“…The shear strength depends on the strength of the adherent materials wood and adhesive, on the stress distribution within the glue line and on the ability of the adhesive to transfer the acting stress into the glue line and thus from one adherent surface to the other (Steiger;Arnold;Risi, 2014). The literature reports MOR values ranging from 49.25 to 83.33 MPa for glued laminated beams produced with rubberwood (Nadir;Nagarajan, 2014;Parra-Serrano et al, 2018). The wood treated with CCA and CCB showed the lower values for MOR and this strength loss can reach up to 20% depending on the product retention and severity of the drying temperature applied as American Wood Protection Association -AWPA (2016).…”

“…In the last decades, this raw material has become important for the manufacture of furniture, due to the attractive coloring and density of the material (Teoh et al, 2011). In the panel segment, rubber tree wood has been used in the production of cement-wood composites (Iwakiri et al, 2017), LVL panels (Faria et al, 2020), particulate panels (Iwakiri et al, 2018;Lamaming et al, 2020) and glued laminated timber (GLT) beams (Nadir et al, 2016;Parra-Serrano et al, 2018;Faria et al, 2019).…”

This work aimed to evaluate the physical and mechanical behavior of glued laminated timber (GLT) - glulam pieces of Hevea brasiliensis treated with chromed copper arsenate (CCA), chromed copper borate (CCB) and pyrethroid in the production of GLT. The pieces were produced using three wooden laminae with dimensions of 60 x 20 x 1200 mm, (width x thickness x length), joined with epoxy adhesive under 1.0 MPa pressure for 24h at room temperature. The rubberwood had an apparent density of 0.624 g cm-3, a value close to that of Eucalyptus grandis wood, a species traditionally used in the manufacture of GLT. Regarding the GLT parts, it was observed that the preservative treatment with CCA and CCB influenced negatively the values of the mechanical properties. For resistance modulus (MOR), a reduction of 75.44 MPa to 62.36 and 58.57 MPa was found for the parts untreated and treated with CCA and CCB, respectively. There was no statistical difference for surface treatment with pyrethroid. The photomicrographs of the glue line showed that the reduction in these values was mainly due to the penetration of preservative solutions into the wood structure (cell lumens and vessels or pores), impairing the anchoring of the adhesive.

“…Rubber processing waste has been studied as a source of protein and bio-fertilizer (Iewkittayakorn et al, 2018;Tahir and Misran, 2019). Rubberwood can be processed as a substitute for forest wood (Arsad, 2009;Parra-Serrano et al, 2018). Other parts of the plant, such as leaves and roots, can be processed into biomass.…”

THE ANCILLARY PRODUCTS OF RUBBER (Hevea brasiliensis Muell. Arg.): POTENTIAL RESOURCES TO ENHANCE SUSTAINABILITY

Indonesia is one of the major natural rubber-producing countries. The low rubber prices severely affect rubber agribusiness as farmers and rubber companies depend on latex as the only source of income. This condition leads to an unprecedented challenge to rubber agribusiness sustainability. This systematic review aims to encourage the use of part of rubber plants as a source of revenue for rubber plantations to maintain their sustainability. Non-latex parts of the rubber plant can be utilized, including latex serum and skim waste, parts of rubber seeds, and rubberwood. The strength of the ancillary product of <em>Hevea brasiliensis </em>is that the raw materials are abundant, yet the weakness is that the rubber companies have no experience exploiting them. The opportunity for utilizing is widely open, as many methods have been researched; however, the main thread is how to compete with the existing products. Therefore, careful market research and feasibility studies are recommended.

“…Hal ini disebabkan ketidaksempurnaan dalam peletakan dan pelaksanaan finger joint yang memiliki kecenderungan sebagai titik inisiasi kegagalan pada balok glulam. Namun demikian, proses laminasi yang baik tetap memungkinkan kayu Karet dapat memenuhi ketentuan struktural (Parra-Serrano et al, 2018). Dengan melalui proses laminasi, produksi glulam yang lebih homogen dapat dicapai karena cacat kayu dan ketidaksempurnaan kayu dapat didistribusikan secara acak pada balok.…”

This study is aimed to determine the flexural behavior of Rubberwood FJLB (finger jointed laminated board) beams as building structural components. It was carried out through experimental approach and numerical analysis on six specimens of FJLB beams having a cross-section of 100 mm by 150 mm and a length of 2850 mm. The experiment was consisted of small specimen tests (BS-373:1957) and four-point bending test (EN-408) with two different cross-sectional orientations (flatwise and edgewise). The numerical analysis was performed by conducting 2-D finite element analysis developed in MATLAB program based on plane stress assumption. It was found that the average flexural capacity of beams tested under edgewise orientation was 24.6 kN, which is higher than that of the beams tested under flatwise orientation, 19.7 kN. However, the flexural stress (modulus of rupture) of those beams was about the same. All the beams experienced brittle failure caused by glueline failure between laminas or at finger joints. The results of strain measurement at mid-span of the beams throughout the test showed that the FJLB beams failed within elastic response. This finding was confirmed by the numerical analysis results.
