The composite plates include a spheres or microspheres dispersed/embedded in a carrier polymer. The spheres or microspheres provide one or more of thermal protection, sonic/blast resistance, and ballistic protection.

A film includes a polymeric material and a plurality of particles dispersed therein. The polymeric material includes a plurality of elongate polymeric elements oriented along substantially a same first direction and interconnecting the particles. A ratio of a volume of the plurality of particles to a volume of the polymeric material is at least 5. An elongate portion of at least a first elongate polymeric element in the plurality of elongate polymeric elements may conform to and be bonded to a first particle in the plurality of particles along an entire length of the elongate portion. The first elongate polymeric element may extend from the elongate portion at least to a second particle in the plurality of particles.

A method to manufacture a bevel at least partly along at least one edge of a building panel, such as a floor panel or wall panel, where the building panel comprises a substrate having an inorganic filler of an amount of 50-85 wt % and a polymer-based material. The method comprising heating at least an edge portion of an edge of the building panel, along which edge the bevel is to be formed, and forming the bevel in said edge portion by applying pressure to said portion, where the bevel is at least partly formed in the substrate.

An article comprises a substrate having a first portion comprising at least one of a metal or a ceramic metal oxide. A composite foam is bonded to the metal or ceramic metal oxide. The composite foam comprises: at least one polymer preparable by ring-opening metathesis polymerization; at least one catalyst for the ring-opening metathesis polymerization; at least one difunctional coupling agent represented by ZXZ. Each Z independently represents a group that is chemically reactive with at least one of the chemically bound surface hydroxyl groups thereby forming at least one covalent bond. Each X independently represents a divalent organic linking group having a number average molecular weight of 500 to 10000 grams per mole; and at least one of hollow glass microspheres or expanded polymeric microspheres. A method of making the article is also disclosed.

A Hybrid Vessel Propulsion and Generation System diesel jet drive outboard and inboard motors, with an electrical generator attached to a prop shaft of the motors to generate electricity to power batteries. On large boats or ships with a gear change, the generator is mounted on the back of the gearbox and is attached to the prop shaft, with the generator being driven by rotation of the prop shaft and the drive off the gearbox. The system also incorporates electrically powered water thrusters and mechanical pressurized water turbines used for charging the batteries. The system also incorporates electric motors attached to propellers powered by electric batteries. Solar Panels may be arranged in the port hole windows incorporating a housing, latch and lever arms to position them towards the sun.

A layered composite includes: a foam core made of a plastic foam; and a first cover layer and a second cover layer, between which the foam core is arranged, wherein at least one of the cover layers is a fiber material layer containing reinforcement fibers embedded in plastic. A plastic resin fills intermediate spaces between the cover layers in and around the foam core and holds the cover layers and the foam core together. The layered composite includes a fire protection layer made of a composite material on a side of the fiber material layer facing away from the foam core. The composite material contains hollow micro-bodies made of ceramics or glass in a plastic material.

An enhanced performance roofing membrane, having: (a) a bottom membrane layer; (b) a top membrane layer; (c) a scrim layer between the top and bottom membrane layers; and (d) a reduced density membrane layer between the top and bottom membrane layers. The reduced density membrane layer may be a foamed layer, or a layer of polymer with gas pockets or beads therein. The reduced density layer may be made of the same materials as the top and bottom layers.

A plurality of glass bubbles having, in combination, a D50 size of no greater than 13 micrometers, an average true density of no greater than 0.42 grams per cubic centimeter, and a 90% crush strength of at least 55 megapascals are described.
