Method for pore sealing a porous substrate, comprising: forming a continuous monolayer of a polyimide precursor on a liquid surface, transferring said polyimide precursor monolayer onto the porous substrate with the Langmuir-Blodgett technique, and imidization of the transferred polyimide precursor monolayers, thereby forming a polyimide sealing layer on the porous substrate. Porous substrate having at least one surface on which a sealing layer is provided to seal pores of the substrate, wherein the sealing layer is a polyimide having a thickness of a few monolayers and wherein there is no penetration of the polyimide into the pores.

A flexible coupling for transmitting torque between parts of a transmission shaft system comprises a tubular section of continuous-fibre-reinforced composite material which has been modified to form a living hinge section with reduced bending stiffness to allow flexion of the tubular section. The tubular section may be modified through the provision of a pattern of formations within the living hinge section. The formations may be in the form of apertures and/or recesses in the continuous-fibre-reinforced composite material to create a plurality of living hinges in the material between, in particular slots and/or grooves.

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.

An anisotropic conductive film 1A includes a conductive particle array layer 4 in which a plurality of conductive particles 2 are arrayed in a prescribed manner and held in an insulating resin layer The anisotropic conductive film 1A has a direction in which a thick distribution, around the individual conductive particle, of the insulating resin layer 3 holding the array of the conductive particles 2 is asymmetric with respect to the conductive particle 2. The direction in which the thickness distribution is asymmetric is aligned in the same direction in the plurality of conductive particles. When an electronic component is mounted using this anisotropic conductive film 1A, short circuits and conductive failure can be reduced.
