More particularly, raw materials included in the composite resin composition for automobile interior products are optimized so that heat resistance and hydrolysis resistance stability are improved. Accordingly, the balance between physical properties such as mechanical properties and fluidity is satisfied and excellent product reliability and appearance can be provided.

The present invention provides a method for manufacturing an air bearing with discreet orifices designed to facilitate a non-contact interface between surfaces. The process involves using a mold wherein wires or filaments are placed to form air channels within a cast. Various materials, such as silicone, steel, and composites, can be used for the mold. After casting and curing the material, the wires are removed, leaving precisely defined channels that allow air to flow through, creating a cushion of air that maintains a gap between the bearing and the surface it operates on. This gap can be adjusted by changing the air pressure or the number of channels. The bearing components may be further machined or secured in a housing connected to an air source, enabling the bearing to hover and operate efficiently in various applications. The invention allows for multiple configurations of the air channels to optimize airflow distribution as required.

The present invention relates to a thermosetting material for use in additive manufacturing, the material comprising at least one thermosetting resin and at least two curing compounds different from said thermosetting resin that are able to cure this/these thermosetting resin(s), wherein at least one curing compound is provided for curing during the additive manufacturing process and at least one curing compound is provided for curing during a post-curing step. The invention furthermore relates to a method of producing a cured 3D thermoset object comprising at least the steps of subjecting the material according to the present invention to an additive manufacturing process, obtaining a partially cured 3D thermoset object and subsequently subjecting the partially cured 3D thermoset object to a post-curing process to further cure the 3D thermoset object Additionally, the invention relates to the use of the material in an SLS, FFF, CBAM, FGF or powder bed additive manufacturing process.

Bonded untreated plastic substrates and process for manufacturing same, including a variable frequency microwave and variable frequency microwave active welding paste. Use of 1-component variable frequency microwave cured paste adapted to wet and bond untreated plastic substrates that is operable to reduce production cycle time, reduce production costs, reduce operating costs, and reduce production line space. Hardening of the welding paste allows joining of thermoplastic panels quickly without the need for panel surface treatment. Polypropylene substrate bonding with 1-component epoxy adhesive that is variable frequency microwave reactive, wherein the substrates are untreated.

A method for recycling prepreg materials including the steps of: a) providing at least one prepreg material including a first thermosetting polymer resin, partially crosslinked, and a weave including fibers, b) applying a vitrimerization reaction mixture to the at least one prepreg material, c) placing the at least one prepreg material coated with the vitrimerization reaction mixture on a mold of a predefined shape, d) applying a thermocompression to the at least one prepreg material at a temperature (T1) greater than or equal to the glass transition temperature (Tg) of the first resin, so as to activate the reaction between the vitrimerization reaction mixture and the thermosetting polymer leading to the formation of a vitrimer polymer and the transformation of the at least one prepreg material into a vitrimer composite material of the predefined shape.
