These statement are true about wet layup EXCEPT..

I. Most common and basic techniques in composite

process.

II. It is cheap, labor intensives and most versatile for the

product that do not require high precision and high

properties.

III. Curing techniques by autoclave cure

IV. Theses processes can be applied on a small product such as water tank up to big scale product as leisure yard.

MEKP stands for

The spray-up process is approximately similar to hand lay-up method EXCEPT

Cleaning the uncured polyester resin from brushes and tools can be done using acetone

It has advantages of having greater strength and adhesion, strong adhesion to hardwood, metal and glass, lower shrinkage and chemical resistance . This statement is referring to

First step when working in open mold is application of release material to the mold. This statement is referring to...

I. Wax

II. PVA

III. Gelcoat

IV. Release papers and release films

The resin to glass ratio is to about 1:2

Spray Up equipment are available in three (3) types.

The “green” stage is where the laminate is fully cured, and the trimming process at the edges is advisable to be done at this stage.

The advantages of using open hand lay-up and spray up process are as below statement EXCEPT

If practice the wet laminating hand lay-up process to fabricated the product, which fiber appropriate to used.

I. Roving

II. CSM 300

III. CSM 450

IV. Woven Roving 600

Calculate the total surface area for that product

How many fiber CSM 300 will be used to produce the products through hand lay-up process referring to below diagram.

How many fiber WR 600 will be used to produce the products through hand lay-up process referring to below diagram

Release agent act as a?

Fiber glass is expensive than carbon fiber.

Resin will hot and gel suddently if we add MEKP too much

Resin will gel like usual without MEKP added

Referring to below diagram, calculate the total surface area for that product.
