The present research work had as objective to elaborate and to evaluate the optimal agglomerate board based on fiber and endocarp of coconut (Cocos nucifera) and cement, according to its physical-mechanical properties like resistance to the flexion (kg/cm2), density (g/cm3), swelling (%vol.) and water absorption (%weight), where these values were compared with the standardized measures of the FAO for agglomerate boards of medium density. The experimental methodology consisted of three phases; the first one is the obtention of coconut fiber and endocarp in the District of Pucacaca - Province of Picota to be later submitted to an extraction and retting process, the second phase is the elaboration of agglomerated boards according to relations (1: 2, 2:1, 1:3, 3:1) of fiber-endocarp/cement in proportions of 40, 50 and 60%, and the third phase in the mechanical and physical evaluation of the boards that were made according to the specifications of the Peruvian Technical Norms of Wood. A Completely Random Design (CRD) with 12 treatments and 3 repetitions was used to respond to the objectives set through an analysis of variance (ANOVA) and Tukey's test at a probability of α=0.05. The obtained results were: that, from the experiments developed on agglomerated boards, the best mixtures according to their physical-mechanical properties were 10% fiber - 30% endocarp and 60% cement that belong to the evaluated sample T9, unlike the sample T10 of mixture 45% fiber - 15% endocarp and 40% cement. Only the T3 samples (190,880 kg/cm2, 0.67 g/cm3, 7.749%vol., 69.283% weight); and T8 (141,387 kg/cm2, 0.65g/cm3, 9.243%vol., 73.806% weight) met the standards established by FAO for their commercialization. In conclusion, the optimal medium density chipboard that had better response according to elaboration and evaluation was the sample T3 (13.3% fiber - 26.7% endocarp and 60% cement), and that statistically presented a highly significant difference (Sig.=0.000<0.05) of the studied chipboards. In addition, it was verified that the increase in the percentage of fiber in the cement generates a decrease in the resistance and an increase in water absorption and moisture movements.
