For normal fiberglass manufacturer, there are at least hundreds and thousands of sizing formulas they can use such as, filament winding, pultrusion, weaving, spray-up, hand lay-up, chopping, mat-use, SMC, BMC, transparent panel and so on. For a special resin and process method, there will be some modification on sizing recipe. A good sizing recipe can increase the performance up to 30% or even more. A special research and development team for the sizing is very important for a basalt fiber manufacturer. However, they can have their fiberglass partners as their reference so that so can save lost of time, energy and money for the sizing research. Normally, to get a mature sizing recipe from zero should cost a team with 5 or more persons more than 3 years and more than 100 million US dollars. Otherwise, it is smart for these basalt fiber manufacturer to learn from the fiberglass.
