The present teachings contemplate a method comprising providing a first and second substrate, locating an initiator onto a surface of the first or second substrate, the initiator including a substance for initiating polymerization of a polymerizable adhesive, locating the polymerizable adhesive onto a surface of the first and second substrate, the adhesive including a monofunctional, difunctional, or multifunctional methylene malonate, or cyanoacrylate, and contacting first and second substrate.

A thermosetting resin composition contains a thermosetting resin and an inorganic filler. The thermosetting resin includes a curing agent. A 3 mass % methyl ethyl ketone solution of the curing agent has a Gardner color scale of 15 or more. The content of the curing agent accounts for 10 mass % or more of a total solid content of the thermosetting resin composition.

A filler-containing film has a structure in which fillers are held in a binder resin layer. The average particle diameter of the fillers is 1 to 50 μm, the total thickness of the resin layer is 0.5 times or more and 2 times or less the average particle diameter of the fillers, and the ratio Lq/Lp of, relative to the minimum inter-filler distance Lp at one end of the filler-containing film in a long-side direction, a minimum inter-filler distance Lq at the other end at least 5 m away from the one end in the film long-side direction is 1.2 or less. The fillers are preferably arranged in a lattice form.

The present invention relates to a process for preparing a bonding resin, wherein a resin prepared from lignin, phenol and formaldehyde and comprising a formaldehyde scavenger, is mixed with a resin prepared from phenol and formaldehyde and comprising a formaldehyde scavenger to achieve a mixture useful as a bonding resin useful in the manufacture of oriented strand board (OSB).

A phenolic resin foam has a density of 30 kg/m.sup.3 to 80 kg/m.sup.3, a closed cell ratio of 85% or more, and reaches a total amount of heat release of 8 MJ/m.sup.2 in a time of 20 minutes or more in a heat release test performed using a cone calorimeter.

A drum for a roller compactor has an outer shell providing an exterior peripheral compacting surface and an interior for housing an excitation system used to vibrate the drum. The outer shell includes a non-elastic polymer with embedded reinforcing fibers.

This invention relates to a method for manufacturing a mineral wool board, comprising the following steps in the given order: providing mineral wool fibers having a fiber length of 50 to 800 m; gluing the fibers with a liquid binder comprising phenolic resin, whereby the ratio of binder (based on the solids content of the resin of the binder) to mineral wool fibers is 5 to 30% by weight, and pressing the glued fibers using heat and pressure.

A prepreg including: a woven cloth substrate; and a semi-cured product of a resin composition. The resin composition contains: at least one of an (A1) component and an (A2) component, a (B) component; a (C1) component; and a (C2) component. The (A1) component is an epoxy resin having at least one of a naphthalene skeleton and a biphenyl skeleton. The (A2) component is a phenol resin having at least one of a naphthalene skeleton and a biphenyl skeleton. The (B) component is a high molecular weight polymer. The (C1) component is a first filler obtained by treating surfaces of a first inorganic filler with a first silane coupling agent represented by formula (c1). The (C2) component is a second filler obtained by treating surfaces of a second inorganic filler with a second silane coupling agent represented by formula (c2). ##STR00001##

The present disclosure provides composites comprising an open cell foam and a small pore area material, methods for their preparation, articles of manufacture comprising them and methods for preparing the same.

Processing fiber-reinforced composite to recover continuous reinforcing fibers in a continuous form. The processing includes first treating the composite with a normally-liquid first solvent for material of the matrix followed by removal of the first solvent from the first solid residue including reinforcing fibers. The removal of the first solvent from the continuous reinforcing fibers may heating the fibers and/or second treating the first solid residue with a normally-gaseous material contacted with the solid residue under conditions of temperature and pressure at which the normally-gaseous material is in a liquid or supercritical fluid form. The processing may be performed in a continuous manner to recover the continuous reinforcing fibers in a continuous form.
