The invention relates to a waterproof foam concrete formula and a preparation method thereof. The formula is prepared from 60 to 70 parts of cement, 0 to 18 parts of coal ash, 1 to 2 parts of a fiber,5 to 10 parts of a foaming agent, 0.5 to 2 parts of a waterproofing agent, 0.5 to 2 parts of an additive and 15 to 25 parts of water. The preparation method comprises three steps of pulping, foamingand mixing. By the adding of the waterproofing agent, the waterproof foam concrete formula is waterproof and is difficultly affected by moisture so as to ensure that the heat preservation and heat isolation performance is exerted fully; the waterproof foam concrete can meet the requirements for strength and heat preservation by reasonably regulating the proportions of the cement and the foaming agent and controlling the foaming time; and furthermore, the mass can be reduced, and the convenience in construction is improved.

The thickness of the aluminum layer or the aluminum alloy layer is in a range from 0.3 to 1.0mm, and the thickness of the stainless steel layer is in a range from 0.05 to 0.3mm. The terminal housing has a metal appearance, which is a unique characteristic of the stainless steel, and the appearance surface has high glossiness and low production costs. The invention also provides a terminal comprising the terminal housing.

The invention discloses a novel automotive front and rear wall, and relates to the technical field of automobiles. The novel automotive front and rear wall comprises reinforcement layers (1) and resin layers (2). The five layers including the reinforcement layer (1), the resin layer (2), the reinforcement layer (1), the resin layer (2) and the reinforcement layer (1) are sequentially arranged from the outermost layer to the innermost layer of the novel automotive front and rear wall. The novel automotive front and rear wall has the advantages that the novel automotive front and rear wall is high in strength as compared with an automotive front and rear wall which is made of common glass fiber reinforced plastic materials, is light, non-conducting and corrosion-resistant, and is difficult to deform and break under the condition of low impact, and the like.

The invention provides an optimization method for replacing plastic with metal for an automobile rear anti-collision beam for a CAE (Computer Aided Engineering) crash simulation technology. On the basis of the CAE crash simulation technology and the rear anti-collision beam of traditional metal, the rear anti-collision beam of the traditional metal is changed into the rear anti-collision beam of plastic, a verification result shows that a rear collision working condition and a rear low-speed collusion working condition CAE analysis result meet a target value requirement, and a rear automobileexperiment verifies that the rear collision of the rear anti-collision beam of plastic and rear low-speed collision meet requirements. The rear anti-collision beam of plastic has the advantages of light quality, corrosion resistance, fatigue resistance, good toughness and low cost.
