#Composites
<blockquote>Composites are materials that combine two or more components. Fibers for stiffness, and a matrix for support. Together they make a ply. Fibers can be uni-directional, woven or chopped.</blockquote>

## [Composite manufacturing](https://www.twi-global.com/technical-knowledge/faqs/faq-how-are-composites-manufactured/)
###Wet Lay-up
Resis in apply, often with rollers, to layers of fiber.
###Spray-up
Chopped fiber is mixed with resin and sprayed to make the desired thickness laminant.
