The heat resistance of MAX 1618 A/B was tested by heating a 2-inch cube in 5-degree increments and the Shore hardness was determined using both the Shore A and D scale.
This test demonstrates the heat resistance of the MAX 1618 A/B by determining at what temperature the Shore Hardness reading dramatically change.
At 140 °F, a considerable change in Shore D Hardness Scale occurred due to the sharp needle-like indenter of the equipment began puncturing the surface of the specimen which may make the Scale D Hardness an unreliable test data.
The Shore A scale demonstrated a dramatic change in hardness at 240°F which demonstrates it maximum heat tolerance more accurately than the Shore D scale.

Shore hardness is a measure of the resistance of a material to penetration of a spring-loaded needle-like indenter.
Shore A scale is used for testing soft elastomers (rubbers) and other soft polymers.
The hardness of hard elastomers and most other polymer materials is measured by Shore D scale.
Shore hardness is tested with an instrument called Durometer.
Durometer utilizes an indenter loaded by a calibrated spring.
The measured hardness is determined by the penetration depth of the indenter under the load.
Two different indenter shapes and two different spring loads are used for two Shore scales (A and D).

The Proper Cure And Final Performance Of Any Epoxy Resin System Are Highly Dependent On The Quality And Thoroughness Of The Mix.
The Resin And Curing Agent Must Be Mixed To Homogeneous Consistency.
PROPER MIXING TECHNIQUE
MAX 1618 A/B works well as an impregnating resin for carbon fiber, fiberglass, aramids or Kevlar, and other composites fabrics.
Its low mixed viscosity and long working time make it an ideal resin for vacuum infusion and hand lay-up process.
General Principle Of Vacuum Bagging
20 Layers Carbon Fiber Vacuum Cured Laminate
By resolute definition, a fabricated COMPOSITE material is a manufactured collection of two or more ingredients or products intentionally combined to form a new homogeneous material that is defined by its performance that should uniquely greater than the sum of its individual parts.
This method is also defined as a SYNERGISTIC COMPOSITION.

COMPOSITE LAMINATE WITH THE BEST WEIGHT TO STRENGTH PERFORMANCE
With respect to the raw materials selection -fabric and resin, the fabricating process and the and curing and test validation of composite part, these aspects must be carefully considered and in the engineering phase of the composite.
TYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHING
FOR RESIN TYPE COMPATIBILITY
Fabrics are generally considered ”balanced” if the breaking strength is within 15% warp to fill and are best in bias applications on lightweight structures.
“Unbalanced” fabrics are excellent when a greater load is required one direction and a lesser load in the perpendicular direction.
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.
All of our fiberglass fabrics is woven By HEXCEL COMPOSITES, a leading manufacturer of composite materials engineered for high-performance applications in marine, aerospace for commercial and military, automotive, sporting goods and other application-critical performance.
These fabrics are 100% epoxy-compatible and will yield the best mechanical properties when properly fabricated.

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.
Eliminating air entrapment or void porosity in an epoxy/fiberglass lay-up process
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.
Please view the following video demonstration which explains the process of Vacuum Infusion or VARTM process.

Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system.
The container in which the epoxy and curing agent is mixed is an important consideration when mixing an epoxy resin system.
The container must withstand the tenacity of the chemical and must be free of contamination.
Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
