AB  - Composites of unsaturated polyester resin (UPR) and cellulose nanofibers (CNFs) 
      obtained from dry cellulose waste of softwood (Pinus sp.) and hardwood 
      (Eucalyptus sp.) were developed. The fiber properties and the influence of the 
      CNFs in the dynamic-mechanical and thermomechanical properties of the composites 
      were evaluated. CNFs with a diameter of 70-90 nm were obtained. Eucalyptus sp. 
      has higher alpha-cellulose content than Pinus sp. fibers. The crystallinity of the 
      cellulose pulps decreased after grinding. However, high values were still 
      obtained. The chemical composition of the fibers was not significantly altered by 
      the grinding process. Eucalyptus sp. CNF composites had water absorption close to 
      the neat resin at 1 wt% filler. The dynamic-mechanical properties of Eucalyptus 
      sp. CNFs were slightly increased and the thermal stability was improved.
