Composite and Polimer Manufacturing

So today is my first class in "Composite and Polimer Manufacturing" and i want to share my note with you all.

so this is the example of composite material

then let's talk about what is composite material

from http://en.wikipedia.org/wiki/Composite_material :

 Composite materials, often shortened to composites or called composition materials, are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct within the finished structure.

  Material Komposit atau lebih sering disebut dengan komposit adalah material yg dibuat secara teknik atau alami yang terkomposisi oleh dua atau lebih material yang memiliki ciri-ciri fisik dan kimia yang berbeda dengan kondisi tetap terpisah dan utuh pada struktur jadi dari material komposit.

Composite is compose from  fiber and matrix (e.g resin)
Komposit terdiri dari fiber dan matriks (cth: resin)

fiber is used as a bone in structure and resin is used as a flesh of the compound.
fiber digunakan sebagai tulang dalam komposit dan resin sebagai dagingnya

a common fiber that used as composition of composite is fiberglass
bahan serat yang paling sering digunakan adalah fiberglass

Natural fiber that must be reconsidered to use in manufacturing is fiber from empty bunch of palm.
Serat alami yang perlu dipertimbangkan untuk digunakan dalam bidang manufaktur adalah serat dari tandan buah kosong kelapa sawit.

from http://en.wikipedia.org/wiki/Fiberglass :

Fiberglass (or fibreglass) (also called glass-reinforced plastic, GRP,glass-fiber reinforced plastic, or GFRP), is a fiber reinforced polymer made of a plastic matrix reinforced by fine fibers of glass. It is also known as GFK (for German: Glasfaserverstärkter Kunststoff).
Fiberglass is a lightweight, extremely strong, and robust material. Although strength properties are somewhat lower than carbon fiber and it is less stiff, the material is typically far less brittle, and the raw materials are much less expensive. Its bulk strength and weight properties are also very favorable when compared to metals, and it can be easily formed using molding processes.
The plastic matrix may be epoxy, a thermosetting plastic (most often polyester or vinylester) or thermoplastic.

Fiberglass atau serat kaca adalah serat polimer yang diperkuat terbuat dari matriks plastik yang diperkuat oleh serat-serat kaca yang baik. Kekuatan serat kaca lebih rendah dari serat karbon dan kurang kaku tetapi material sangat tidak rapuh  dan bahan mentahnya lebih murah untuk diperoleh. Karena kekuatan dan beratnya  material ini sering dipilih jika dibandingkan dengan logam dan mudah dibentuk dengan menggunakanan cetakan.
Matriks plastik yang digunakana bisa epoxy, plastik thermoset (sering digunakan polyester dan vinylester ) atau thermoplastic.

This is the fiberglass that used in our lab

Than let's talk about matrix that used

from http://en.wikipedia.org/wiki/Resin :

Resin in the most specific use of the term is a hydrocarbon secretion of many plants, particularly coniferous trees. Resins are valued for their chemical properties and associated uses, such as the production of varnishes, adhesives and food glazing agents. They are also prized as an important source of raw materials for organic synthesis, and as constituents of incense and perfume. 

Resin adalah sekresi hidrokarbon dari beberapa tumbuhan , biasanya jenis pohon jarum (cth pohon cemara). Resin dihargai atas komposisi kimianya  dan penggunaannya dalam pernis, bahan perekat dan bahan pelapis dalam makanan. Resin juga merupakan sumber bahan mentah penting untuk intesis organik dan bahan dasar dupa serta parfum.

Resin is divided to two which is termoplastic resin and thermoset resin
Resin terbagi dua yaitu resin thermoplastic dan resin thermoset.

This is the different

from http://www.sandwichpanels.org/articles/article_thermoplasticresin.html :

Thermoset resins generally come in liquid form, and when mixed with a catalyst, a chemical reaction occurs forming a solid. Thermoset molecules crosslink with each other during curing, thus once cured, they cannot change. Below are features of thermoset resins.

Resin thermoset biasanya berbentuk cair dan ketika bercampur dengan bahan katalis membentuk benda padat. Thermoset saling berhubungan menyilang antar molekulnya ketika memadat, sehingga bentuknya tidak dapat diubah kembali. berikut merupakan ciri-ciri resin thermoset :

Thermoset Resin:

Pros
Easy to process and laminate
Does not necessarily need pressure or heat to form
Generally inexpensive
Generally stronger than thermoplastics
Generally better suited to higher temperatures then thermoplastics

Cons
Often release emissions known as volatile organic compounds (VOCs)
Cannot be recycled or reclaimed easily
Short workable pot life, with some exceptions
Less-than-perfect surface finish

Common Types of Themoset Resins
Epoxy
Polyester
Vinylester
Polyurethane
Phenolic

Thermoplastic resins have molecules that are generally not crosslinked, meaning, the resin can be repeatedly melted and reused. Usually, no chemical change occurs when thermoplastic is cured. Thermoplastic resin usually starts out in solid pellet form, and changes shape with the addition of heat and pressure. Below are features of thermoplastic resins:

Resin thermoplastik  mempunyai susunan molekul yang tidak menyilang yang menandakan bahan tersebut dapat dilelehkan dan digunakan kembali (dibentuk ulang). Biasanya tidak ada perubahan kimiawi ketika resin ini memadat. Resin thermoplastik biasanya dalam bentuk mimis padat dan berubah bentuk dengan penambahan panas dan tekanan. Berikut merupakan ciri-ciri resin thermoplastic :

Thermoplastic Resin

Pros
High Impact Strength
Attractive Surface Finish
Recyclable / Scrap is Reusable
No Emissions
Can bond to other thermoplastics
Can be molded or shaped with reheat

Cons
Generally softens with heat
More difficult to prototype

Common types of Thermoplastic Resins
Polyamide (PA or Nylon)
Polybutylene terephthalate (PBT)
Polyethylene terephthalate (PET)
Polycarbonate (PC)
Polyethylene (PE)
Polypropylene (PP)
Polyvinyl chloride (PVC)

and this all for my first class in "Composite and Polimer Manufacturing" hope it useful for everyone.

Thanks for reading

Destiny Inmato

Just want to tell all YuGiOh TCG fans my own original deck

I called it Destiny Inmato because it consist of destiny hero and plant type Inmato archetype. Inmato archetype is only consist of cherry inmato than can special summon up to 2 inmato monster and inmato that have atk 1400.

so this is my deck list

MONSTER

Destiny HERO Dogma                                 1x

Extra deck

any rank 4 XYZ (i put Utopia and Excalibur)
any Rank 3 XYZ ( use leviathan or acid golem for attacking and use zenmaines for deffending)
Synchro lvl 5 (i put catastor ) [coz cherry inmato can call inmato lvl 3 and cherry inmato (tuner) lvl 2]
Synchro lvl 6 ( use splendid rose coz i think it's a great beater in plan type using inmato in grave as cost)
Synchro lvl 7 (Blackrose dragon coz it have a great clearing field ability and can make any defend position monster atk become 0 by banishing 1 plant type monster in graveyard)
Synchro lvl 8 ( use 2 inmato and 1 cherry as material)
Synchro lvl 9 ( use 1 cherry 1 inmato and other lvl 4 as material)
E. hero Absolute Zero
E. Hero Great Tornado

-So this deck is designed for using ur opponent force to beat him. guard ur monster using Magic Cylinder and threatening roar than swap it with ur weak monster (usually cherry inmato coz after u beat it, two inmato will summoned and u can beat ur opponent with 2800 damage than in m2 u can xyz it to rank 3 xyz monster).
-Use diamond dude to mill Destiny draw to gain hand advantage.
- use miracle fusion to special summon E. Hero Absolute zero by using HERO monster and penguin soldier or rank 3 xyz such as leviathan or acid golem, u can also summon E.hero Great Tornado using Stratos and splendid rose or spore.
- use scapegoat or fires doomsday as ur guard or material for summoning E.hero Dogma or Plasma. Plasma can steal ur opponent monster (make it as equip and steal their ability). dogma can halved ur opponent life than u can just wait ur opponent dead by using Magic cylinder
-steal ur opponent monster using mark of the rose than xyz it or synchro it so it will not returnto ur opponent field.
- u can use summoner monk to throw any useless spellcard u don't need to summon stratos so u can return ur hand number than xyz it
- use avarice to return inmato in grave if u already wasted all inmato in deck .
other strategy can be used deppend on the monster ur steal and opponent style.

The biggest weakness in this deck is when u get all inmato in hand =_=" but u can just use it as a xyz material or banish it as a cost for allure of darkness

So that's all for my own original deck. have fun try it
