and many others have very high STRENGTH-to-WEIGHT ratio. This means, on a “weight basis” appropriately designed and engineered products would have high strength, compared to other traditional materials. Further, by converting these Natural Fibers with various specialty Polymers we could arrive at excellent properties that would never be possible using wood alone. Here we have developed extremely Strong, Durable, Water-Proof, Insect-Proof and Warp-proof Composites that combine FORM, FUNCTION and PERFORMANCE. The Composites are Single-Piece, without any joints and planking. Their Aesthetics would make even natural wood just “ordinary looking”

Environmentally Neutral Engineering Composites for Boats and Aircrafts

TRADITIONAL ENGINEERING MATERIALS

Steel, Aluminum, Brass, Bronzes, Plastics, Polymer Composites and Wood are the most used traditional engineering materials. These have certain properties as follows: (CLICK on the TABLE to ENLARGE have a better View)

Comparative Design Advantage of Hybrid Bamboo Composites:

In order that we are able to arrive at “optimum” engineered material system for a particular design need, we shall compare the “Rigidity factor” based on Low Carbon Steel (which is the standard structural engineering material)

The average thickness of Steel sheet material needed for the hull of a small 20 ft Dinghy that needs to be “seaworthy’ is 6 mm. The various thickness factors for the Composites (based on equivalent Rigidity factor) are presented below:

Fiber (40% uni-directional) Tensile Strength Sp.wt Sp. Tensile Strength Engineered Section Wt per Sq m Rigidity Modulus Fabrication Cost Factor
(MPa) (kg/m3) (m) (cm) Kg (Kg-m2) (Rs/ Sq m)
Low Carbon steel 400 7850 5095 0.6 47 3.78 5640
Bamboo (40%) 293 600 48833 1.36 8.16 3.84 3060
Bamboo-Glass 350 703 49786 1.36 9.56 3.82 3657
Hybrid Bamboo1 440 688 63953 1.26 8.67 3.8 7700
Hybrid Bamboo2 438.2 695 63050 1.2 8.34 3.9 9908
Kevlar 49 1298 1243 104424 1.01 13.11 3.88 33319

 It is noted that we could engineer superior structures using both 40% bamboo composite and bamboo-glass composites. The cost factors would be lesser than that of Low carbon steel structure, even at 50% excess thickness levels in the Bamboo composite structures. That would mean far superior Strength-Rigidity factors in the resultant engineered systems. See the Table below:

Fiber (40% uni-directional) Tensile Strength Sp.wt Sp. Tensile Strength Engineered Section Wt per Sq m Rigidity Modulus Fabrication Cost Factor
(MPa) (kg/m3) (m) (cm) Kg (Kg-m2) (Rs/ Sq m)
Low Carbon steel 400 7850 5095 0.6 47 3.78 5640
Bamboo (40%) 293 600 48833 2.04 12.24 12.96 4590
Bamboo-Glass 350 703 49786 2.04 14.34 12.89 5485

It is further noted that even at double the “minimum thickness” for “steel equivalent” Rigidity factor, the weight factor is only about one-fourth of steel … allowing us to have greater Strength-Rigidity-Economics
