Fiberglass DBM 1808 Knytex Biaxial +/- 90 Degree Fabric 50"/127cm 18oz/610gsm DISCOUNTED REMNANTS

Unit of Measure:

Fiberglass DBM 1808 Knytex Biaxial Fabric 50" Width. This material is great for quick buildup and high strength projects. This material contains 18oz fiberglass woven at 90 degrees. On the backside a layer of 3/4oz fiberglass mat is also attached. This material offers strength in various directions and is great for many projects. Thickness is .048". This material was made in the USA by Knytex, a respected manufacturer in the composite industry, and will ensure you receive quality material.

To harden this material you will need to use one of our Epoxies or Resins. This fiberglass is compatible with polyester, vinyl ester and epoxy resins.

First Quality Remnants:

                First Quality Fabric Remnant Rolls are short rolls of fabric, which have no defects in them.  These remnant rolls are either left over fabric from the end of a roll, or sections of fabric which were cut at the wrong length for a specific order.  So instead of discarding the short roll, we package it up and sell it as a First Quality Remnant Roll.  These First Quality Remnant Rolls are sold at 20% off of the retail price of that fabric.


Second Quality Remnants:

                Second Quality Fabric Remnant Rolls are short rolls of fabric, which have a defect in the woven fabric in them.  These remnant rolls are cut out of the standard fabrics we sell, but from sections of the rolls that have some defects in them.  These defects make them not good to use if you want to make cosmetic parts, which have perfect woven fabric in them, but can be used as the inner layers of your parts, or if you are making small parts and can cut around the defects.  These Second Quality Remnant Rolls are sold at 25% off of the retail price of that fabric.  

                All remnant rolls are rounded DOWN to the nearest ½ yard. So a remnant listed as 0.5 yards may actually be between 18” and 35” in length and a remnant listed at 2.0 yards may actually be between 72” and 89” in length.

The resin consumption provided is for the approximate amount of resin by weight, contained in the final part after processing by vacuum infusion. This does not account for the resin used in the flow lines and consumables such as flow media or breather cloth. Wet-layup by hand will also have a higher resin consumption in the final part and is dependent upon users techniques. Vacuum bagging a wet layup will improve the resin content. Too much resin will cause a weaker part, NOT stronger. Average rule of thumb is around 45% (+/- a couple percent). To calculate actual resin % in your part a burn test is used. For example you have a part weighing 100 grams, you would burn off the resin which would leave the fiber behind. You should have 55 grams of fiber left when your process is working correctly. Due to the variables in processing it is hard to give an accurate amount of resin needed to purchase for making your part. However you will have waste no matter what method is used. A suggested ratio is about 1-1.5lbs of resin per lb of fabric purchased.
