What Is The Hand Lay-Up Process?

What Is The Hand Lay-Up Process?

1.1. What Is The Hand Lay-Up Process? Hand Lay-up is fabrication process of FRP products (Fiber Reinforced Plastic). The FRP is composite material of Resin and Fiberglass strand or Fiberglass Mat. It involved building up layers of chopped glass or woven glass chopped strand mat impregnated with catalyzed resin around a suitable mould. The reinforcement is then rolled for better wet-out and removing trapped air.

1.2. Steps of Hand lay-up process Hand lay-up process is an open mold process. It is a simple process to manufacturing of FRP products Preparing Mold:- We take mold and removing any dust and dirt from mold. The mold material may be plaster, wood or new fiberglass, apply soft wax, P.V.A. and buff with soft towel.

· Applying Resin:- Resin is applied on mold by the brush. The brush is move like to painting of wall.

· Lay-up of Fiberglass:- Brush is applied of resin on mold then chopped fiber glass strands spread or chopped strand mat for hand lay-up over the resin layer

· Applying Resin:- Again apply the resin layer over the glass strand layer by using brush.

· Squeeze Action:- Second layer of resin is applied then roller is move over the layers of resin-fiberglass-resin, for removing the air between in layers. This action called squeeze action. This squeeze action also used for compact the product.

· Remold :- Lastly the sheet is removing from mold for hardening of sheet, the left in air at room temperature. And remold product is final of a corrugated fiber roofing sheet.We ask that authors follow some simple guidelines. In essence, we ask you to make your paper look exactly like this document.

FIBERGLASS VAN FLOOR KIT (including fiberglass chopped strand mat)

To make, lay, or laminate your own GRP van or truck floor it couldn’t be easier, all you need is a simple GRP fibreglass roof kit and these are sold with literally everything you need including tools, so it’s just a matter of measuring up your van floor and buying the correct size kit, simple. You may get a common choice of weight (thickness) i.e. 300g (1oz) or 450g (1.5oz), and either of these is absolutely fine.

If your looking to customise your requirements and want to buy your fibreglass in non kit form you will need to think about coverage, so here are the two most common weights of CSM and what coverage you can expect…

300g CSM fiberglass chopped strand mat requires approximately 1.5 litres of resin per square metre to cover.

450g requires 2 litres of resin per square metre.

Topcoat (colour or flowcoat) coverage is about half a litre per square metre.

CHOOSING THE RIGHT WEIGHT OF CSM (CHOPPED STRAND MAT) FIBREGLASS MATTING

(Article from Fixmyroof)

You may find all sorts of suggestions from fibreglass suppliers of what weight of fibreglass CSM (CHOPPED STRAND MAT) mat to use on your roof. Some don’t say, some say 450g, some 600g or others say double laminate 300g or 450g. In the end it turns into a “mines bigger then yours” contest devoid of all logic and reason. The simple truth is there are guessing because they want the best for you but they haven’t seen your roof, it’s size, it’s shape or how well it’s constructed. Some fibreglass suppliers are just suppliers and only that, and some have a history of fibreglassing roofs and can speak from real experience. Here are my suggestions, feel free to use them, ignore them, or improve on them.

  Small roofs – small garages, porches and bays 450g ( 1.5oz)

  Small garage sized roof’s – with foot traffic or medium to large roof 600g ( 2oz )

  Large roofs – i.e. > 50m2 single 600g or possible 450g double laminate for walkways.

  Large roofs – i.e. > 100m2 double 450g laminate

How to Choose the Resin

Resin selection can vary from fabric compatibility, service conditions, and desired characteristics of the finished part. There are generally three types of thermosetting resin to consider when approaching your project: Epoxy, Vinyl Ester, and Polyester. Let’s take a look at each of the choices, their characteristics, and what they should be used for.

1. Epoxy Resin

For composite parts that demand the ultimate strength, fabricators will use an Epoxy Resin. In addition to increased strength properties, epoxies also generally outperform polyester and vinyl ester for dimensional stability and increased bonding with other materials.

Pros: 

Epoxy Resin, High Strength Properties, Can be used in vacuum infusion applications, Easy to handle, Medium viscosity

Cons: 

Cannot be used with chopped strand mat

Not UV stable. This must be paired with a top coat when exposed to UV rays

2. Polyester Resins

Polyester Resins are the most widely used resins in the composites industry. Polyester Resins are less expensive, offer some corrosion resistance, and are more forgiving than epoxies. The majority of all fiberglass parts are constructed using Polyester Resins because they are easy to use, fast curing, and tolerant of temperature and catalyst extremes. Fibre Glast carries two different types of Polyester Resins, each with their own strengths and uses.

POLYESTER MOLDING RESIN

Pros:

Inexpensive, Easy to handle, Rapid wet-out, High thixotropic index (product won’t run on vertical surfaces)

Cons:

lower physical properties compared to more expensive resins

ISOPHTHALIC POLYESTER RESIN

Pros:

Dimensionally stable (minimal shrinkage), resists post cure problems, can be used in food contact applications

Cons:

Slightly more expensive than general purpose polyester resins

3. Vinyl Ester Resin

Vinyl Ester Resin is considered a hybrid of polyester and epoxy—meaning its handling characteristics, properties, and price generally fall just between the other two. It is important to note that, Of the three, vinyl ester resin will provide the highest corrosion resistance, temperature resistance and elongation (toughness.) Because of this, they are typically used when high durability, thermal stability, and corrosion resistance is needed.

Pros:

Vinyl Ester Resin, Extremely tough, corrosion resistant, heat resistant

Cons:

Short shelf life (3 months)
