A method for manufacturing a blade shell part of a wind turbine blade includes providing a mould for manufacturing a blade shell part of the wind turbine blade. The mould has a first moulding side with a first moulding surface that defines an outer shape of the blade shell part. The method comprises providing a blade shell part on the first moulding surface and providing a support element and attaching the support element to a fastening section of the blade shell part. Attaching the support element includes applying adhesive between the support element and the fastening part. The method also includes providing an air heating assembly having a cover extending in a longitudinal direction between a first cover end and a second cover end and extending in a transverse direction between a primary cover end and a secondary cover end, the cover defining a cavity.

“IMPROVEMENT INTRODUCED IN THE PROCESS OF OBTAINING THERMO-STRUCTURAL COMPOSITES”, resulting from the union of various synthetic materials (F), which go through a phase of couplings (union of materials), to be subsequently heated and pressed into molds (M) of specific size for each part to be molded, at temperatures and pressure suitable for the fusion of these elements, featured by the fact that the thereto-structural composite (1) is obtained from the formation of the substrate (S), with the synthetic fiber molding (F), foams, etc., preferably Non-Woven (NW-TNT)+PE Film+Fiberglass+Semi-Rigid PU Foam embedded in a chemical formulation (FO) of Diphenylmethane Diisocyanate (MDI) in a ratio of 30% to 80% and Methylene Chloride (CM) in the ratio of 20% to 70%; and for processing the product, a catalyst prepared from Dabco Cristal in the ratio of 1% to 30% is used; by adding 70% to 99% water, said substrate (S) may, during the hot-molding phase, receive the addition of finishes (5) and, after the molding phase, receive the addition of minor and complementary structural elements (6).

Disclosed are a composite resin composition containing a thermosetting resin including an unsaturated polyester resin and a saturated polyester resin, a filler, and a processability-improving agent. More particularly, disclosed are a composite resin composition that is capable of providing a molded article having a lower specific gravity and improved surface quality compared to a conventional molded article by improving the compatibility and impregnability of a thermosetting resin and a filler using a processability-improving agent, and a molded article manufactured using the same.

A joint member is formed of a composite including reinforcement fibers and resin. The joint member is configured to be joined with another joint member to form a joint structure capable of enduring a tensile load in a load direction in which the joint member and the other joint member are separated from each other at a joined portion of the joint structure in a longitudinal direction of the joint member. The joint member includes a main body part and a joint part connected with the main body part at an end part of the main body part in the longitudinal direction of the joint member. The joint part has an orientation pattern having anisotropy such that fiber directions of the reinforcement fibers included in the joint part include a fiber direction different from the longitudinal direction of the joint member.
