CO2-assisted polymer compression (CAPC) is an environmentally friendly processing method that uses CO2 to plasticize and crimp fibers at room temperature, enabling low-energy within a short time. In this study, CAPC was applied polylactic acid (PLA), carbon-neutral polymer. To evaluate the relationships between plasticization crystallinity degree of PLA, samples with different degrees were laye...

The moisture absorption behavior and the influence of moisture on thermal and mechanical properties of glass–fiber/polyetherimide (PEI) laminates have been investigated. The laminates were exposed to hydrothermal aging at two different temperatures and high moisture rates. The properties of as-received and hydrothermally aged samples were compared. The hydrothermally aged laminates contained a ...

In this research an attempt is made to modify the brittle poly (Lactic acid) (PLA) into flexible PLA by adding Poly (Butylene Succinate) (PBS), Poly (Ethylene Glycol) (PEG) and Ricinoleic acid (R.ACID) as a plasticizer. Various plasticizers with different weight % of plasticizers 10%, 20% and 30% in wt% for PLA/PBS, 5, 10 and 15% for PLA/PEG and PLA/R.ACID are used to make sheets. With the addi...

Atomistic molecular dynamics simulations were performed on a low molecular weight nitroplasticized Estane® mixture representative of the binder used in PBX-9501. Pressurevolume-temperature (PVT) behavior over a wide range of pressure and temperatures above the order-disorder temperature (ODT) of Estane was determined and represented with the empirical Tait and Sun equations-of-state. The effect...
