The invention relates to a process for the production of a high strength transparent high density polyethylene article comprising the steps of (i) heating a high density polyethylene (HDPE) to a temperature above the melting temperature (T.sub.m) of the HDPE; (ii) molding the heated HDPE obtained in step (i) to form a hot molded HDPE article; (iii) cooling the hot molded HDPE article to a temperature below T.sub.m to form a melt-crystallized HDPE article; (iv) stretching the melt-crystallized HDPE article to a total draw ratio of at least 5 comprising at least one stretching step of the article at a temperature T.sub.1 below the melting temperature T.sub.m to a draw ratio (DR.sub.1) of at least 2 to form an oriented HDPE article, wherein the HDPE has a melt flow index (MFI) measured at 21.6 kg and 190 C. according to ASTM D1238 of at most 1.5 g/I Omin, an isotropic density measured according to ISO 1 183-1 A of at most 0.955 g/cm3 and a T.sub.m measured according to ISO 1 1357-3 of greater than 130 C. The invention also relates to high strength transparent HDPE articles and products comprising the high strength transparent HDPE article such as ballistic resistant articles, visors, car parts, train parts, plane parts, windshields, windows and radomes.

Unidirectional transparent projectile penetration resistant panels and bidirectional opaque projectile penetration resistant assemblies and systems and methods of forming and mounting the same relative to underlying support structures.

A method of manufacturing an equine protective covering by applying a stamp comprises a profiled shape with a predetermined temperature and pressure to the interior side of the cushion assembly. The first synthetic fabric layer and the second neoprene layer are permanently bonded. The second neoprene layer is plastically deformed such that the profiled shape of the stamp is permanently transferred to the second neoprene layer. The plastic deformation of the second neoprene layer is such that the perforations remain open.

Resin compositions, layers, and interlayers comprising a poly(vinyl acetal) resin that includes residues of an aldehyde other than n-butyraldehyde are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties as compared to those formulated with comparable poly(vinyl n-butyral) resins.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A mold for use in the production of a ballistic article from a composite laminate stacked material wherein the mold has a sliding sealing section that nests with a outer permitter section and base portion so as to shield the sides of the composite laminate stacked material from applied isostatic pressure applied when in an autoclave. By shielding the sides of the composite laminate stacked material excess resin matrix material can be forced from the composite laminate stacked material to provide a uniform composite article with reduced weight and reduced thickness.

The present disclosure relates to printing apparatus and manufacturing techniques for the manufacture and fabrication of pressure suits and space suits. The disclosure also relates to space suit components formed from additive polymer, and components including one or more layers of a mesh fabric with an applied layer of an additive polymer. One method includes providing an apparatus comprised of a six-degree of freedom motion manipulator with the motion manipulator attached to one or more printing extruder heads. Additive polymers may be extruded via the one or more printing extruder heads to form 3D printed space suit components.

Disclosed herein are methods, apparatus and computer program products for use in manufacturing an anatomical protective item for one or more users. Embodiments of anatomical protective items may comprise a single layer of energy controlling cells. Input data associated with one or more users is obtained. The obtained input data is processed to identify one or more energy controlling criteria for the anatomical protective item. A packing process is employed to generate each energy controlling cell in the single layer. Each energy controlling cell comprises one or more walls which extend from an upper surface of the single layer to a lower surface of the single layer. The packing process is performed at least on the basis of the identified one or more energy controlling criteria. The anatomical protective item comprising the single layer of energy controlling cells is manufactured.

A method of fabricating a polymer composite material by mixing a polymer material with a planar material, depositing the mixture on a substrate, and stretching the resulting thin film, is described. Polymer composite materials produced using said method and ballistic resistant materials comprising said polymer composite materials are also described.

A protector protects a high-pressure fuel pump of an internal combustion engine. The protector and the high-pressure fuel pump are fastened to an engine body by a bolt inserted through a metal collar. The protector further includes an elastic insulating layer located between the collar and a carbon fiber reinforced plastic portion. The collar is embedded in the carbon fiber reinforced plastic portion with the insulating layer compressed.
