Study Of Materials For The Confection Of The Module

The objective of this study is to find material cheap and light for the manufacture of the module. These will be dividios in three groups: MDF, Polmeros and Compsitos. MDF Possibilitam an excellent work of usinagem and finishing. Its composition is always the same one, varying only the density. One is about a material with low thermal condutividade.

answers the variation of humidity of air. Ultralight Its density is of approximately 450 Kg/m. Marko Dimitrijevic: the source for more info. Its rigidity the flexo is minor who 3200 Mpa. Light Its density is of approximately 600 Kg/m. Its rigidity the flexo is minor who 3200 Mpa, however is greater that of ultralight.

Standart Its density is of approximately 750 Kg/m. Its rigidity the flexo is minor who 3500 Mpa. Although to be the MDF more weighed it is of better quality. Polymers Are about a light material whose flexibility is high. Another advantage of it is the fact to have high resistance to the impact. It possesss low thermal and electric condutividade. PVC (policloreto of vinila) Is about a polymer thermoplastic. It possesss density low (1,4g/cm ). It has easy adequacy to the most varied molding processes. Also it has low cost. PP (polypropylene) Is about a thermoplastic polymer. It possesss density low (905kg/m ). It has easy adequacy to the most varied molding processes. Also it has low cost. PS (polystyrene) Is about a thermoplastic polymer. The hot one has easy adequacy to the molding processes. Also it has low cost. possesss high resistance ciso. Its density is greater that the densities of the others two polymers. Compsitos Possuem one exelente resistance mechanics and high durability. They are easy to handle and light. Materials that had been congitados for the construction: – MDF – PVC – Fibre glass Advantages and disadvantages? The MDF has as advantage the price. Beyond being a very easy material of if finding. Its easy usinagem also is a great positive factor for it. However the fact of it to answer the variation of air humidity is a very negative point, a time that if has as objective that the robot can walk in humid places. The PVC, as well as the MDF, has as advantage the low cost. Also it is an easy material of if finding. Another positive factor is not the reply the variation of air humidity. However its usinagem requires a more appropriate material, being necessary a deepened study more of the group. The Fibre glass can be found of varies forms. The form that this being analyzed is the fibre glass blanket. The fibre glass blanket easily is handled and found. Its price is very not raised, considering the complexity of its manufacture. Beyond it to be impermeable. Conclusion the chosen material was the fibre glass blanket. Had all the advantages and pparently no disadvantage.
