Polyester resin composition, molded article, and composite molded article
A composite molded article obtained by laser welding molded article composed of a polyester resin composition having a crystallinity of 15% or more as calculated with fast scanning calorimetry by a calculation method, wherein the calculation method includes using fast scanning calorimetry, the polyester resin composition is heated from 30° C. to 260° C. at 10000° C./second, then maintained at 260° C. for 0.1 second, then cooled to 80° C. at 5000° C./second, maintained at 80° C. for 0.1 second, then cooled to −70° C. at 5000° C./second, and then heated to 260° C. at 1000° C./second, after which the curve obtained is used to calculate the crystallinity.
ECO-FRIENDLY WEARABLE DIPPED ARTICLE AND METHOD OF MANUFACTURING
The present invention generally relates to an eco-friendly wearable article comprising a nutrient complex capable of efficiently able to reduce or eliminate methane gas emission during biodegradation of the article, and a method of making the eco-friendly wearable article containing the nutrient complex. Preferably, the nutrient complex typically comprises anionic sulphate ions and cationic salts of iron(II) and copper(II), thereby facilitating methane oxidation in an anaerobic environment such as a landfill.
Method for manufacturing a turbomachine composite part
Methods for manufacturing a turbomachine composite part, such as a fan blade, are provided. The composite part has a fibrous structure with a three-dimensional fibrous preform coated with a surface fibrous web, and which is embedded in a polymer matrix The methods include: forming the surface web in a cavity of a mold in order to shape it, wetting and forming the preform on the surface web in order to shape it, and closing the mold, drying the fibrous structure, and injecting thermosetting resin into the mold in order to form said polymer matrix. The surface web is wetted before and/or during the forming thereof.
