Bamboo Fibre Mat Board/Bamboo Mat Board

Bamboo mat boards (BMB) are produced from woven mats of bamboo that are soaked in adhesive resin and then pressed firmly together in a hot press. They were the first of the wide range of different panel boards presently available that use bamboo as a raw material, but they are the simplest to produce, involve only bamboo raw materials and have great income generating potential for the rural poor, who are able to weave the mats from which they are formed. The technology for the manufacture of BMB in India has been developed by the Indian Plywood Industries Research Institute (IPIRTI), Bangalore, who have developed a technically feasible and commercially viable technology for its manufacture. BMB is gaining in popularity and there are currently a handful of BMB factories in operation in India and 16 in China.

Bamboo mat board is very versatile and can be produced up to 6 mm thick by varying the number of mat layers used; boards are usually formed of 2, 3, 5 or 7 mats. For thicker laminated boards, wood veneers are interleaved with the bamboo boards to produce bamboo mat-veneer composite boards (the production of these is not covered in this TOTEM). BMB is at least as durable and stable as wood-based plywood and is very resistant to pest attack, extreme climatic conditions and fire. It can be used for many of the uses to which plywood is now put such as paneling, ceilings, prefabricated shelters, packing cases and storage bins, roofs, doors and door panels, furniture, and household utensils such as trays and plates. BMB is much more flexible than wood-based-plywood and can be used in structural applications such as stressed skin panels, wall bracings and web beams for which plywood is not suitable.

The first recorded production of bamboo based panels was in China during the mid 1940s where bamboo mat board bonded with casein (enamel) glues was used in the interior of aeroplanes as an alternative to aircraft-grade plywood. At about the same time research was initiated in India to develop synthetic resinbonded bamboo mat board, for which the technology became available a decade and a half later. Since then, research has been carried out in several countries and over 30 types of panel products have been developed-some made of bamboo only and others of bamboo in combination with wood, lignocellulosic materials and inorganic materials. Research and development efforts have been mostly confined to countries of the AsiaPacific region i.e. China, India, Indonesia, Japan, Laos, Malaysia, Philippines, Taiwan, Thailand and Vietnam. Canada (in collaboration with Costa Rica) is the only country outside Asia where research on bamboo panels is being carried out.

The invention provides for this purpose a method for manufacturing a bamboo mat, comprising the processing steps of

  • A) processing bamboo into bamboo strips,
  • B) drying the bamboo strips to a predetermined moisture content,
  • C) machining at least the longitudinal sides of the bamboo strips dried according to step B) so as to form a uniform plane,
  • D) parallel positioning of a plurality of machined bamboo strips with the longitudinal sides adjoining, and
  • E) mutually connecting the parallel positioned bamboo strips by means of coupling means.

Although there was some pioneering work in Taiwan and innovative products such as plybamboo (bamboo glue-lam) were developed, the bamboo board industry is reported to be facing extinction there due to the sharp increase in wages and shortages of raw materials. In Thailand, the only product manufactured is bamboo mat board glued with Urea Formaldehyde (UF) resin and this is mainly produced for export. In countries such as Laos, the Philippines and Vietnam, interest in bamboo matboard production is relatively new, and the industries there are presently in the phase of exploratory studies and experimental or pilot scale production.
