WELDABLE THERMOPLASTIC COMPOSITE COMPOSITES
20220379568 · 2022-12-01 · ·

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

AUTOMOBILE LAMINATED GLASS

A automobile laminated glass according to the present invention includes: a curved outer glass plate; a curved inner panel that is smaller than the outer glass plate and is disposed opposing the outer glass plate; and an intermediate film that includes a functional layer and is disposed between the outer glass plate and the inner panel, wherein at least a portion of the inner panel is located inward of a peripheral edge of the outer glass plate.

Polyurethane film comprising graphene and preparation process thereof

A polyurethane film comprising a polyurethane resin and graphene, wherein the graphene is present in an amount of 1 to 30% by weight on the total weight of the film and consists of graphene nano-platelets, wherein at least 90% has a lateral dimension (x, y) of 50 to 50000 nm and a thickness (z) of 0.34 to 50 nm, wherein the lateral dimension is always greater than the thickness (x, y>z), wherein the C/O ratio is ≥100:1, and a preparation process thereof.

Ethylene-vinyl alcohol copolymer composition, pellets, and multilayer structure

An ethylene-vinyl alcohol copolymer composition is substantially free from coloration, and contains: (A) an ethylene-vinyl alcohol copolymer; (B) a polyamide resin; and (C) an iron compound; wherein the iron compound (C) is present in an amount of 0.01 to 20 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition.

A thermoplastic elastomer compound includes a polyolefin elastomer blend of at least two different polyolefin elastomers, styrene-ethylene/butylene-styrene block copolymer, and plasticizer. The compound has a Melt Flow Rate (230° C., 2.16 kg) of no less than about 5 g/10 min and a Melt Flow Rate (190° C., 2.16 kg) of no less than about 1 g/10 min. Elastomeric films formed from the compound can be used in place of elastomeric films based on styrene-isoprene-styrene (SIS) block copolymers to make components of disposable hygiene articles.

WEDGE-SHAPED MULTI-LAYER INTERLAYER WITH OUTER SKIN LAYERS OF VARYING THICKNESS

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.
