FDM-printing technology is widely used in many fields including highly responsible industries such as aerospace, oil and gas and automotive manufacturing. Polyphenylene sulfone and its composites are one of the most common used high-performance polymers in those fields but polyphenylene sulfone is expensive and the lower material would be used for production the more applications could be able to enroot polyphenylene sulfone to their industries. Additive manufacturing opens new boundaries comparing to traditional technologies allowing to use the grid filling of parts which can help to reduce the material expenditure. In this research the influence of grid filling to mechanical properties of polyphenylene sulfone and its carbon-filled composite samples obtained using FDM-printing technology was studied. The article includes results about the effect of various grid sizes and its type on the mechanical properties of polyphenylene sulfone and its carbon-filled composite samples, and It shows the possibility of significant material savings while maintaining the required product properties.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.

Diphenyl Sulfone

A series of random polysulfone/polyethersulfone (PSF/PES) copolymers were synthesized by the polycondensation of 4, 4'-isopropylidendiphenol, 4, 4΄-dihyolroxy diphenyl sulfone and 4, 4'-dichlorodiphenyl sulfone in the presence of K2CO3. We obtained a series of copolymers by changing the molar ratio of 4, 4΄-dihyolroxy diphenyl sulfone and 4, 4'-isopropylidendiphenol (it was marked as the ratio of S:A). The copolymers have the similar solubility with polyethersulfone. They also have high glass transition temperatures (Tg: 199°C~229°C) and 5% weight loss temperatures (4, 4'-isopropylidendiphenol: 4, 4΄-dihyolroxy diphenyl sulfone=1:1, Td5=497°C). At the same time the elongation at break is much higher than that of PES, while the tensile strength is a little lower than that of PES.
