Over the past decade carbon fiber technology has greatly expanded thanks to new more streamlined manufacturing processes.
Vinyl ester versus epoxy resin.
The b side is typically the hardener side.
Using epoxy you can improve the laminate properties with a post cure almost always.
Vinylester resin as was explained to me by an r d chemist named mike daniels.
High density cross linked products are suitable for temperatures above 250 o f 121 o c.
Mike works for a huge minnesota company and he does know his chemistry.
Standard epoxy vinyl ester resins are limited to 220 250 o f 104 121 o c in most applications.
Differences between resins there are three main types of resins used for composite materials.
Here s a different way to look at epoxy resin vs.
Vinylester is essentially a styrene modified epoxy resin.
Polyester resins are standard resin for composite construction.
To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.
These new methods create automotive and motorcycle parts which are stronger and more impact resistant than steel and weigh 1 4th less.
Choosing the appropriate resin epoxy vs.

It adds excellent strength rigidity adhesion water and chemical resistance.
The resin side is typically designated as the a side.
Our epoxy comes in either a 2 1 or 4 1 ratio.
Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
Epoxy adheres to wood much better than polyester does.
Specifically proper cure of vinyl ester resins and a 15 year study of the effective use of permeation barriers in marine composites to prevent corrosion and blistering.
One of the only downsides to epoxy is that it is more expensive than polyester and vinyl ester resin.
Because of their chemical structure vinyl esters and epoxies offer higher mechanical strength adhesion and heat resistance over polyester resins.
Has some great papers on this which i am quoting from.
Vinyl esters also use peroxides e g.
Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance.
Cloth and polyester resin.
Plus he has 25 years of making all kinds of cool stuff and is an expert wood crafter.
Epoxy resin comes in two parts.
