Hemp fiber can be used as raw material for the manufacture of the gas tube. The results are stronger than the tubes of steel plates.

So the broadcast VOICE of the Ministry of SCIENCE and TECHNOLOGY for research and technology, Tuesday, June 9th, 2009 at 08.00-09.00 am viewing the topic of Hemp Fiber Gas cylinder, interview by phone with speaker Prof. Tresna p. Soemardi, Professor of the University of Indonesia, Depok.

According to the hemp plant can arguably Tresna versatile, ranging from the apical leaves until the roots can be utilized for a variety of needs, it featured as a raw material for military uniforms, can be created so the stem is firewood, and its leaves can be as livestock feed.

Rests on it, Tresna P Soemardi, offering alternative solutions tick raw material gas cylinder which has a comparable force even better than the steel plate. Despite their greater power, material derived from natural fiber composite epoxy was designed with light as well as a fixed stainless. Natural fiber composite epoxy in addition to the more environmentally friendly can also be produced

“Hemp Plant is rich in fiber (plant bast). Flax plants boehmeria nivea named as latin is easy to grow and grow in the tropics, so the material easy to obtain in Indonesia is very rich. Flax plants perfectly suited developed in the western part of Indonesia which has a wet climate. ” Details on the grounds that plants require a fair amount of rainfall throughout the year.

Advantages of hemp fiber strength supporting Component is reaching levels of cellulose 45 to 53 percent, whereas lignin as a component of composite materials to the detriment of just 21-26 percent. Hemp mechanical properties of the plant has a power 1050 Mega Pascal (Mpa), young’s modulus Gpa, 61.5 density 1.5 to 1.6 grams/cm3 and fiber length 60-260 millimeters. The use of fibre flax crops as composite material based on the consideration of the material was not easily cracked, more powerful, and can dampen vibrations.

“When gas Lpg composite tube accommodated in flax fibers, epoxy between gas Lpg with composite chemical reaction will not take place because of the good properties of epoxy remunerate once to the durability of resin. Moreover, material Composite tubes are pastis. That is, at the moment given the huge burden of declining due to the nature of elasticity concentrations that exceed the limit of the material. The gas tube from the flax fiber is very light and resistant to rust, Eco-friendly, and more artistic. “explained Tresna at length.

Yet Tresna gives an account, the strength of a composite material is determined by the properties of pembentuknya materials. In addition the strength is also determined by the orientation angle and the thickness of the layer. If the strength of the fiber and matrix, there is a difference which is quite far away, doing so will cause the flax fiber and matrix broken.

“In the process of making composite, there is a failure it featured that could be caused by factors of processing errors. In order for composite fiber flax epoxy tube not scratched or hit with hard objects, it will be good coated sheet aluminum. Nevertheless, there is a lack of fiber flax, which could become a powder or powder or it could be subjected to corruption or destruction. Even in the long run could experience fragility. “
