Improving the Thermal Properties of Polycarbonate via the Copolymerization of a Small Amount of Bisphenol Fluorene with Bisphenol A

open access: yesInternational Journal of Polymer Science, 2022
Polycarbonate is an attractive transparent plastic with high mechanical/thermal properties. A family of copolycarbonates of bisphenol-A (BPA), 9, 9-bis (4-hydroxyphenyl) fluorene (BHPF), and diphenyl carbonate (DPC) were prepared by a transesterification

Comparison of several closure approximations for evaluating the thermoelastic properties of an injection molded short-fiber composite [PDF]

open access: yes, 2007
The accurate prediction of both the elastic properties and the thermal expansion coefficients is very important for the precise simulation of such processes as injection molding of short-fiber polymer-matrix composites.

Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]

open access: yes, 2011
Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,

Effect of pretreatment on microstructural stability and mechanical property in a spray formed Al-Zn-Mg-Cu alloy

open access: yesMaterials & Design, 2021
Aluminum alloys fabricated by spray forming (SF) technology are commonly followed by hot-working without heat treatments. A new approach that is a pretreatment before hot-working is proposed in the present work.
