INTRODUCTIONWith dwindling forest resource of the world there is growing awareness for usingproducts more efficiently. Wood scientists and technologists are continually seeking waysto develop technologies which will ensure that the products made closely match therequirements of the users. This requires process improvements in characterizing raw,material, in developments of products and in the evaluation of manufactured products.Here we provide an example where we have made use of electron microscopy,techniques to more precisely understand the nature of the relationship between themicrodistribution of middle lamella lignin in rubberwood cells and the surfacecharacteristics of the MDF fibers produced fiom this wood.Interest in the manufacture and use of fiber-based products is growing rapidly,because fibers can be manipulated more easily than the solid wood. thus enhancing ourcapability for a better control and monitoring of processes and to produce a wider rangeof products (reviewed in Singh and McDonald 2000).Additionally, fiber-based productscan be more easily and precisely tailored to suite market requirements. The use offibers also provides opportunities for using a mix of both natural and synthetic fibers inproduct formation, and thus to help reduce the ever increasing pressure for use of theworlds wood resourge.By an example of the MDF fibers, in this communicarion we examine theimportance of using transmission electron microscopy in understanding the relationshipbetween the pattern of middle lamella lignin distribution in unprocessed wood andsurface features of the MDF fibers.-14-:-:::i:i- :i::*-s lF,
