The First plastic sabots were made of glass-fiber filled diallylphthalate sheathed in nylon and they included metal reinforcements whenever it was felt necessary to redistribute the stresses. The nylon sheath was necessitated by the abrasive nature of glass-filled materials. Nylon also is used for rotating bands on projectiles and on metal sabots. Other plastics used for the structural portions of sabots include poly propylenes, polycarbonates, celluloses, epoxies and phenolics. Polyethylene, neoprene, and silicone rubbers are used for seals and obturators... 

In general, rigid plastics are superior to elastomers in radiation resistance but are inferior to metals and ceramics. Examples of materials, which will respond satisfactorily in the range of 10 and 10 erg per gram, are fluoroplastics, glass fiber-filled phenolics, certain epoxies, polyurethane, polystyrene, mineral-filled polyesters, silicone, and fiirane resins. The next group of resins in order of radiation resistance includes polyethylene, melamine, urea formaldehyde resins, unfilled phenolic, and silicone resins. Those materials, which have poor radiation resistance, include methyl methacrylate, imfilled polyesters, cellulosics, polyamides, and fluorocarbons (Tables 9.16 and 9.17).

General discussions of the effect of reinforcing agents on the thermal properties of polymers include glass fiber-reinforced polyethylene terephthalate [28], multiwalled carbon nanotube-reinforced liquid crystalline polymer [29], polysesquioxane [30, 31], polynrethane [31], epoxy resins [32], polyethylene [33], montmorillonite clay-reinforced polypropylene [34], polyethylene [35], polylactic acid [36, 37], calcium carbonate-filled low-density polyethylene [38], and barium sulfate-filled polyethylene [39].

They are fabricated from a variety of inorganic, organic, and naturally occurring materials and generally contain pores that are greater than 50—100 A in diameter. Materials such as nonwoven fibers (e.g. nylon, cotton, polyesters, glass), polymer films (e.g. polyethylene (PE), polypropylene (PP), poly(tetrafluo-roethylene) (PTFE), poly (vinyl chloride) (PVC)), and naturally occurring substances (e.g. rubber, asbestos, wood) have been used for microporous separators in batteries that operate at ambient and low temperatures (<100 °C). The microporous polyolefins (PP, PE, or laminates of PP and PE) are widely used in lithium based nonaqueous batteries (section 6.1), and filled polyethylene separators in lead-acid batteries (section 7.3), respectively.

It should be noted that the formation of the filler structural lattice in thermoplastics can also affect the viscoelastic properties (143). The viscoelastic properties of and PMMA filled with aerosil and glass fiber have been examined in (149) in which the role of the filler and polymer nature was demonstrated as well as their interaction in response to those properties. The dynamic properties of filled polyethylene, poly-propylene, and of a number of other polymers have been investigated in (72) where they are treated from the point of view of changes in the molecular mobility. A nundier of other reports on those problems have been published (145-148). The principal findings of these studies confirm our concepts related to effects of molecular mobility on the viscoelastic properties. However, in contrast to the studies of filled resins, the filled thermoplastics were examined only by the use of common... 

The tubular positive plate uses rigid, porous fiber glass tubes covered with a perforated plastic foil as the active material retainer (Fig. 2). Dry lead oxide, PbO, and red lead, Pb O, are typically shaken into the tubes which are threaded over the grid spines. The open end is then sealed by a polyethylene bar. Patents describe a procedure for making a type of tube for the tubular positive plate (90) and a method for filling tubular plates of lead—acid batteries (91). Tubular positive plates are pickled by soaking in a sulfate solution and are then cured. Some proceed directiy to formation and do not requite the curing procedure. 

Janick and Kroliskowski [40] investigated the effect of Charpy notched impact strength on the flexural modulus of polyethylene and polyethylene terephthalate. Polymers with good flexural modulus include polydiallylisophthalate (11.3 GPa), phenol-formaldehyde (6.5 GPa), alkyd resins (8.6 GPa), and polyphenylene sulfide (13.8 GPa), as well as glass-filled polyester laminate (16 GPa) epoxy resins (3-3.5 GPa), sUica-fiUed epoxies (15 GPa), and acetals containing 30% carbon fiber (17.2 GPa).
