An amorphous structure layer is formed on a surface layer of a bonded portion of each of side brackets. A bottomed hole layer including a plurality of bottomed holes is formed on a surface layer of the amorphous structure layer. Each of the bottomed holes has a reverse-tapered shape, which has, between an opening portion and a bottom portion of each of the bottomed holes, a bulged portion having a larger inner circumference than the opening portion. An adhesive is injected into the bottomed holes. An outer circumferential surface of the bonded portion of each of the side brackets and an inner circumferential surface of an end portion of a center beam face toward each other with the adhesive interposed therebetween.

A bulletproof protection structure comprises at least a flexible base and a reinforcing structure realized by means of at least one ballistic panel associated with the flexible base. The ballistic panel is finely divided into a plurality of elementary components, individually associated with the flexible base, structurally independent of one another and not bound to each other, so as to ensure flexibility for the structure as a whole.

There is provided an article having at least a first surface having: a binder resin layer comprising an actinic radiation reactive polyurethane dispersion, where the binder resin layer has a first major surface opposite a second major surface; and a plurality of microspheres partially embedded and adhered to the first major surface of the binder resin layer. There is also provided a thermoset article derived from such thermoformable articles.

In an manufacturing apparatus, a belt-shaped electrolyte polymer is conveyed in a state disposed to a back sheet. A first reinforcement membrane is conveyed in a state disposed to a back sheet, and, in a first sticking section, stuck with the belt-shaped electrolyte polymer. In a first thermocompression bonding section, the belt-shaped electrolyte polymer and the first reinforcement membrane are thermally compressed. At this time, a molten electrolyte polymer reaches between the first reinforcement membrane and the back sheet thereof, and the first adhesiveness between the first reinforcement membrane and the back sheet thereof becomes higher than the second adhesiveness between the belt-shaped electrolyte polymer and the back sheet thereof. A first peel section peels, in this state, the back sheet from the belt-shaped electrolyte polymer.

A resin composition is provided. The resin composition comprises the following constituents:

(A) an epoxy resin, which has at least two epoxy functional groups per molecule;

(B) a reactive flame retardant with

##STR00001##

(a DOPO functional group) in structure; and

(C) a non-reactive phosphorus-containing flame retardant, which is compatible with the other constituents of the resin composition.

A material sheet is formed of a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. Processes for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet are also provided. A ballistic resistant article which includes the material sheet exhibits excellent antiballistic properties.

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.

There is provided an article a binder resin layer comprising an aliphatic polyurethane polymer comprising a plurality of soft segments, and a plurality of hard segments, where the soft segments comprise poly(alkoxy) polyol, and where the poly(alkoxy) polyol is essentially free of crosslinker; and a plurality of microspheres partially embedded and adhered to a first major surface of the binder resin layer, wherein the specific chemical identities and relative amounts of the segments and moieties of the aliphatic polyurethane polymer are sufficient to impart a glass transition temperature of 10 C. or less in the article and a storage modulus in the article that changes less than 15 MPa from 25 C. to 175 C.

A multilayer structure includes an electrolyte layer and electrode layers each of which is placed on a corresponding one of two principal surfaces of the electrolyte layer. The electrolyte layer includes a mixed ionic liquid containing a plurality of ionic liquids and a base polymer for electrolytes. The electrode layers both include a base polymer, a carbon material, and the mixed ionic liquid. The melting point Tmm of the mixed ionic liquid is lower than the melting point Tm1 of a first ionic liquid which has the lowest melting point among a plurality of the ionic liquids.

The invention relates to a process for the production of fiber composite materials via specific application of monomer mixtures to a surface of a fiber material and subsequently polymerization.
