  • Patent number: 7871701
    Abstract: An oriented strand board for structural applications and a method of its production comprising elongated strands having aspect ratios greater than 2, the strands being derived from the outer shells of oil palm tree fronds formed as a bi-product of the harvest of oil palm fruit, such that the strand length is limited to about a meter, the strands being cut from the outer shell area of the fronds and at least the outer regions of the major faces of the board being substantially free of core material, the shell strands being combined with a heat settable binder material, the strands being formed by elongated blades moving relative to a frond length in planes generally aligned with a longitudinal direction of the frond length, the strands of the frond shells being arranged and being permanently bonded together such that they are predominately generally aligned with the structural direction of the board at least at the outer regions of the major faces of the board.
