    Furthermore, pulp beating increases the durability of composites, as proven by Tonoli et al. , due to the improved surface contact area after refining, which enhances the adhesion of the sort fibers to the matrix. Refining is carried out through a disc refiner with a relatively narrow gap between rotor and stator.
