This compilation serves as a valuable resource, providing insights into the latest trends and breakthrough solutions that have garnered attention and acclaim in the field of composite materials. Based on Google Analytics data, CW has compiled the top ten products with the highest page views.
Global resin market faced a 2.5% decline in 2023 due to economic slowdown, rising material costs, and COVID-19. Renewable energy and electric vehicles propel resin demand, while bio-based resins gain attention. Mergers and acquisitions aim to strengthen industry positions. Despite challenges, opportunities emerge in sustainable applications.
Electronics, Saudi Petrochemical, Hong Kong Water Group, BMW, etc. Mr. Yan Zhenghua, the Director of AOC, has affirmed Wan Qing's work in AOC brand building over the years and has high expectations for the new fiscal year. At the same time, AOC has set sales targets for the new year and will increase its support for Evergreen, from professional knowledge training to expanding key customers and developing new applications. Injecting new impetus into continuous innovation in the resin field is an unchanging pursuit for both parties.
Today we will talk about gel coat and its application, and why boats must use m-phenylene neopentyl glycol gel coat.Although FRP does not rust or rot, like steel and wood products, its surface is often coated with a layer of substances that can meet its weather resistance, water resistance, corrosion resistance and other special performance requirements. Gel coat resin is the most commonly used One, the gel coat resin is sprayed on the surface of the mold before the fiberglass product is molded, and then after the molded product is demoulded, there is a layer of gel coat resin on the surface.
As widely acknowledged, Fiberglass Reinforced Plastic (FRP) is an amalgamation of materials, primarily glass fibers and resin. While the curing agent constitutes a small fraction, Methyl Ethyl Ketone Peroxide (MEKPO) emerges as the most commonly used curing agent in ambient-temperature curing processes for FRP. Despite its minimal usage (typically 1%-2% of resin volume), MEKPO plays a pivotal role in adding the finishing touch to the quality of FRP products. Unfortunately, the extensive applications of MEKPO have given rise to unscrupulous practices, with dishonest businesses manufacturing imitation and substandard curing agents to cut costs, leading to a disturbing trend where over half of the current curing agent issues stem from quality non-compliance. Consequently, substandard curing agents have become a significant threat in the present FRP industry.
Organic peroxides are prone to exothermic decomposition at room or high temperatures. Heating, contact with impurities (such as acids, heavy metal compounds, amines), friction or collision can cause decomposition.Organic peroxides are classified into 7 types based on their level of danger.
Sandwich composite structure and vacuum infusion process：The vacuum injection molding process is rapidly being adopted by large and small composite material manufacturers throughout the industry。
Evergreen Chemicals offers peroxides for rubber, Nouryon organic peroxides like PERKADOX® BC-FF, 14S-FL, PD-50S-PS, 14-40B-PD, TRIGONOX® 145-E85, 101-45B-PD, 101-45D-PD, 101-45S-PS that are formulated to crosslink a variety of low and high durometer silicones in food grade or industrial applications. Each grade has a very fine particle size to mix easily.
The most distinctive feature of the Boeing 787 is its extensive use of advanced composite materials, even the fuselage is made of composite materials, which account for approximately half of its structural weight. By comparison, the proportion of 757 aircraft is approximately 7%, while that of 777 aircraft is approximately 11%.
In November, the trend of epoxy resin market was weak, with weak downstream demand for resin. Manufacturers faced greater pressure to ship and fierce competition at low prices.
Pultrusion composite material is a high-performance fiber reinforced polymer (FRP) composite material manufactured using a continuous process called pultrusion. Here, continuous fibers (such as glass or carbon) are pulled through a thermosetting resin bath (such as epoxy resin, polyester, or vinyl ester) and then molded to form the desired shape. Then the resin solidifies to form a sturdy, lightweight, and durable composite product.
Pultrusion process is a method of continuous production of composite profiles. It involves impregnating the untwisted glass fiber coarse yarn and other continuous reinforcement materials, polyester surface felt, etc. on the yarn frame with resin, and then using a molding mold that maintains a certain cross-sectional shape, and curing it in the mold to form a continuous mold, thereby forming an automated production process for pultrusion products.
The epoxy resin market experienced weak fluctuations after a broad decline in October. In the first half of the month, dual raw materials, especially bisphenol A, saw a broad decline, and the cost support of epoxy resin collapsed significantly. After the National Day holiday, downstream markets were mainly wait-and-see, and the market buying atmosphere was poor. Affected by negative costs and demand, resin prices continued to decline.
Resin Transfer Molding (RTM) is a new composite material molding process that has evolved from wet layup and injection molding processes.
Recently, Hou Xianglin and Deng Tiansheng, researchers of Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences, have spent years of painstaking research and mastered the technology of "disassembling" the main material of fan blades - carbon fiber reinforced thermosetting resin composites (thermosetting resin directional degradation and resource utilization technology), turning the "ultimate material" into a treasure and realizing the recycling of solid waste of fan blades, Completed the last link of green and low-carbon circular development in the wind power industry chain.
From September 12th to 14th, the 2023 China International Composite Materials Industry Technology Exhibition concluded at the National Convention and Exhibition Center (Shanghai).At the exhibition, Mr. Yan Zhenghua, Marketing and Sales Director of AOC China/AOC, accepted an interview with the China Composite Materials Industry Association, introducing the performance advantages of the exhibits and expressing his views on the market and development of the composite industry.
Global leader in specialty chemicals, Nouryon, has announced that it will invest in its production base in Ningbo, China to significantly increase the production capacity of organic peroxide products.
