Pre-Mix And Mixing Notes
Prepare all needed tooling and materials before mixing the resin and curing agent together.
Pour the desired amount of resin then the curing agent in a clean container and gently mix with a spatula or mixing blade until a uniform blend is achieved.
Scrape the sides and bottom of the container to ensure a thorough mix.
Pour or apply the resin directly onto the prepared surface and allow to cure for at least 24 to 36 hours.
The mixed resin will set-up in less than 2 hours and can be handled in 3 hours.

Weaves:
Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction.
PLAIN WEAVE Is a very simple weave pattern and the most common style. The warp and fill yarns are interlaced over and under each other in alternating fashion. Plain weave provides good stability, porosity and the least yarn slippage for a given yarn count. |
8 HARNESS SATIN WEAVE The eight-harness satin is similar to the four-harness satin except that one filling yarn floats over seven warp yarns and under one. This is a very pliable weave and is used for forming over curved surfaces . |
4 HARNESS SATIN WEAVE The four-harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern, there is a three by one interfacing where a filling yarn floats over three warp yarns and under one. |
2x2 TWILL WEAVE Twill weave is more pliable than the plain weave and has better drivability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns. |

Step Three:
Proper Lay-Up Technique -Putting It All Together
Pre-lay-up notes
Mix the proper amount of resin needed and be accurate proportioning the resin and curing agent. Adding more curing agent than the recommended mix ratio will not promote a faster cure. Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance. When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin. If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage.
Don’t how much resin to use to go with the fiberglass?
A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight. This is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application. For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor. This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY (ounces per square yard) or GSM ( grams per meter square ) data.
THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED

Typical fabric weight regardless of weave pattern
1 ounce per square yard is equal to 28.35 grams
1 square yard equals to 1296 square inches (36 inches x 36 inches)
FOR EXAMPLE
1 yard of 8-ounces per square yard (OSY) fabric weighs 226 grams
1 yard of 10-ounces per square yard (OSY) fabric weighs 283 grams
Ounces per square yard or OSY is also known as aerial weight, which is the most common unit of measurement for composite fabrics. To determine how much resin is needed to adequately impregnate the fiberglass, use the following equation:
(Total Weight of Fabric divided by 60%)X( 40%)= weight of mixed resin needed
OR
fw= fabric weight
rc= target resin content
rn=resin needed
MASTER EQUATION
(fw/60%)x(40%)=rn
FOR EXAMPLE
1 SQUARE YARD OF 8-OSY FIBERGLASS FABRIC WEIGHS 226 GRAMS
(226 grams of dry fiberglass / 60%) X 40% = 150.66 grams of resin needed
So for every square yard of 8-ounce fabric, it will need 150.66 grams of mixed resin.
Computing For Resin And Curing Agent Amount
150.66 grams of resin needed
MIX RATIO OF RESIN SYSTEM IS 2:1 OR
50 PHR (per hundred resin)
2 = 66.67% (2/3)
+
1 = 33.33%(1/3)
=
(2+1)=3 or (66.67%+33.33%)=100% or (2/3+1/3)= 3/3
150.66 x 66.67%= 100.45 grams of Part A RESIN
150.66 x 33.33%= 50.21 grams of Part B CURING AGENT
100.45 + 50.21 = 150.66 A/B MIXTURE
GENERAL LAY-UP PROCEDURE
Apply the mixed resin onto the surface and then lay the fabric and allow the resin to saturate through the fabric.
NOT THE OTHER WAY AROUND
This is one of the most common processing error that yields sub-standard laminates. By laying the fiberglass onto a layer of the prepared resin, less air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles. This technique will displace air pockets unhindered and uniformly disperse the impregnating resin throughout the fiberglass.

VACUUM BAGGING PROCESSVideo will open in a new window
Similar to the Vacuum Bagging Process where the negative pressure is used to apply consolidation force to the laminate while the resin cures, the resin is infused into the fabric lay-up by sucking the impregnating resin and thus forming the composite laminate.
The VARTM Process produces parts that require less secondary steps, such as trimming, polishing or grinding with excellent mechanical properties. However, the vacuum infusion requires more additional or supplemental related equipment and expendable materials. So the pros and cons of each presented composite fabrication process should be carefully determined to suit the user's capabilities and needs.
