Question for Development of Bamboo Materials for Body Speed Boat Application
Andi Lamappasessu (a), Dwi Rahmalina (a*)
What is the drawbacks of bamboo materials for body speed boat application?
Replies:
The drawback that may occur is that it is flammable, however, we are currently
conducting research to anticipate using environmentally friendly additives.

it is interesting that bamboo can be developed in such a way as to increase its
mechanical ability. how to make FRP, FBR etc? is it with a mold system or is there a
special machine?
Replies:
Make FRP with the hand lay up or composite method using a mold, no need for a
special machine. To make FRP using fiberglass, resin, hardener and gelcoat. Make BFR
using bamboo fiber, resin, hardener. make BSR using bamboo strips, glue, resin (if
needed) and Hardener.

There is no character about the beauty of the speed boat except for the desire of the
speed boat factory to attract the attention of the costumers and buy them.
Dear Mr Andi Lamappasessu, I am interested in the research you are doing, I have
asome questions:
1. in the presentation, it was explained that the fabrication used a hand lay up
process on the FBR and FRP composites right? How many fiber layers are used in
the composite?
2. can the BSR be used in the production of speed boats in large quantities? is it
more efficient and effective than FRP?
Replies:
1. Yes, that^s right. In the process of making FRP and BRP composites using the hand
lay up method. In FRP there are 5 layers for a thickness of 4.08 mm. While BRP has
2 layers for a thickness of 4.09 mm.
2. The BSR type can be used for making large amounts of speed. Yes, it is more
efficient because it uses less resin, and it is more effective because it can easily
follow the shape of the mold and is environmentally friendly
The body speed boat is very prone to cracking because it works under dynamic
loads. What is the value of the crack resistance rate of fatig bamboo ?.
Replies:
The Bamboo Surat (Gigantochloa pseudoarundinacea) experienced cracks during the
testing process with dimensions: 2 layers (strips), wide : 15 mm, thickness : 4.09 mm
is ranging from 77 N/mm2 to 125 N/mm2.
I am very interested in Mrs. Dwi Rahmalina^s research. For the application of this bamboo material when it is applied to the body of the speed board, is it resistant to animal attacks or not?

Dear Mr. Suroto Munahar,
Bamboo material for speed boat body, resistant to termite and animal attacks.
The traditional way to preserve bamboo can be done by:
Control of cutting time, soaking bamboo in still or flowing water, smoking bamboo,
dipping with lime (CaOH2), roasting bamboo.
Modern preservation of bamboo is done by chemical use : Boron compounds, Zinc
Chloride/Copper Sulphate, NaPCP (Sodium Penta Chloro Phenate), CCA (Copper
Chrome Arsenic) and ACA (Ammoniacal Copper Arsenate), CCB (Copper Chromium
Boron), Carosete/Ter.
Water based preservatives : There are water-based bamboo preservatives that have
permanent properties such as CCB (Coper Chrome Boron) and non-permanent ones
such as Boron-Boric Acid.
