音波加熱溶着法などが知られている。 Generally, thermoplastic resins are sensitive to heat and melt when the temperature is raised. Heat bonding processing of plastic films is performed using this property, and such heat welding processing techniques include heat welding method, instant heat welding method,
Known methods include hot jet welding, high frequency dielectric heat welding, and ultrasonic heat welding.

部全体を溶融し溶着する。 By the way, the present invention relates to an ultrasonic heat welding method, and as is well known, the ultrasonic heat welding method is based on the following principle. That is, when ultrasonic energy is applied to a thermoplastic plastic film, it is absorbed and heated and melted.
The molten plastic film can be welded by applying pressure. For example, when trying to weld the peripheral part of a bowl-shaped molded product, a wedge shape is provided protruding from the edge of the peripheral part, and the vibrator of the ultrasonic generator is pressed against the center of the top of the molded product to apply ultrasonic energy.
Ultrasonic energy is transmitted inside the molded product and generates heat at the welding part with wedge-shaped protrusions, melting and welding the entire periphery of the molded product.

As a result, glass fiber-loaded thermoplastics are replacing metal materials in structural materials and mechanical parts.

完全な溶着が得られず、そのため、従来の超音波
加熱溶着法では所定の接合強度が得られない。 Conventionally, glass fiber-reinforced thermoplastic resins have been heat-welded using ultrasonic waves, but such thermoplastic resins are intended for those with a low filling rate (approximately 15 to 20% by weight) such as glass fibers. On the other hand, glass fiber-reinforced thermoplastic resins that require strength have a filling rate of 30 to 50% glass fiber, etc., and when performing ultrasonic heat welding on thermoplastic resins with such a high filling rate, conventional The wedge-shaped protrusions formed on the welds that are commonly used become difficult to melt due to the influence of glass fibers with a high filling rate.
Complete welding cannot be achieved, and therefore, the conventional ultrasonic heat welding method cannot achieve a predetermined bonding strength.

These problems can also be solved by heating and welding the joint end surfaces using ultrasonic waves.

The filling rate is preferably about 50% or less by weight in order to maintain plastic moldability.

That is, as shown in FIG. 5, test piece a is made of 66% nylon and 34% glass fiber, and both the first and second members are plates with a thickness of 3 mm, and a protrusion is formed on the joint end surface of the first member 1. It is made by ultrasonic heating and welding. Test piece b is made of the same material and thickness, with a thickness of 50μ between both bonded end faces.
It is ultrasonically heated and welded with a nylon film of m. Both joint surfaces are welded in an area of 5 x 5 mm. Here, when a bonding strength test was conducted, the following results were obtained.

In the case of the following reinforced thermoplastic resins, there were cases in which the joining strength decreased when a plastic film of the same material was interposed.
