摘要

The suitability of rattan canes as structural material for appropriate utilization is demonstrated by its properties. Thus, in order to satisfactorily use the canes of rattan as a raw-material for structural purpose, the properties must be studied. This study therefore investigated the density and some strength properties of Laccosperma secundiflorum from two different ecological zones. Three matured wild Laccosperma secundiflorum were obtained each from fresh water swamp and Rain forest. Samples were collected along the sampling height: base, middle and top. Density and selected strength properties test; Modulus of Rupture (MOR), Modulus of Elasticity (MOE) and Maximum Compressive Strength Parallel to Grain (MCS//) were carried out on the L. secundiflorum samples from the two ecological zones and data were analysed using descriptive statistics and ANOVA at P<0.05. From the results, density ranged from 407.21±55.65 to 485.39±32.25kg/m3. MOR and MOE varied from 41.75±3.88 to 57.39±4.17N/mm2; 438.50±48.14 to 711.34±249.02N/mm2 respectively. While, MCS// increased from 24.72±1.50 to 34.15±1.90N/mm2. Results further showed that density and strength properties decrease along the axial direction from base to top. While, the samples of L. secundiflorum sourced from rain forest had higher density and strength properties values compared to samples from fresh water swamp. Based on the result obtained, L. secundiflorumsamples obtained the base and from rain forest were denser and the strongest in terms of strength.
