Disclosed is an apparatus and methods for sintering particulate to make a workpiece.

Apparatus and methods for sintering

A robust sintered retroreflective composite comprising, a core bead, a peripheral bead, and an interphase coating. The bead can be used in typical retroreflective indicia and uses.

Retroreflective composite reflective microspheres and reflective inorganic material

Embodiments herein relate to a composite material including about 10 to 80 wt. % of a polymer phase, the polymer phase comprising a thermoplastic polymer with a density of less than about 1.9 g-m-2; and about 20 to 90 wt. % of a dispersed mixed particulate phase, the dispersed mixed particulate phase comprising a mixed particulate and about 0.005 to 8 wt. % of a coating of at least one interfacial modifier. The mixed particulate including a portion of a reinforcing fiber and a portion of a particle. The composite material having a Young's modulus of greater than 700 MPa. In various embodiments, structural building components made from the composite are included as well as additive manufacturing components made from the composite. Other embodiments are also included herein.

Polymer composite comprising an interfacially modified fiber and particle

A retroreflective composite bead for highway marking having high retroreflectivity both when initially installed and over the bead lifetime, allowing vehicle drivers to see highway marking lines at night and in adverse conditions during nighttime. When installed the retroreflective beads essentially retroreflect the base color of the highway marking material in which the retroreflective beads are embedded. The beads comprise a larger bead with a coating of smaller particles heat bonded to its surface.

Complex retroreflective bead

A polymer compatible retroreflective bead. The bead can be used in typical retroreflective uses such as paints tapes and films in highway marking and signs having high retroreflectivity both when initially installed and over the bead lifetime, allowing vehicle drivers to see highway marking lines at night and in adverse conditions during nighttime. When installed the retroreflective beads essentially retroreflect the base color of the highway marking material in which the retroreflective beads are embedded.

Polymer compatible heat fused retroreflective bead

Sliding joinery

Disclosed is a composite of a particulate and polymer, the composite characterized by less than enough polymer to fully occupy the available excluded volume of the particulate of the composite. The resulting composite is characterized by the particulate partially covered by the polymer leaving a substantial surface area uncovered.

Reduced polymer content and bonding in polymer particulate composite

The invention relates to a hollow glass microsphere and polymer composite having enhanced viscoelastic and rheological properties.

Reduced density hollow glass microsphere polymer composite

An advanced siding panel that combines a traditional siding appearance with improved insulation, structural integrity, and improved thermal characteristics.

Structural siding panel with improved thermal and mechanical properties

The claimed material relates to a mixed silica and silicate fiber and polymer composite having enhanced modulus, viscoelastic and rheological properties.

Silica and silicate blended fiber polymer composite

The claimed material relates to a fiber and polymer composite having enhanced modulus, viscoelastic and rheological properties.

Fiber polymer composite

Reinforced structural siding panel with improved thermal and mechanical properties
