Nanofibrillar polymer–polymer composites (NFCs) and single polymer composites (SPCs) were produced using linear low density polyethylene (LLDPE) and poly(vinylidene fluoride) (PVDF). The NFCs were fabricated by means of a microfibrillar composite concept comprising melt blending, cold drawing, and compression molding retaining the highly oriented PVDF ...

Multilayer polymer GRIN singlets: manufacturing and performance
International Optical Design Conference 2021, 2021The design and performance of two multilayer polymer gradient index (GRIN) singlets are discussed. One singlet is an f/4 monochromat based on an axial GRIN geometry. The other is an f/6 achromat based on a spherical GRIN geometry. The design for each lens was modified to account for as-manufactured GRIN contours and final layer thicknesses ...

Manufacturing and Testing of Shape Memory Polymer Composite Actuators
2023Shape memory (SM) polymer composite (PC) actuators have been manufactured by using carbon fibre reinforced (CFR) prepregs and by integrating flexible heaters. The smart device has the structure of a composite sandwich with CFR plies as external skins, an embedded heater and SMP layers in between.

Tutorial on Polymers – Manufacture, Properties, and Applications
2022Over half a century, polymers/plastics have penetrated all facets of modern human life by providing convenience and comfort at low cost. But irresponsible disposal has also led to unacceptable littering of the environment. This tutorial chapter will review the status of today's plastics economy, from manufacture, to applications with respective ...

Additive Manufacturing Technologies for Polymers and Composites
2015ABSTRACT In this chapter, we describe additive manufacturing (AM) processes for polymers and for composites where polymers are used. These include cases where polymers are the only material used, where they are added as binders in the case of ceramics, and in polymer composites where they are used either as a thermoplastic resin or as a thermoset ...
