Embodiment 1

[0026] An engine bottom guard plate and its production process, the engine bottom guard plate is made of continuous fiber reinforced thermoplastic material and lightweight thermoplastic reinforced material (LWRT), comprising the following steps:

[0027] (1) Heating: heat the continuous fiber reinforced thermoplastic material in a heating device, the temperature acting on the surface of the plate is 200°C, and the heating time is 45s; place the lightweight thermoplastic reinforced material (LWRT) in another heating device to heat, The temperature acting on the surface of the plate is 220°C, and the heating time is 60s; further, the heating device uses an infrared heating box, which has obtained a more uniform heating temperature field;

[0028] (2) Transfer: In the first transfer step, the preheated continuous fiber-reinforced thermoplastic material is transferred to the mold through automatic equipment, and the transfer time is 2s; in the second transfer step, the preheated li...

Embodiment 2

[0040] An engine bottom guard plate and its production process, the selected area density is 1200g / m 2 continuous fiber-reinforced thermoplastic material with an area density of 1400g / m 2 The lightweight thermoplastic reinforced material (LWRT), the two kinds of plates are cut to the corresponding size according to the size of the product.

[0041] (1) Heating: Using an infrared heating device, place the continuous fiber reinforced thermoplastic material in the heating device for heating. The temperature acting on the surface of the plate is 210°C, and the heating time is 70s; place the lightweight thermoplastic reinforced material (LWRT) in another Heating in the infrared heating device, the temperature acting on the surface of the plate is 210°C, and the heating time is 60s;

[0042] (2) Transfer: In the first transfer step, the manipulator cooperates with the vacuum suction cup grasping device to transfer the preheated continuous fiber reinforced thermoplastic material to ...

Abstract

The invention belongs to the technical field of automobile part preparation, and discloses an engine bottom protection plate which is composed of a continuous fiber reinforced thermoplastic material and a light thermoplastic reinforced material, which are in fusion connection through resin. The invention further discloses an inspection process of the engine bottom protection plate. The engine bottom protection plate is formed through steps of: baking and heating, rapid transfer, stacking, compression molding, and cutting in later period. According to the production process of the multi-material composite engine bottom protection plate, the problem of connection strength among multiple materials is solved through material preheating temperature control and transfer duration optimization, and the prepared engine bottom protection plate has the advantages of being good in strength region designability, excellent in impact resistance, light in weight and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile parts preparation, and in particular relates to an automobile engine bottom guard plate and a production process. Background technique [0002] The engine bottom guard is a protective device installed under the car engine to protect the bottom of the engine from impact. With the development of automobile technology, the requirements for the engine bottom guard are gradually increasing. On the premise of meeting the basic impact resistance, requirements such as light weight, sound insulation and noise reduction, corrosion resistance, low wind resistance, and easy automobile maintenance are put forward. At present, the engine bottom guards for automobiles mainly include resin bottom guards, steel bottom guards, and aluminum alloy bottom guards. The corresponding engine bottom guards cannot meet the high-strength performance and lightweight design at the same time. Contents of the invention [...
