Our aim was to develop means to produce purified cellulose cell wall fragments and cellulose microfibrils from primary cellular material at laboratory scale, to form novel composite materials with a range of matrix binders and to determine their tens

The mechanical properties of a composite manufactured from bovine tendon and pearl glue (an animal glue containing gelatine and other proteins) are investigated. This composite was traditionally used in the construction of Asiatic re-curve bows for a

Hemp grown for fibre production is normally retted to allow the separation of the fibre from the core tissue of the stem. Retting requires stems to be exposed in field for several weeks, and both retting and subsequent drying are weather-dependent. I

The usefulness of unretted hemp as a source of fibre for composite manufacture is investigated. A decortication machine was used to remove fibre from retted and unretted stems using two different decortication procedures, defined as ‘normal’ and

Genetically modified tobacco plants ( Nicotiana tabacum ‘Samsun’) with antisense cinnamyl alcohol dehydrogenase DNA, produce secondary xylem of a reduced tensile stiffness. These plants were grown alongside control plants. The stems of the plants

Tobacco plants (Nicotiana tabacum‘Samsun’) have been grown with an antisense CAD (cinnamyl alcohol dehydrogenase) gene. This modifies lignin production, resulting in lignin with a greater aldehyde content which is easier to extract chemically. Th

Lignin in the cell walls of woody tissue has a much lower crosslink density in tobacco wood than in tree wood. This causes tobacco wood to show very different viscoelastic behaviour. With the aid of genetically modified plants, it is shown that the l

The egg capsules of dogfish are largely constructed from laminae of parallel orientated collagenous fibrils arranged longitudinally, near-diagonally, and near-transversely. The fibrils show an axial (D) period of about 40 nm. These characteristics fa

Plant fibres are gaining acceptance as glass fibre replacements in composite manufacture. Currently only long vegetable fibres from plants like hemp and flax are used. However, all plant cells, including those that are not elongated, have the potenti
