In this article, the mechanical properties of commercial bulk molding compounds (BMC) based on the unsaturated polyester resin were maximized by optimizing glass fiber weight (FW) and fiber length (FL). An empirical design was utilized to study the influence of each parameter and its interaction on responses. Accordingly, three levels of FW (10, 15, and 20 wt.%) and FL (3, 6, and 12 mm) were used. A full factorial design was utilized to investigate the effect of each variable and their interaction on all responses. The addition of FW improved all the results except flexibility. In addition, all responses increased except the modulus of composites by increasing FL. The compound with 15 wt.% FW and 12 mm FL was chosen as the best toughness-stiffnessstrength equilibrium among the specimens based on optimization outcomes.In addition, the R 2 obtained from the analysis of variance (ANOVA) and normal probability plots showed good compliance between the empirical results and those anticipated using a full factorial model.

“…The properties of SNs/polyester nanocomposites mainly depend on the composition of the inorganic phase, particle size and degree of dispersion [167,168]. The introduction of SNs into polyester can largely improve crystallization properties, mechanical properties and other properties of the nanocomposites [69]. Moreover, the good optical transparency of SNs can be used to obtain fluorescent PETs, further extending application potential of SNs/polyester composites [169].…”

“…The presence of functional groups on the particle surface influences the filler-filler and filler-polyester interactions, and consequently modifies the reinforcement level of the composites [68]. Therefore, the existence of fillers' perfect polyester crystallinity and mechanical strength and other properties [69,70]. In general, clay [71][72][73], carbon nanotubes [74][75][76], graphene [77], zinc powder [78], and silica [79][80][81] were widely used as nano-fillers to improve the crystallization and mechanical properties of polymer substrates.…”

Nano-modification of polyester has become a research hotspot due to the growing demand for high-performance polyester. As a functional carrier, silica nanoparticles show large potential in improving crystalline properties, enhancing strength of polyester, and fabricating fluorescent polyester. Herein, we briefly traced the latest literature on synthesis of silica modifiers and the resultant polyester nanocomposites and presented a review. Firstly, we investigated synthesis approaches of silica nanoparticles for modifying polyester including sol-gel and reverse microemulsion technology, and their surface modification methods such as grafting silane coupling agent or polymer. Then, we summarized processing technics of silica-polyester nanocomposites, like physical blending, sol-gel processes, and in situ polymerization. Finally, we explored the application of silica nanoparticles in improving crystalline, mechanical, and fluorescent properties of composite materials. We hope the work provides a guideline for the readers working in the fields of silica nanoparticles as well as modifying polyester.

“…It indicated that more external impact energy absorbed by chopped E-glass fibers and those composite materials presented better mechanical properties. It was reported that E-glass fiber was modified by styrene-butadiene rubber (SBR) and fumed silica, and it was utilized in unsaturated polyester resin to prepare fiber reinforced composites [ 12 ]. Below ambient temperature, E-glass fiber reinforced unsaturated polyester resin performed a uniform brittle property, but it exhibited reasonable ductility at and above ambient temperature [ 13 ].…”

Long chopped glass fiber reinforced low-density unsaturated polyester resin (LCGFR-LDUPR) composite materials with light weight and excellent mechanical properties were prepared. It was proved that long chopped glass fiber, which was in length of 15.0 mm and chopped from ER4800-T718 plied yarn, was suitable for the preparation of LCGFR-LDUPR composite samples. With the coexistence of 1.50 parts per hundred of resin (phr) of methyl ethyl ketone peroxide (MEKP-II) and 0.05 phr of cobalt naphthenate, optimal preparation parameters were obtained, which were 20.00 phr of long chopped glass fiber, 2.50 phr of NH4HCO3, at a curing temperature of 58.0 °C. The lowest dosage of activated radicals produced by MEKP-II and cobalt naphthenate enabled the lower curing exothermic enthalpy and the slowest crosslinking for unsaturated polyester resin to carry out, resulting in a higher curing degree of resin. It was conducive to the formation, diffusion, and distribution of bubbles in uniform size, and also for the constitution of ideal three-dimensional framework of long glass fibers in the cured sample, which resulted in the LCGFR-LDUPR composite sample presenting the apparent density (ρ) of 0.68 ± 0.02 g/cm3, the compression strength (P) of 35.36 ± 0.38 MPa, and the highest specific compressive strength (Ps) of 52.00 ± 0.74 MPa/g·cm3. The work carried out an ideal three-dimensional framework of long chopped glass fiber in the reinforcement to low-density unsaturated polyester resin composite samples. It also presented the proper initiator/accelerator system of the lower curing exothermic enthalpy and the slowest crosslinking for unsaturated polyester resin.
