Some Natural or Synthetic Composite We didn't know 

Some of the naturally gifted composite -

1. Wood - In Wood, Cellulose is Reinforcement or Disperse Phase and Lignin is Matrix or Continuous phase.Cellulose in Lignin matrix as a fiber in a molecular level and Lignin is having a high molecular weight give a very strong Product. This composite having high load bearing capacity since its support high cantilever forces in the branches.

2. Animal Bone - It is Composite of Calcium hydroxyapatite (Ca10(OH)6PO4) as a Reinforcement and collagen as Matrix

Other Synthetic Composite

3.Roffing sheet - In this Composite Asbestose as fiber in disperse form and Cement as a matrix

4. RCC - It is well know Composite, Reinforcement Cement Concrete(RCC). Steel Rod and Stone chips are used as Reinforcement  while Cement,Sand and Water are as a matrix in composite.
