Carbon fiber reinforced plastic is a kind of reinforced carbon fiber and fiber reinforced plastic is. Epoxy resins are mainly used as substrates. It is simply called carbon resin or carbon.Carbon fiber reinforced plastic has high strength and lightness. The field of construction includes seismic strengthening of buildings and bridges since the 1990s, has begun practical use in sports applications such as golf shafts and fishing rods, and has expanded to the aircraft and automotive industries. But it is widely used.The properties of carbon composites are mainly manifested in three aspects: mechanical properties, thermophysical properties and thermal ablation properties.(1) Low density (about 1.7g/cm3) It is the lightest material in the structure that withstands high temperature; the strength at high temperature is good, and the room temperature strength can be retained at 2200 °C; it has high fracture toughness and fatigue resistance. and creep resistance; and the tensile strength and ...

Fiber-reinforced composite materials are composite materials formed by reinforced fiber materials, such as glass fibers, carbon fibers, aramid fibers, etc., and matrix materials through lamination, molding or pultrusion.This series of materials has the characteristics of light weight, high strength, good chemical resistance, diversified structural design, adjustability of dielectric constant and dielectric loss (wave permeability + shielding + antenna design), etc., and is widely used in the field of consumer electronics. There are broad application prospects.The core technology of fiber reinforced composite materials is mainly reflected in the following three aspects:Resin synthesis technology: This is a very important part. Enterprises need to have original resin formulations and synthesis technology, so that they can reach the industry leading position and have their own intellectual property rights, and the competitive advantage will be very large;Composite technology: own patent c...

Introduction ofRTMmolding process and classification1. RTM molding process and classificationRTM refers to a process technology in which a low-viscosity resin flows in a closed mold, infiltrates the reinforcing material, and solidifies and forms. It belongs to the liquid forming or structural liquid forming technology category of composite materials. The specific method is to put reasonably designed, cut or mechanized pre-formed reinforcing materials in the designed mold in advance. The mold needs to be sealed and tightened around the periphery to ensure smooth flow of the resin; after the mold is closed, a certain amount of resin is injected. After the resin is cured, the mold can be demolded to obtain the desired product.SMC, BMC molding, injection molding, RTM, and VEC technologies are all closed-mold molding processes. Due to the formulation of environmental laws and the improvement of product requirements, open-mold composite materials are increasingly restricted, which has prompt...

Fiber-reinforced composite materials are the use of characteristic continuous fibers or continuous fiber products as reinforcing materials. The composite materials formed by bonding these reinforcing materials with adhesives are called fiber-reinforced composite materials. Formerly called fiber-reinforced plastic. This composite material is divided into aramid fiber composite material, glass fiber composite material and carbon fiber composite material.Carbon fiber is made of polyacrylonitrile fiber, viscose or pitch filament by carbonization. Due to different raw materials and different manufacturing methods, the strength and modulus of carbon fibers are also different. The relative density of carbon fiber is 1.3-1.8, while the relative density of glass fiber is about 2.5; the tensile strength, bending strength and modulus of carbon fiber reinforced composite materials are significantly higher than those of glass fiber reinforced composite materials.The thermal expansion coefficient of...
