The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).

G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. [1] It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures.
The data of this table is from best cases, and has been established for giving a rough figure. Note: Multiwalled carbon nanotubes have the highest tensile strength of any material yet measured, with labs producing them at a tensile strength of 63 GPa, [ 36 ] still well below their theoretical limit of 300 GPa.

Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

SU-8 is a commonly used epoxy-based negative photoresist. Negative refers to a photoresist whereby the parts exposed to UV become cross-linked, while the remainder of the film remains soluble and can be washed away during development. As shown in the structural diagram, SU-8 derives its name from the presence of 8 epoxy groups.
Start by applying the epoxy to the fiberglass sheet. Continue carefully but quickly until all areas are sufficiently covered by the epoxy. Next, start at one end of the material to be strengthened and stick the epoxy covered fiberglass to the material, being sure to smooth out any bubbles that may form between the material and fiberglass.
